A Sinopora identified with S. dendroidea
as a byproduct pf asearch for calcareous algae in the
Permo-Carboniferous limestone complexof Taishaku district. western Honshu.
Japan. Though the species has been
known as an element of the Permian
Tethyan coral fauna. this is the firsttime to be described from Japan.
The coral. from the Taishaku limestone complex is not uncommon in agray. compact calcilutite, which contains debris of various microorganisms
such as smaller Foraminifera, Nubercularia. fusulinids ( Yabeina, Codonofusiella). Nigriporella. calcareous algae(i\1izzia l'elebilana, Gynmocodittm japonicum). and so on. The matrix of thecalcilutite is so completely indurated
that the corallites of the coral cannot
be separated for an examination of their
growth habit. The entire study is. thus,
based on thin sections.
The locality of the specimens examined
is about 1 km east of Zenbutsuji-dani.

Sinopora dendroidea (Yom, Auroporid Coral. from Late Permian

Obserl'ation :-According to You ·I lc,,:-;c, 1932), the species is characterizedby "{1) the dendroid form of branchingcorallites. (2) the exceptionall~· thickexternal wall. and (3) the complete absence of both tabulae and septa ... Thesefeatures are well recognized in theJapanese form.
Corallites arc long, cylindrical. irregularly ramifying, generally wide
spaced. although not uncommonly theycome in contact with each other without any epithecal modification. The
diameter of the corallites ranges from
1.5.J to 1.81 nm1 with average of 1.66 mm.
As Yo11 described, the external wall of
the corallites consists of two conspicuous zones; the outer zone of reticulatestereozone. light-colored, variable inthickness, though in general in theorder of 0.1 to 0.2 mm, and the innerzone composed from fine, irregularly
crenulated, hair-like structure. darker
in color. The wall as a whole ranges
from 0.38 to 0.6~ mm in thickness. No
laminar structure was observed. These
measurements are also identical withthose of M. dendroidea described from
China and Yugoslavia.
Distribution:-This species appears to
be an element of the Tethyan coralfauna during Late Permian. The species
was first established on the material
from the "Zone of Tetrapora elegantula"in the Chihsia limestone at Chi-hsia·
shan (type locality:, and other places
such as Chi-lung-shan. Ho-chou. Southeastern Anhu i (Lower Yantzc Valley\,

Introduction

Our knowledge on the Nymphaeacean
plants of the Cretaceous age of our coun·try is limited, and the only fossil I have
hitherto described is Nelumbo orienta/isin the J\suwa Flora of Fukui Prefecture(1954: pp. 155-158. Pl. XX). In this note
I am going to describe an additional oc-currence represented by small leaves
more recently discovered.
The materials originated in the Omi.chidani bed at road side near the tunnelof Tanitoge, Shiramine·l\lura. Ishikawa··Gun, Ishikawa Prefecture (611!'Ji!,EIII®~~ft 1:1-ih¥) of Central Japan.** These speci·
mens had been collected by N. FcJJ of-our Geological Institute: he. in 1956. re·ported these specimens as Sagcmopteris:sp. in his graduation thesis of the !\·laster* Read Nov. 30. 195i; received Oct. 23, 1959.

When I had an opportunity of study·
ing in the laboratory of Prof. E. Ko:•;':-<oof the Tohoku University in 1951. as ascholarship researcher of the Educational
Department. Prof: Ko~'ro;(, had not been
convinced of FUJI's identification of Sagenopteris sp. and advised me to re·examine the specimens more closely. i\-1yconclusion is that the fossil plant is
Nymphaeites trapel/uides nov. sp. insteadof a Sagenopteris.
Before writing on this report. I wish** In 1951. I collected some needle leaves ofPinus sp. and Pseudo/suga ? sp .. and consideredthem to be of the Tertiary period. In 1959,

and some students.

Gealogical Note
As regards the Omichidani Bed. l\lr. S.
of Chiba Cniversity considered
it a formation of the Akaiwa Group belonging to the Jurasso-Cretaceous System(1952; p. 316), but ivlessrs. S. E:-wo and
M. A~L\:"O (195~: p. 31/) regarded it
younger Cretaceous in age by its con·tents of fossil plants, collected by l'rof.
T. Kun.-n·ASIII of Tokyo Cniversity andl\·ir. S. MAEDA.*
1\-lore recently. the members of the Kanazawa University made observations
that the 6michidani bed unconformably
lies on the Akaiwa (~roup. Thus. I liketo agree with :\lessrs. E:->no and A:-.rA:-.;o's
opinion with respect to the age of theflora.
They reported some fossils as
follows:

Genus lv:vmphaeites(STER;>;BERG) BEJ.L 19c\9According to the text-book oi Gorii:\1'\
and \V EYLAND (1954; p. 3871, the l'iy111·
plweites in the family Nymphaeactae is
explained as "Solche nicht naher bestimm·
baren Rhizome. Bliitter und Fri.ichte
werden meist als Nymphaeites STJ·:RNBERC
bezekhnet."
Thus. this genus had been establishedby Sn:RC'o:BERG for the rhizomes: but mostrecently, BELL emended STER:'\nERc's Nymphaeites. and remarked as follows :"-the genus comprises species incerlae
sedis in the family Nymphaeaceae. Originally based on rhizomes (genotype ~\~vm·
phaea aretlmsae BRoN(;!'\JARTI the con·ception of the genus was enlarged by
IlEEII (1870) to include non-peltate leaves\Vith palmate veins branching at acuteangles. The genus is here further emended to include non-peltate leaves with
mixed pinnate and palmate veins, likethose of Trapa? microphyl/a Lt·:sQL.EREtiX.
as well as pdtate or sub-peltate leaves
with similar nervation and excentric

