Vellozia hatschbachii L. B. Smith & Ayensu, new species (photograph by Edward S. Ayensu). 
A Revision of 

American Velloziaceae 

Lyman B. Smith 

and Edward S. Ayensu 

Introduction 

Since Smith's first revision of American Velloziaceae (1962), several times as many collections have 

become available for study and new techniques of 

research have been applied to the family. In fact 

much as we would like to take the time for a monograph it seems advisable for us to take stock of the 

present situation and expose our findings for use 

and criticism. On the one hand a number of new 

species must be published to give a taxonomic base 

for other lines of research as 28 new species in 103 

of Barbacenia and 26 in 122 Vellozia testify. On the 

other hand generic and subgeneric lines are still 

unsettled and it is desirable to reach a better accord 

before proceeding to a monograph. 

Collections by the staffs of the United States National Museum, the New York Botanical Garden, 

and the major Brazilian institutions have greatly 

increased our knowledge of the American Velloziaceae by numerous new species while showing the 

extent of variation and the reliability of characters 

in various old species. At the same time loans from 

several European herbaria have made possible exact 

classification and illustration of species that were 

formerly not well understood. 

At present our basic difficulty in the delimitation 

of genera is the difference between Vellozia and the 

typically Old World genus Xerophyta. Menezes 

(1 97 1 b) would place certain Brazilian species of 

Velloziaceae in Xerophyta because they have only 6

stamens, but she would disregard the character of 

stigma form and type of floral appendages. This 

stamen character is untenable on two counts, the 

number 6 or one to each tepal breaks down in certain species with more than 6 but less than 12, while 

the coronoid appendage character is contradicted. 

By retaining these species in VelZozia we believe 

that we have a much more logical system. 

Our studies in Barbacenia have progressed less 

than elsewhere in the family and our arrangement 

of species here is completely artificial. Menezes has 

separated one genus, Aylthonia, from Barbacenia 

(1971b) and has announced but not legally described another at this writing. The single character 

of connation of the coronoid appendages and the 

close resemblance of species of Aylthonia to some 

remaining in Barbacenia make us suspect the new 

genus of polyphylletic origin and we hesitate to 

accept it even as a section until we can find some 

correlating characters to support it. The character 

still remains a very good one to use in any type of 

key and it is good to have it brought to notice. 

On the other hand Menezes (1971a) and Noher 

and Cocucci (1971:268) are quite correct in their 

floral anatomical studies of Barbacenia, indicating 

that what Smith (1962:253, 271) considered a simple 

filament much dilated is a coronoid appendage to 

which the filament is fused. In fact this is macrcl 

scopically apparent in B. squamata Hooker and 

strikingly so in our new B. spiralis where the 32 mm 

long filament is completely free from the coronoid 

appendage. We are still unable to choose between 

Menezes' theory of a perianth origin of the coronoid 

appendages and Noher's of a staminoid. To prove 

I

their contentions, both cite dissolving technique 

producing continuous vascular traces yet neither 

publishes photographic evidence thereof. Perhaps 

it is as Carlquist (1969) states a matter of no great 

certainty. In Vellozia the appendages when present 

are always ventral to the stamens so it would seem 

reasonable to assume that they are stamina1 in 

origin until their structure can be verified. 

Leaf-blade anatomy is our most promising source 

of characters for correlation with the usual macroscopic system because of the availability of material, relative rapidity of technique, and variability 

among species, especially in Vellozia. Already we 

have been able to put it to use in defining a new 

section and redefining an old one in that genus and 

it is evident that further research will show more 

groupings of species. In our present keys we have 

used leaf-blade anatomy to show groupings of species or differences as opportunity offers. Even if 

complete couplets are unavailable now, there is a 

good chance of completing them later. 

So far the piece of leaf research awaiting exploitation is sheath anatomy. The morphology and 

anatomy of the leaf sheath in this family, so far as 

we are aware, is not quite understood. Preliminary 

examination of this tissue (Ayensu, 1968) has shown 

that some species exhibit a clear line of abscission 

between the leaf-blade and the sheathing, but other 

species do not show this character. Furthermore, 

the fiber of the sheath is divided into those with 

tightly parallel fibers with very little reticulate 

venation and those with few parallel fibers and 

highly pronounced reticulate venation. 

The stem anatomy of some species of the family 

has been studied in recent years by Ayensu (1968) 

and Menezes (1 97 1 a) and the general observations 

seem to correlate with the major character-states 

used in distinguishing Vellozia and Barbacenia 

sensu lato. Not many differences occur in Velloziaceae stems to be used in identifying specific species. 

