Additions and Corrections
Order XXXIII. UMBELLIFERÆ.
Herbs, very rarely climbing or shrubby, often aromatic when bruised. Stems often grooved or channelled, solid or hollow. Leaves alternate, usually much cut and divided but sometimes simple and entire; petiole dilated and sheathing at the base; stipules wanting (except in Hydrocotyle). Flowers small, hermaphrodite or occasionally polygamous, in terminal or lateral umbels which are either simple or compound. Umbels usually furnished at the base with a ring of bracts, those below the primary (or general) umbel forming the involucre, those below the secondary (or partial) ones constituting the involucel. Calyx aduate to the ovary, limb either obsolete or 5-toothed. Petals 5, inserted at the margin of an epigynous disc, the outer often larger, imbricate or valvate, usually infiexed at the tip. Stamens 5, epigynous; filaments curved inwards. Disc epigynous, often 2-lobed and confluent with the base of the styles. Ovary inferior. 2-celled; styles 2, distinct; ovules 1 in each cell, pendulous. Fruit of 2 dry indehiscent carpels cohering by their inner faces (commissure), when ripe separatmg from a filiform central axis (carpophore), from the top of which they often remain suspended for a time. Each carpel (mericarp) generally bears 5 longitudinal ridges, sometimes expanded into wings. In the spaces or furrows between the ridges, and imbedded in the pericarp, are one or more longitudinal oil-canals (vittæ). Secondary ridges are also sometimes placed between the primary ones. Seeds 1 to each carpel, pendulous; albumen abundant, horny; embryo minute, next the hilum, radicle superior.
A very large and extremely distinct order, represented all over the world, but most plentiful in western Asia, south Europe, and north Africa; rarer in the tropics and in the south temperate zone. Genera about 160; species estimated at 1500. The properties of the order are extremely varied. Several species secrete a poisonous and narcotic acrid sap, as hemlock, fool's parsley, water drop-wort, &c. Others are characterized ty the presence of a gum-resin, as Asafœtida and Galbanum. Many species produce aromatic and carminative fruits, as caraway, coriander, dill, &c. The chief edible species are the carrot and parsnip, where the roots alone are eaten; and celery, parsley, and fennel, where the leaves and stems are employed. Of the 11 New Zealand genera, Aciphylla and Actinotus extend to Australia; Azorella and Oreomyrrhis occur in South America and the Antarctic islands as well. The remaining 7 are all widely distributed.

North and South Islands, Stewart Island: Abundant throughout, var. montana ascending to quite 4,000 ft. Var. robusta: Sandy beaches north of Auckland, rare. November–March.
A very variable plant, but one that can generally be recognised without much difficulty by the shallow and rounded lobes of the leaves, and by the compressed fruits with thick obtuse margins. I am unable to maintain Mr. Kirk's H. robusta as a separate species, the differences between it and the typical state being of a very trivial character. Closely allied to it is a large-leaved species gathered by Mr. Cockayne in forests in the Chatham Islands, in which the leaves are sometimes 2 in. diam.

Kermadec Islands, North and South Islands, Chatham Islands: Abundant throughout, ascending to 2000 ft. November–March.
Closely allied to H. novæ-zealandiæ, but separated by the distinctly lobed leaves, by the lobes being acutely toothed, and by the much smaller crowded fruits, which are sharply keeled on the back.
8. H. microphylla, A. Cunn. Precur. n. 496.—Glabrous or with a few loose hairs on the petioles and peduncles. Stems 1–3 in. long, slender or rather stout at the base, creeping and rooting, often matted.