This species is seen from the description given above to agree with /llymphaeites angulatus (NEwBERRY! BELL fromthe Palaeocene formation in Alberta andSaskatchewan Counties in Canada.

to about 2.5 em long and nearly 2 em

obtuse, and somewhat enlarged upwards:
the borders are minutely dentate except
at or near to the base, rounded to comparatively long and slender petiole. the·only one of the leaves where it is preserved. not even to its base. being 18 mm
long and the petiole 9 mm. The areolation is clearly defined. in \'ery ~m:~ll

is observable upon the lower surface ofthe leaves of the living Trapa natans
LINKE. which though comparable to thesefossil ones, have the borders deeply
toothed, and are of a much thicker texture.- The general form of the slightly·dentate leaves and the remarkably acuteangle of divergence of the secondary
nerves are the same: even the irregular.
though too obscurely. maked divisions of
the lateral veins seem to be of the same

these leaves to TraPa. that Prof. ]. W.

those of Points of Rocks.- ..
In LEsQt:EREt·.x's Trapa \?) microphy!la.
iigure 16 in plate LXI. has a very close
resemblance to Nymplweites trapelloides.
but figures 11 and 1Ia have difference
from it in these areolation. And. moreover, LEsQL'EREL'X (1878; pp. 102-103, Pl.
LXI, figs. 2. 5.) tried a descriptive investigation on Lemna scztfata DAwso:-; in thesame paper. I think his figure 5 in plate
LXI belongs to the genus ]\'ymplweites.
but his figure 2 may be Lenma. andshould be assumed to be aquatic in life.
Then. BELL (1949 : pp. 64-67) explainedthe ~\~nnPfweites angulatus as follows :·'The taxonomic position of Trapa (?)
microp/iy/la LEsQvEREllx (Neuropteris angulata ~EwBERRY) has remained questionable ever since LEsQUERErx's description of the species. -The venation isbest displayed by figures of LEsQUEREL'X
and BERRY. Both these authors. however,show the veins terminating craspedodromously at the margins, whereas actually
the veins. or at least most of them. in
specimens observed by the writer are
joined in a pseudo-marginal Ycin very
close to the margin as in J\~vmplzaeites
slriatus IBERRY). Most commonly thefmer details of the venation are not preserved. and in many instances the veinsare entirely obscured, as if the leaf substance \Vere thick and fleshy. Not uncommonly the surface has a microscopic.
granular or pitted appearance. -Although the dominant form of :V. angulattts
has a rounded or truncate base, it may
show a variation on the one hand to amore cuneate base. and on the other toa slightly cordate base such as that present in :-.JEwBERRY·s type specimens of
the species. A variation to the peltate
leaf to :Vymphaeitcs stria/us is likewisestrongly suggested. The two species areclosely associated in the same beds inboth the upper Cretaceous Whitemud
and St. Mary River formations. -1\~wn­
p/weites angulatus was one of the few
species tlmt_cro_ssed the Cretaceous-Paleocene boundary. but it apparently had its
acme in the late Upper Cretaceous time.
Nvmphaeites slriatus has not yet beenfound in Canadian Paleocene formations,a fact that may support its status as a
distinct species. but as pond or lake deposits are rarer in these formations, its
apparent absence may be due to greater
rarity of preservation.-"391.

On the New Nymphaeacean Plant from the Omiclzidani Bed

consider. however. that Nymphaeites
stria/us may have no relation with N
angulatus: as the former shows the nervation radiating from nearly the central
part just like we see in the Braisenian
nervation, while the latter shows thenervation ternating from petiole.

figs. 4-7) etc.: but they were in doubt
as to whether this fossil belongs to the
Trapa or not: BERRY, among them. said"-since it can hardly be considered atrue Trapa in spite of its occurrence inassociation with aquatic plants. and in
spite of the fruits of Tmpa being found.
at least in one instance. in the samebed."
So far as I know. a fruit of this lliymp/weites trapelloides has never been associated with leaves. and the areolation
does not suggest to be of the modern
aquatic plants. Trapa and Trape!la. rather
coinciding with that of the Nymphaeacean leaves.
The differences, however, bet ween the
new species and Nymp!taeites angulatus
with leaves of larger size. are in two
major features. First. there is the difference in the geological occurrence, the
new species being yielded from the lower
part of the Upper Cretaceous (or theuppermost part of Lower Cretaceous ?)while the other occurring in the Cretaceous-Palaeocene boundary. Secondly. thedifference in size of leaves are marked :while the new species shows 7 to 20 mm
in length (10 to 12 mm in majority), the;~;~:)

other species Yaries from 4 to 30 mm inlength (those from 18 to 20 mm being
abundantl: evidently the former species
is smaller than the latter ones.
This species is named to show that itis Trapel/a-like. Though many authors
have named Trapa ? microphylla for the.Vymphaeites augulatus. its leaves moreclosely resemble those of Trapel/a thanof Trapa.
Moreover. there are some other species
resembling the new species. The firstexample is Dicoty/opllyllum cen:ifonne in
the Upper Cretaceous bed of Cereal in
Portugal, reported by TEIXEIRA (1948: p.
77. pl. XXXI. figs. 9-13'. D. cerc~forme
was name by SAPORTA 11894: p. 147. pl.
XXV]. figs. 14. 14a), who established three
species of Dicoty/ophyllum.* These had
been an unknown Dicotyledunean small