The root anatomy of species of Barbaceniopsis 

has also been investigated by Ayensu (1968), but 

again not many specific characters could be assembled to identify individual species. 

The pollen morphology (using light, SEM and 

TEM techniques) has received much attention in 

recent years by Maguire (1969), Ayensu (1972, 1973), 

and Ayensu and Skvarla (1974). Essentially these 

studies show that the pollen morphology of Vellozia 

(united tetragonal tetrads) is strikingly different 

SMITHSONIAN CONTRIBUTIONS TO BOTANY 

from that of Barbacenia (monosulcate monads). 

Furthermore, inasmuch as some Vellozia species 

lend themselves to easy specific identification, Barbacenia species, on the other hand, are not easily 

identified at the specific level. 

It is hoped that future chromosomal studies will 

shed further light in our attempt to clearly define 

the species.

Excluded and Doubtful Taxa 

Barbacenia gracilis hortus ex Baker 

Barbacenia gracilis hortus ex Baker, Journ. Linn., 18:239, 

1880 [nomen]. 

This horticultural name was published in the 

synonymy of Dasylirion acrotrichum Zuccarini, a 

liliaceous species of Mexico. 

Barbacenia uaipanensis Maguire 

Barbacenia uaipanensis Maguire, Mem. N. Y. Bot. Gard., 

9:477, fig. 117, 1957. 

This species belongs in the Bromeliaceae. See 

Ayensua uaipanensis (Maguire) L. B. Smith (Mem. 

N.Y. Bot. Gard., 18(2):29, fig. 5A,B, 1969, and 

Ayensu, Mem. N.Y. Bot. Gard., 18(2):291-298). 

Velloria capsulis glabris, scapis hispidis Vandelli 

Velloria capsulis glabris, scapis hispidis Vandelli, F1. Lusit. 

& Brasil. Spec., 32, pl. 2, 1788. 

The above is interpreted as a polynomial because 

the words are separated from the description by a 

dash and the word for capsule is repeated; this 

would not occur if the final phrase were part of the 

description. The species was validated as Vellozia 

subscabra Mikan (Delect. F1. & Faun. Brasil., fasc. 

2, 1820) and named again as Vellozia scabra 

Sprengel (Syst. 3:338, 1826). However, the identity 

of the species remains a mystery because in nearly 

200 years of subsequent collecting in Minas Gerais 

there is yet to be found a Vellozia with a vestite 

scape and naked ovary, although Vandelli’s other 

species is well known. 

Vellozia coeru2escen.s hortus Belg. ex Gumbl. 

Vellozia coerulescens hortus Belg. ex Gumbl., Gard. Chron. 

for 1874, 2:623, 657, 1874. 
NUMBER 50 129 

According to Jackson (Index Kewensis 4: 1173, 

1895), this horticultural name is a synonym of 

Barbacenia purpurea Hooker. 

Velloxiu leptophylla Seubert 

Vellozia leptophylla Seubert in Martius, F1. Bras., 3(1):84, 

1847. 

This species was based on a sterile collection by 

Sellow without any indication of locality. 

Velloxiu mucrantha Lemaire 

Vellozia macrantha Lemaire, Ill. Hortic., 12(misc.):41, 1865. 

This species was placed in section Radia by L. B. 

Smith .(1962:268), but under our new and narrower 

interpretation it can scarcely remain in that section 

and its placement elsewhere seems very doubtful. 

Velloxiu scabra Sprengel 

Vellozia scabra Sprengel, Syst., 3:338, 1826. 

Unidentifiable, see under Vellozia capsulis glabris, 

scapis hispidis. 

Velloziu squamata auctt. ex Steudel 

Vellozia squamata auctt. ex Steudel, Nom. Bot. ed. 2, 2~746, 

1841 [nomen]. 

This name was published in the synonymy of 

Xerophyllum sabadilla, a Mexican liliaceous species 

of doubtful identity. It is scarcely more than evidence of a misdetermination. 

Velloxia subscabra Mikan 

Vellozia subscabra Mikan, Delect. F1. & Faun. Brasil., fasc. 

2, 1820. 

See under Vellozia capsulis glabris, scapis hispidis. 

Velloziu tomentosa Pohl 

Vellozia tomentosa Pohl, PI. Bras., 1:130, 1827. 

This species was described from sterile material 

collected between the crossing of the Rio Jequitinhonha and Calumbi, Minas Gerais, Brazil. It may 

be possible to identify it yet by leaf anatomy, in 

which case it may well antedate a name now in use.