Peduncles variable in length, longer or shorter than the leaves; umbels 2–6-flowered. Flowers sessile or nearly so. Fruit minute, glabrous, 1/20–1/15 diam.; carpels rounded at the back, with an obscure rib or groove on each face.—Hook. f. Fl. Nov. Zel. i. 84; Handb. N.Z. Fl. 87; Kirk, Students Fl. 190.
North and South Islands, Stewart Island: From Mongonui southwards, but apparently local. December–February.
Cunningham's original description is not at all good, and without access to his specimens I cannot be certain that the plant described above is the same as his. It differs from H. novæ-zealandiæ in the smaller size, glabrous and more deeply divided leaves, few-flowered umbels, and smaller fruit. From H. moschata it is at once removed by the round-edged carpels.
9. H. asiatica, Linn. Sp. Plant. 234.—Very variable in size. Stems rather stout, much branched, creeping and rootmg at the nodes. Leaves fascicled at the nodes, ¼–1 in. diam., orbicular or oblong-reniform, cordate or almost truncate at the base, sinuatetoothed or nearly entire, glabrous or slightly pubescent; petioles very variable in length, ½–6 in. or more, often laxly pubescent above. Peduncles short, ¼–1 in. long, rarely more; umbels 2–4-flowered; bracts 2–3, broad, ovate. Fruit 1/8–1/6 in. diam.; carpels with about 3 stout ribs on each face, but often showing the secondary ribs when young, somewhat reticulated, margins obtuse.—A. Cunn. Precur. n. 502; Raoul, Choix, 46; Hook. f. Fl. Nov. Zel. ​i. 82; Handb. N.Z. Fl. 86; Benth. Fl. Austral. iii. 346; Kirk, Students' Fl. 190. H. cordifolia, Hook. f. Ic. Plant. t. 303. H. uniflora, Col. in Trans. N.Z. Inst. xvii. (1885) 239.
North and South Islands, Stewart Island, Chatham Islands: Abundant in moist places from the Three Kings Islands and the North Cape southwards, ascending to 2500 ft. October–March. Also in most tropical and subtropical countries.
2. AZORELLA, Lam.

Disc thick, flat, often confluent with the styles. Fruit but slightly laterally compressed, almost tetragonous, the sides furrowed at the commissure when mature. Carpels subterete or dorsally compressed, with 5 more or less prominent and almost equidistant ribs, the lateral ones not close to the commissure.

North Island: Ruahine Mountains, A. Hamilton! South Island: Not uncommon in mountain districts from Nelson to Otago, altitude 2000–5000 ft. December–February.
This varies much in most of its characters, and as a species is doubtfully distinct from A. reniformis. Ordinarily, however, it can be separated from that plant by the ciliate stipules, many-flowered umbels, and long fruiting pedicels. But the stipules are sometimes entire, and dwarf specimens frequently have short pedicels. Mr. Colenso's Pozoa elegans (as proved by the type specimens in his herbarium, labelled in his own handwriting) is founded upon the tips of the flowering shoots of A. Haastii. He describes the leaves as "2–3-foliolate," having evidently mistaken the approximate floral leaves for parts of a compound leaf.
5. A. Roughii, Benth. and Hook. f. l.c.—Perfectly glabrous, smooth and shining. Rhizome stout, branched, terminated by numerous radical leaves, and usually with prostrate or ascending leafy flowering branches. Leaves ½–1½in. diam., orbicular or reniform, coriaceous, 3–5-foliolate or -partite; leaflets sessile, broadly obcuneate, deeply crenate-toothed or lobed at the tip; lobes rounded; petioles 1–6 in. long; stipules usually laciniate. Flowering shoots often exceeding the leaves; umbels many-flowered, usually 1–3 secondary ones arising from the base of the primary and overtopping it; involucral bracts linear-oblong, obtuse. Pedicels usually longer than the linear-oblong fruit; carpels rounded at the back, 5-ribbed.—Kirk, Students' Fl. 192. Pozoa Roughii, Hook. f. Handb. N.Z. Fl. 89.
South Island: Mountains of Nelson and Marlborough, from Dun Mountain to the Upper Clarence and Waiau, not uncommon. 2500–5000 ft. December–February.
This has the same habit as A. Haastii, but can always be recognised by the divided leaves. I have seen no specimens from the south of Lake Tennyson and the Upper Waiau.
​6. A. hydrocotyloides, Benth. and Hook. f. l.c.—Perfectly glabrous, stout, often densely matted. Root long and woody. Stems creeping and rooting at the nodes and putting up tufts of leaves, the runners sometimes 6 in. long or more. Leaves numerous, crowded, ¼–⅔ in. diam., orbicular or orbicular-reniform, very thick and coriaceous, 3–5-foliolate or -partite; leaflets sessile, sometimes overlapping, broadly obovate-cuneate, bluntly 3–5-lobed or -crenate at the tip; margins thickened; petioles stout, ½–1½ in. long; stipules narrow, entire or ciliate. Peduncles variable in length, solitary from the nodes of the stem or 2–4 at the top of a leaf-bearing scion. Umbels 4–15-flowered; involucral bracts linear, obtuse. Fruit linear-oblong, tetragonous, usually shorter than the pedicel; carpels 5-ribbed.—Kirk, Students' Fl. 192. Pozoa hydrocotyloides, Hook. f. Handb. N.Z. Fl. 88.