Cereal e as lentilhas de agua (Lenma)
actuais."However. I consider that his species
may belong to Nymphaeites. but not to
the genus Lemna, because it shows the
Nymphaeacean areolation. Therefore I
dare to emend it to the former genus,
and call it "Vympltaei/es cerc~(ormis. It issmaller than the N. trapelloic/.'s, and slight-* His other two species of D. hedemceum(p. US. pl. XXVI. fig. 15) and D. corrugatum(p. 148. pl. XXVI. fig. 16). I consider thatthey are synonymous with D. cerciforme.

as the former has been unknown to beserrated.
The second example occurred in the
Ryoseki Flora (Lower Cretaceous, sameas the Wealden Flora) at Tanzaki i'uasa·
Machi. Wakayama Prefecture.
OtsHt(1940 ; pp. 3!i3-36·l, pl. XL VII. figs. 3-5 :Type specimen is fig. 3.1 described as
Sagenopteris ? inequilateralis. And his de·scription reads as follows:" -Frond with 4 leaflets: leaflets obo·

1.5 em broad in their broadest portion.

But this figure 5 in plate XL VII, showssome such characters of 1\innp/weites. as
the veins being radiated from the top of
petiole, and the fine serration along the
upward margin. Therefore l am quite
sure that these specimens represent a
species of "\~·mphaeites. and that they be·long to N. trapelloides.
The third example closely resembles
Nymphaeiles cmgulalus exca\·ated fromthe Nilssonia·bed of Hakobuchi Sandstone
Series \the upper most of the Cretaceous
System in Hokkaido), which E:-:oo (1925 ;pp. 62-63, pl. X\'11, figs. 16, 18, 19.) re·

On investigating his samples in the re·pository of the Institute of Geology andPalaeontology, Tohoku University in Sen·dai. I become aware that he committed
an unfortunate mistake in the identification. He failed to notice the petiole ofleaf and took the Cycadalean venation for
the areolation of these leaves. Judging
from these characters, it seems clear that
G!ossozamites (?) imaii is specifically distinct from Cycadalean species. and I
consider that these specimens bear thecharacteristics of the species of Nym·
phaeites closely related to N. an~Iulatus
from the upper Cretaceous bed of North
America.
These species are thus summerized in

The distribution and geological signifi·

From the above mentioned. I consider
that the Nwnp!weiles referred is a small
aquatic plant. and ranges from the Lower

Ambulacra distinctly petaloid and open
distally, all petals reached to the ambitus and very slightly sunken adapicallybut flush with the test distally. They
are gradually widened towards the distal
ends of petals. The odd anterior petal
is narrower than the others. Petals III
and IV extend straightly towards theextremities, I and V are somewhat flexuous backwards, II is more or less flexuous
forwards. The interporiferous zones arebroad. Pore-pairs all alike. The apicalsystem situates central : genital poresand madreporite are indistinct. The
periproct is not observed due to lackingof the posterior margin of the test.
The marginal and submarginal fascioles
are indistinct. Oral side fiat but concave

orally. phyllodes somewhat developedaround the peristome. The peristome is
lunar in shape and is situated at nearly
1/6 diameter distant from the anterior
margin. The labrum and sternum are
not observed due to lacking of this area:
Dimensions :-92.6 mm. in length. about
80.0 mm. in width. and 32.5mm. in height.
Remark~ :-\Ve have already known
three reports r 1931. 1933 and 1953) on
the fossil cchinoids referred to Palaeo·
pneustidae from Japan. Very recently.
H. UJJJE described Linopneustes sp. fromthe middle part of the Horinouchi for·mation. Kakegawa group (in press).
The present form differs from Palaeo·
p11eustes cristatus in its lower height andthe longer ambulacra and stands nearer
to the Pa/aeopueustes cf. crislatus A.
AGASSIZ of [vloRISHIT A !1953) or Palaeo·
pneustes sp. nov. of N'JsliJY,\~Ic\ (1931)
from Soma, Fukushima Prefecture. In
every aspects, these three species seem
to us that they probably belong to one
and the same species. ho\vever. we feelsome he.'litation to establish a new species based on the present specimen due
to its incompleteness of some importantpart though it is· very slight.
It is noteworthy that the echinoid

species belonging to Palaeopneustidae,
as far as described. usually occur in thealternation of sandstone and mudstoneof Tertiary age. especially of the lower
Pliocene age. as already stated by A.

Introduction and Acknowledgements

This paper contains a description of a
new species of Neocalamites collected by
N. 0KAnF. and the junior author in
195·1 from the iVIomonoki formationof the Mine Group at about Lat. 34 "11'N. and Long. 131 '10' E .. Yamaguchi Prefecture. Japan. with some brief notes on
Neom/amites and Lobatmmu/aria in Asia.
After his preliminary investigation. thejunior author entrusted the senior withdetailed examination of his materials,
which are deposited in Geological andPaleontological Institute of the Tohoku'Cniversity (IGPSJ. Mainly because of
the presence of the large terminal leafwhorl as well as the lateral one divided
into two lobes, both showing somewhat
marked anisophylly, the present authors
referred these specimens at first to Lobatannularia. but they would now preferto bring them into Aleucalamites for* Received Nov. 16. 1959: read ::'\ov. 30 1957.

reasons. which will be giYen and discussed in details in the present paper.
The 1\-Iine Group is generally subdivided
into such three formations as in descending order: Aso. Momonoki, and Hirabara. Of them the JVIomonoki formation,
though llalobia sp. aff. aotii was collectedby the junior author from its uppermost
horizon. consists mainly of non-marine
sediments wi1 h rich plant fossils andseveral workable coal-seams, overlain
conformably by the Aso formation andunderlain with some slight disconformity
by the Hirabara. (HAsE. 1950, pp. 113119: ToKt:YA:-.IA, 19;)8, pp. 454-463.1. According to the correlation-table of theTriassic System in the '{amaguchi Prefecture given by T. KoiHYASHI, K. lcuiKAWA and A. IL... sE (lcHII<AI\·,,, 1951, p.
2), the Mine Group is considered as Carnic in age, representing the lower halfof the Neo-Triassic Series in Japan. andthus the lower part of the l\lomonoki
formation. from which our present specimens were collected. is safely referable to340

and its allied genera. This study waspartly financed by a grant from the Science Research Fund of the iVlinistry of

whorl to judge from its individual leaves

being extremely shorter and thinnerthan the rest. The other specimen alsowith four joints shown in Pl. 40, fig. 1 bcoincides with the above mentioned typein every important respect as: the internodes reduce the length successively andA new Neocalamites from the Carnic Formation in Japan

unfortunately no substance of internodeis preserved. At first glance this specimen appears to bear two branches ofunequal length one on each side of thenode. and if really so. then the ramification of this specimen resembles to acertain extent that of Lobatawmlaria.
The ramification is evidently one of themost important criteria to distinguish
Neocalamites from Lobatamuelaria as will
be discussed in the following chapter.
Unfortunately, however. the present
specimens are too imperiect in preservation to draw any reliable conclusion on
the ramification of the present species
therefrom.

typically 75 mm. long by 5-5.3 mm. widewith the midrib 1.3 nun. acros:;. whereas
in the l'vlinor type they are ,lO mm. longby ~.5 nun. wide with the midrib of 0.63
rnm. in width. Thus bet ween these two
types there is a considerably wide gap
in size. because the leaf of the Major
type is about I wice as long and wide asthat of the other. and so is its midrib
in thickness. To ascertain if there are
specimens of intermediate size. themaximum width of both lamina' L' andthe midrib(l\1) of all the available specimens at our disposal were carefullymeasured, and the results 1L /?vi 1 aregiven in mm. below:
J\Iajor type: 3.0 x 1.0 (Pl. 41. fig. 3 ..to
Xl.O, 4.fixl.l. cl.5Xl.35. 5.0xl.35. !i.3x1.2.
Minor type: ~ 5x0.6. ~.5x0.7. ~.8 .tll.63.
Intermediate type: 3.0 x 0.8. 3.8 ., U./5,
3.9x0.9.
Judging from these measurements ex·cluding 3.0xl.O (Pl. ·11. fi,g. 3t, several
leaves included above in the Intermediatetype seem to prove the presence ofvarious intermediate sizes linking theother t\VO types with each other. ]\loreover except the marked departure insize, the tvlinor type coincides nearlycompletely with the l\lajor type in feature of a leaf-whorl.-especially in formof the individual leaf-segment. As shownin Tables 1 and 2. the ratio of length
to breadth of each leaf-segment ranges
in the Minor type from ~5/2.5 to 40/~.;;.
that is from 10 to 16, while in the l\lajor
type from 60/:l to 7~/:1.3. 1hat is from1~ to 14.
Judging from all of theseevidences it would be more preferable
to place the i'vlinor type in one and thesame species defined by the type-specimens belonging to the l'vlajor type toseparating the former type even as avariety of the present species from the!at ter. To say in 'other words, such a.small size of the l\linor type would pre-:l4:3

sumably be due to that it belongs to the
distal part of a large leafy main stem
represented by the .Major type, insteadof immaturity in development of a youngshoot.
Comparison t(·itil other sPecies:
Comparison with Lnbatanmt!aria
e11s((o/ia (HAI.LE J.--This Permian species
occurs in the l'pper Shihhotse Series in
Nort hen China. the Gigantopteris-bearing
formations in Southern China and theKobosan Series in Korea. Specimens of
our l\'lajor type resemble to some extent
the specimens of HALLE's with leafwhorls consisting of leaves entirely freeto the base. e. g. that shown in his Pl.
I. fig. 1 (1-IAI.LE, 1927). Both of them
have such characters in common as :1) normal leaves are very large andlinear traversed by thick midrib \Vithstiff mucro at apex, ~~ the terminal
whorl is large and fan-shaped and either
the terminal or the lateral whorl is flattened in a plane nearly parallel to theaxis. :i) lateral leaf-whorl is divided into
two distinct lobes with a wide gap between them in the basal side, ·l) leaves
near the basal gap of a \Vhorl are shorter
than the rest. Thus these two species
agree with each other in having thedorsiventral ultimate branch with anisophyllous leaf-whorls. But L. ensifolia
differs rather considerably from the i.\'line
species because in the former 1) leaves
near the basal gap of a whorl arc much
shorter than the rest and spatulate inform. 2) anisophylly is much more pronounced. the longest leaves are at least
3-4 time and some! imes 8 times as longas the shortest ones, whereas in ours
they are only 1.8 or less times, 3) leavesof a whorl usually cohere for some distance. while in ours they are entirely
free. 4) the stem shows a peculiar ramification called pseudodichotomy. Thus
(1)

Enzo KoN·No and Gentaro NAITO
it is certain that the distinctions between
the two species much outweigh the similarities, but it seems worthy to notethat these two species, though very remotely separated in age, are equallycharacterized by the presence of thelarge fan-shaped terminal whorls and thedorsiventral leafy ultimate shoots.
(2) Comparison with Lobatammlaria
ensifolia (HALLI') var. nariwaensis KouATAKE.-This variety occurs in the Upper
Triassic formation near Nariwa District,Japan. KooATAKE (1954, pp. 71-72, Figs.
1. 2) gave only three illustrations of thedetached tem1inal whorl with short description. To compare them with our
terminal whorls of the Major type e. g.
those shown in our Pl. 40, fig. lc andText-fig. 2A. there arc some close resemblances found between them, e. g. theleaf-whorl is anisophyllous. composed oflinear and entirely free leaves, provided
with a wide gap in the proximal side of
the whorl, etc. However. the differences
appear to outweigh the similarities, because in the specimens of KonATAKE·s
the anisophylly in the leaf-whorl is much
more remarkable as clearly shown in his
11g. 1, in which the longer leaves in the
middle of a whorl measure 60 mm. in
length by 8 mm. in width, while theoutermost basal ones are 13 mm. by lessthan 6 mm. and accordingly ratio oflength of the longest to l he shortest
leaf is 60/13=4.5, whereas in the present
species it is only 1.8 or less: the leafsegment of the former is generally shorterand broader than ours by about 70 mm.
in length and by 5 mm. in width ; basal
leaves nearest to the proximal gap of
the whorl are spatulate in the former,
while in ours they are linear-lanceolate.
Among these distinctions. the marked
anisophylly is evidently most essential
and but for this distinction the varietyof KoBATAKE's might hardly be distin-

guishable from our l\fine species. To
recognize such the anisophylly correctly,
the length of leaves.-especially of thosenearest to the basal gap should be correctly measured. In KouATAKE's illustration of fig. 1 the outermost basal leaf
is drawn to have a complete outline.
However, it seems strange to find that
this basal leaf on the left-hand side ofthe leaf-whorl points straightly backwards without showing any further outward or forward bending, and further
that the adjacent leaf lying just above
this basal one appears considerably
longer. possibly attaining, according toour estimation. about twice as long as
the basal one and if so, then the change
in length from the basal leaf to the next
upper seems to be too abrupt to be expected as natural. Having no opportunity
to examine his specimen for ourselves.
we requested KonATAKE to re-exmine
the length of his outermost basal leafof the specimen shown in his rig. 1. In
his kind answer he said that there wasno need for his illustration to be corrected. but such missprints in his description of the basal leaf of a whorl in
fig. 1 as "18 mm. long by 6 mm.'' should'
be corrected as .. 13 mm. long by a little
less than 6 mm.". As to the form of theleaves in the middle of his whorl, KonATAJ.::E described it as linear-lanceolate,but his illustrations appear to show it
is rather linear-oblanceolate, and if so·
the specimens of KoBATAKE's resemble
to a certain extent some of either Lobatamwlaria ensifolia reported by HALI.E(1927) or Ammlariupsis inopinata ZErLLER?
by Or sur (1930, pp. 51-52, Pl. VI I. fig. 1).
Though all of these specimens reported
either by KoaATAr<E or by Orsrrr seem
too imperfect to permit any reliable
comparison with any definite genera as
Lobatammlaria. Ammlariopsis, etc .. they
are important in proving that such the393.

A new Neocalamites from the Carnic Formation in Japan

Equisetacean plants characterized by the
Ammlaria-like leaf-whorl with oblanceolate leaves were still existing in theUpper Triassic age in Japan.
(3) Comparison with JVeocalamites car.cinoides H,\fiRis.-This species was established in 1931 based on numerous specimens from the basal Liassic beds in-Greenland (fiARR Is, 1931, pp. 2:=i-30 : Pl.
IV, figs. 2. 3, 5-7: Pl. V. figs. 1·-5; Pl.
VI. figs. 1-6: Text-fig. 5A-D.). and recently SzE ( 1956. pp. 120-122: Pl. I, figs.
1. la: Pl. II, figs. 1, la, 2; Pl. lll, figs.
1-3: Pl. IV, figs. 7. 8; Pl. IX. figs. 1-3)
referred his specimens from the Yenchang formation(Carno-Rhaetic) in Northwestern China to this species of H.'\RRis's.
HARRis described two sorts of his specimens of the leaf-bearing shoot. i.e. TypeB of lateral stems with normal leafwhorls and Type C of small :>tems
characterized by leaves fused in twolateral groups. and then he chose thespecimen belonging to Type B IText-fig.
SA) as the type of his species. His typespecimen. which consists of a slender
lateral stem with three internodes andthree lateral leaf-whorls. resemb es very
closely that of the present species (Pl.
41, fig. 4: Text-fig. 2B). though in theformer the apical part of the shoot is
unfortunately missing. In both of thesetype-specimens of HAIH~Is's and ours aleaf-whorl is large, consists of leaves
entirely free to the base. flattened in aplane nearly parallel to the axis : lower
leaves of a whorl point slightly backwards and then bend outwards and forwards, leaving thus a very wide gap inthe basal side of the whorl : a leaf isvery long and gradually tapered towards
acutely pointed mucronate apex. Our
type-specimen, however, differs from thatof HARRrs's in the following respects: 1)
anisophylly of a whorl is more 'pronounced, 2) leaf is shorter and broader:>,.15(70 mm. long by 5 mm. broad in theformer. while 90 mm. by 3 mm. in thelatter), 3) leaf is linear-lanceolate and not
petiolate. 4) leaf-whorl consists of about
10 leaves instead of 14-18 in the latter,5) terminal whorl is large and fan-shaped.
Thus I he present type-specimens are
distinct enough from .V. carcinoides tobe worthy of specific rank. Besides thetypes, all the ol her specimens of both
Major and the r-.·1inor types resemble
also closely the type-specimen of HARRis's.
especially in feature of the basal regionof the leaf-whorl. Thus it is sure thatthe present Min<.( species resembles wry
closely the leafy lateral stem of Type B
of HARRis's species. However, with the
Yenchang specimens appears the matterquite different. To judge from six figuresof the leafy lateral shoot given by Szt.:(1956). in the Yenchang specimens a leafwhorl is generally divided into two lanceolate or linear-lanceolate lobes. leaYing
between them wide gaps in both basal
and the apical sides of the whorl : leaves
in each lobe run nearly parallel witheach other for the most part of theirlength and then often slightly con\·erge
together in their apical region. In thepresent Mine species. on the contrary,each lobe of a whorl is cuneate or obovate in form with its leaves not convergent but divergent throughout theirwhole length. Thus so far as concerningwith the form of the sheath-lobe only,
the Yenchang specimens. as previously
suggested by P'AN (1936, pp. 13-14, withhis material. resemble Schizoneura moreclosely than any other known species of
Xeoca/amites. l\'loreover in Neocalamites
the midrib of the leaf is thick. persistent and single or double in composition,
often terminating in a stiff mucro at
apex of the leaf, while in Schizrmeura,as cleared up by WILLS (1910a, 1910b),
the midrib is multiple being composed

of several fine netYes. In the Yenchang
examples. according to ·szE (l!lS6. p. l ~Ol.
"the midrib of leaf is generally notvery conspicuous on some specimens.".
and accordingly they differ in this respect also from our Mine species. but
appear to resemble to some extent SdtizonRura. They cannot. however, belong
to .'\chizolleura. if the following inter·
pretation of SzE·s 11956, p. 120\ is correctas: "The whorl of leaves are probably
flattened into plane of axis by twistingof petiole during the life of the plant.
The leaves are usually free to theirbases.", because in Schizoneura leaf-whorl
is generally divided into coherent andconstantly amplexicaul lobes.
But itseems often quite difficult to determine
whether these leaf-whorl were originally
flattened in the plane of axis during thelife of the plant or they were originallyamplexicaul and subsequently crushedduring fossilization so as to assume also
such the flattened condition. vVhen thepresence of the fan-shaped terminal
whorl as well as the anisophyllous leaiwhorl is clearly ascertained. then suchthe leafy branch can prove to have theleaf-\\·horl originally flattened in the planeof axis instead of amplexicaul. but among
specimens reported by SzE (1956) neither
fan-shaped terminal nor markedly anisophyllous leaf-whorl can be found. Fromthe same formation many well-preserved
specimens of the main stem were reported
by SzE under the name of Neocalamites
carcinoides llAI~RIS, but it is not always
easy to distinguish Neocalamites from
Scltizoneura by means of the feature of
the leafless stem. ZEILLF-R (1902. pp. 2627. Pl. VI, fig. 1) reported a similar specimen of the main stem of about 31mm.
width attached in organic connection bya lateral leafy branch of definitely of
Schizoneura gondu·anensis type, in which,according to ZEILt.F-R (1902, p. 26), .. lescote de la tige taniot alternent d'une
articulation <1 !'autre et tan tot t ravcrsent
sans dl:viation !'articulation."' Further,.
numerous similar examples of the mainstem belonging evidently to 8cltizoneura
parado;m were reported by W1t.1.s (HllOa ..
1910bl from the lower Keuper beds in
England. In general feature. at least
the specimens of \ViLts's A type quite
agree w .. th Neocalamites ltoerensis andothers. and. according to WILLs (1910a.
p. 281 '· ·· It is of interest to note that
whereas in N. lwerensis and also N. carrerei these prints (leaf-scars) are separated
by only one or two ridges, in our specimens there may be as many as eight
between two consecutive ones." In the
Yenchang stems, according to SzE (1956.
p. 120), ··The leaf-traces are separated.
in large stems by about 5-6 ribs occasionally by 7 ribs. and in smaller onesby ·1 ribs." The leaf-whorl of the leafy
branch is composed in the Yenchangspecimens of 10 leaves of more than 2\fem. length by 5-6 mm. width, while inspecies of HARRis's and \V11.Ls·s it consists of 14-18 lea\·es of 9 em. length by
3 mm. \~vidth. 7 leaves of more than 1~
em. in length by 5-6 mm. in width, respectively. Thus in various respect thisYenchang plant appears to sho\v someintermediate feature bet ween Neocalamites
mrcinoides HARRts and Schizoneura paradoxa WILLS sp.. which tells these specimens of Sz1c's seem to be somewhat considerably different from the species of
HARRI:-;'s. Thus we come to the conclusion that the present Mine species resembles most closely Nl'ocalamites carcinoides HARRis \llOn Su:). but differs
even from the latter in that the leafy
stem is more markedly dorsi ventral withanisophyllous leaf-whorls either lateralor terminal. As above stated N carciuoides was established in 1931, but thereafter in Hl3'i this generic name was sub-

stituted by H,,RJHS himself for Lobatanmtlaria in acceptance of such opinion of
KAwASAKI's (1934. p. 66j that "HARRIS
specimen shown in text-Jig. 5A under
Neocalamites carcinoides sp. nov. closely
resembles Lobatamwlaria in the characteristic arrangement of leaves of whorls."
This substitution, however, was not accepted by the present senior author.
1\:;.\~IA and SzE. who insisted to call it
by HARRis's original generic name. But
it is evident that the leaf-whorls of N.
carcinoides show some slight resemblance
to those of Lubatannularia. and further
that those of the present species bear
more resemblance to Lobatmmularia than
the species of H.\RRrs's in having themore markedly dorsiventral lateral shootwith large fan-shaped terminal whorls
and clearly anisophyllous leaf-whorls.
The reason why we would prefer toplace the present species too in .Veocalamites instead of Lobafannularia can befound in the reason \vhy this substitution of HAREus's was not accepted by us
as will be discussed in details in the next
chapter.
Notes on Neocalamites and

Lobatannularia andconclusion
There is no doubt that the present
Mine species is referable to either Lobatannularia or Neoralamites and not toany other genera hitherto known. Lobatammlaria is the Permian plant knov-m
only in the Cathaysian Flora and its
single survivor, L. nampoensis. in RhaetoLiassic flora in Southern Korea. On theother hand Neocalamites is a \\·ide-spread
plant in the older Mesozoic. occurring
most abundantly in Keuper and RhaetoLiassic formations in the world. Thus
the respective age of zenith of their347

luxuriance is some\vhat remotely separated, and consequently the typical
species of each genus are easily distinguishable from one another. However. there
are many forms intermediate in feature
between them. e. g . •4mmlariopsis inopinata ZEILLER, Lobatannu!aria ensifo!iavar. naritcaensis K(JI3t\TAKE, etc .. and thepresent species is also the same case.
Genus Lobatmmularia 'S. 1.) is characterized by such features as: 1) leaf-segment is uninerved. either spatulate, oblanceolate or linear in form; 2) leaf-whorlmarkedly anisophyllous. flattened in one
plane nearly parallel to axis: 3) ultimate
leafy branch generally has a circular fanshaped terminal whorl and lateral leafwhorl divided into two coherent lobes
leaving a wide gap in the basal side ofa whorl: 4) main stem at least t\vicebranched. with penultimate lateral stem
showing very characteristic ramification.
Although as to the feature of the mainstem nothing has been known, various
opinion were expressed on the ramification of the penultimate lateral stem by
HALLE ll927. 1928). KA\\'ASAKI (1934),
Ko:-;':-.;o (1933i. Ko:-.':oo1o and AsA~IA (1950\,
etc. Ko:-:'"o and AsA\JA (1950. p. 23) gavea brief summary on the ramification incescribing two types of it : the one shownby L. sinensi~ IIIALLE). L. lingulata(HALLE). and L. lwianensis tKoo,\IRA/. andthe other represented by L. ensifolia{HALLE). The first type shall be called
pseudosympodial distichous and thesecond was called pseudodichotomous by
H... t.LE 11927. p. 21). In the first type.
a;; pointed out by BALLE (19:28. pp. 2442·15). each pair of ultimate branches arc
arranged in two ro\•.-s on the flanks ofthe penultimate axis. and the branchesof each side are quite unequally developed-long branches with numerous
whorls alternate with short ones carrying only a few or a single whorl; on348

the upper part of the same mother-axis
the shorter branches become undevelopedby abortion and at the same time thelonger ones are also shortened and remain in solitude at each node: at last
even the solitary branches entirely disappear in the apical part of the same
axis. It is quite noteworthy that thisparticular plan of branching remained
unchanged from the beginning of the ageof L. sinensis (of Taiyuan, the early Permian). through L. lingula/a to the endof that of L. lzeiane11sis (of Upper Shih·hotze Series, lower of the later Permian).
Other characters. e. g. cohesion of leavesof a whorl changed progressively along
the trend from non-cohesion to complete
cohesion. To say in other words, thesethree species. i.e. L. sinensis. L. lingula/aand L. heianensis represent one distinctive group to be called Siuensis-lingulataheianensis Series, and this Series can heregarded as a direct descendant of genus
An11ularia. On the contrary other typeof ramification shown by L. ensifolia is.characterized by four branches at a node.
and accordingly it appears essentiallydifferent from the first type as well as

Amwlaria. For this reason L. l'llsifolia
should be excluded from the typical
Lobatrmnularia (s. s.) characterized by
Pseudosympodial distichous ramification,and be placed in Ammlarites HAu.E 1927.
as previously suggested by KA\L\SAKt(1934, p. 68).
Neocalamites was first proposed by
HALLE for such three species as: Sdlizrmeura hoerensis Sc11t~ti'ER (type-species),
Sch. Merim1i (BRo:"GN.) and Sch. Carrerei
ZEtLLER in 1908, when he said as follows:"Ich habe es fiir zweckmiissig gehalten
aus die Gattung Schizonettra die Sdz.
lwerensis ScHJI\t. und andere Arten mit
konstant freien Blatter auszumerzen."(HALLt·:, 1908, p. 6). In N. Carrerei and
N. hoerensis the main stem is once
branched with a single or a few branches
in a whorl respectively on certain of thenodes (ZEJLLER 1903, p. 137: HALLE. l!JOS,
pp. 10-11).
After studying various
Equisetacean plants from Keuper bedsin Germany, fRENTZt:N (19:33) gave asplendid restoration of l•>i. ,1feriaui(BRo:-:G:-..). in which the main stem isdrawn to be twice branched and thepenultimate lateral stem to bear a single

branch at a node. \Ve are not certain
by what fossil evidences his restorationof the penultimate stem was drawn. but
such the ramification of the lateral stem
seems for us to be highly possible tooccur in Neocalamites. However. withthe ramification characterized by distichous arrangement of branches on thelateral stem. seems the matter quite different. BERRY (1912. pp. 174-180, fig. 1/)
reported a very peculiar Rhaetic plantfrom Virginia in U.S. A. under the nameof Neocalamites Knmclto11i n. sp. Only asingle specimen was figured in his paper.
in which the axis is 8 mm. across with
six pairs of opposite dorsiventral leafbearing branches preserved in organic
connection to the axis: leaf-,vhorls of
the lateral stem are flattened in theplane nearly parallel to the axis : leaves
in a whorl are free to the base. of approximately the same size. linear-lanceolate and about 15 mm. long. Besides apair of opposite leaf-bearing branches.
one or two branch-scars are also seen
on some of the nodes. and these scars.
according to BERt~Y. may be interpreted
as the scar of such aborted or non-persistent branches. BERRY 11912, pp. 1/8179) said as follows: the 8 mm. wide axisof the figured specimen. .. with its leafbearing subordinate branches. is interpreted as a lateral branch which was
distinctly bifacial in habit.-It is more
like Calamites, however. than the species
which HALLE has referred to the genus.
and suggests most strongly the Ammlaria
type of Paleozoic Calamites foliage. forexample. the widespread type known
as A.nnularia sphennphylloides,-." If thisinterpretation of BERRY's is correct, thenin this American plant the main stemmust be twice branched; the penultimate
lateral branch bears distichous ultimate
leafy branches of distinctly bifacial habit; if so. then this scheme of branching:H~lcannot be of the ]'{eocalamites type. but
evidently of Awmlaria type, as suggested
by BERRY himself. Nevertheless. longitudinal furrows on the surface of thestem are not alternate at the node. andin this respect it is more like lVeocalamites stern than Calamites. Despite ofsuch remarkable departure from thetypical Nl'f!Calamites, HmMER (19~7. p. ·163)
and HARRIS (1931. p. 22) placed thisAmerican species in Neocalamites without giving any important comments. but
such references seem to be quite doubtful for us. We \vould rather prefer to
exclude this American species from thetypical Neocalamites, which is characterized by free leaves of a leaf-whorl
and a single or many branches arranged
in radial symmetry at a node. This
American species. is, however, quite important in proving the fact that such the:\mm/aria-like plant retaining the definitely Palaeozoic aspect was still existing in the Rhaetic age in North America.
.ll.'eocalalllifes carcinoide~ lL\tHWi, on thecontrary. is evidently typical and wellestablished. adding several important
contributions to our knowledge of .\'eocalamites. The main axis in this species
is once branched. \vith numerous lateralbranches arranged in radial symmetry at
a node; lateral foliage-stem is dorsi ventral with leaf-whorls divided into twolateral groups. flattened in the plane ofaxis. Terminal leaf-whorl has not beenfound as yet. but its presence would behighly possible. judging from the specimen of HARRts's given in his 1'1. \',fig. 3.
This well-founded species was. unfortunately transfered to Lobatannularia in
1937 only because of its leaf-whorl being
divided into two lateral groups and flattened in the plane of axis. The present
senior author and As.\~tA (1950, p. 20)
expressed a view against this substitution of H,\RRts's saying ·• It has neither

Enzo Kw.. ·No and Guztaro NAITO
fan-shaped terminal whorl nor characteristic branching habit of Lobatannularia.
Accordingly it seems more preferable toseparate this species from the typical
Lobatmmularia." On the same problem
SzE (1956, p. 121) expressed a more decisive opinion. saying as follows: " All thecharacteristic forms of leafy shoots of
the Palaezoic e. g. Amwlaria. Asteruphyllites. Lobalammlaria etc. are attached tothe stems of definitely Calamites-type.
For this reason. the writer would preferto name the Greenland species as Neocalamites carcinoides l-IAR 1<1s." Though
about the main stem nothing has
been known, Lobatannu/aria is sure tobe essentially different in ramificationfrom _Veocalamites. and in this meaning
the present authors agree with SzE in
his vie\\'. Thus N. carcinoides is evidently
one of the typical species among !Veocalmites and also characterized by its
clorsi\'entral (probably plagiotropicalJ
branches arranged in radial symmetry at
the node. The present l\Iine species
coincides with this species of HARRis'sin various characters as : the leaves in awhorl are entirely free eYen in its distal
part of the ultimate stem : leaf is not
oblanceolate but long linear-lanceolate inform ; lower leaves nearest to the basal
gap of the whorl are also linear-lanceolate

instead of spatulate as in Lobatammlaria.
For this reason we would prefer to place
this Mine species too in genus Neocalamites. Unfortunately, however. we haveno reliable evidences at present to prove
its ramification. and so far as its ramification is left uncertain. the reference ofthe present species to Neocalamites would
also be not decisive but only provisional.
Before leaving the subject of the taxonomy of the present species. attention
may be called once more to the following remarks of SzE 's (19:16, p. 121): " Forthis reason, the ·writer \vould prefer toname the Greenland species as Neocalamites carrinoides HARRIS, and the samecan be said for the Liassic species of
Korea which was first determined by
KA ,,. -'•SA K 1 as Sclzizoneura
nampoensis!KAWASAKI 1921, Pl. Vll, fig. 29; see also
01&111 1940, p. 18Gl.
This single specimen
found from Korea is certainly also attached to the stem of definitely lVeoralamites type.'' \Ve have. however, not beenacquainted with the specimen of Lobatanmtlaria nampoensis having the stem goodin preservation enough to prove the feature of the nodal region of definitely
Neocalamites type. Of three specimens