A genus of 5 or 6 species, all of which are natives of America, from Mexico to the Falkland Islands, one of them extending to Australia and New Zealand.
1. O. andicola, Endl. Gen. Plant. 787.—Exceedingly variable in stature and habit, 2–24 in. high, either stemless with radical leaves and scapes or much branched from the base, with short or long slender sparingly divided leafy stems, glabrescent or tomentose or pilose. Leaves usually numerous, mostly radical, 1–6 in. long, linear-oblong, pinnate or 2-pinnate; leaflets pinnatifid or variously toothed or incised. Peduncles several, usually springing from the rootstocks, but in the branched varieties axillary as well, longer or shorter than the leaves, glabrescent or pilose, especially towards the tip, where the hairs are usually reversed. Umbels few- or many-flowered; involucral bracts 6–8, ovate to linear. Flowers at first sessile, but pedicels lengthening as the fruit ripens, often unequally so. Fruit linear- or ovate-oblong, glabrous or more or less densely pubescent.—Hook. f. Fl. Antarct. ii. 288, t. 101; Benth. Fl. Austral. iii. 377; Kirk, Students' Fl. 197.

I have followed Mr. Bentham and the "Index Kewensis" in uniting the three New Zealand species described by Hooker with the American and Australian O. andicola. Any large series of specimens will show that the development or non-development of a branched stem, and the amount of pubescence, which were the characters relied upon for the separation of the species, are in Oreomyrrhis far too variable and inconstant to be employed for that purpose.

South Island: Otago—Hector's Col, near Mount Aspiring, Buchanan; Mount Kyehnrn, H. J. Matthews! 4000–5000 ft. January–February.
Mr. Kirk reduced this to A. Lyallii in the "Students' Flora," but it differs from that species in the trifoliolate leaves, and in the leaflets at the top of the leaf-sheath being almost as long as the leaves proper, whereas they do not reach the base of the lowest pinnule in A. Lyallii. It is much nearer to A. Traillii which may be a depauperated state of it.
7. A. Traillii, T. Kirk in Trans. N.Z. Inst. xvi. (1884) 371.—Small, 3–7 in. high, clothed below with the bases of the old leaves. Leaves 2–4 in. long, simple or 3-foliolate, or rarely pinnate with 2 pairs of leaflets and a terminal one; leaflets 1–3 in. long, 1/12–1/8 in. ​broad, narrow-linear, pungent-pointed, rigid and coriaceous when dry, striate, margins thickened; petiole short, sheath narrow, rather membranous. Scape slender; bracts long, with broad membranous sheaths and a long simple or 3-partite pungent leaflet at the top. Male umbels distant or crowded, on short peduncles or almost sessile; females much smaller, concealed in the tumid sheaths of the bracts. Fruit linear-oblong, 1/10–1/8 in. long; carpels 5-ribbed. Vittæ 1 or rarely 2 in the interspaces, 2 or 4 on the commissural face.—Students' Fl. 210.
South Island: Otago—Mount Ida and Mount Kyeburn, Petrie! Stewart Island: Mounts Anglem and Rakiahua, Kirk! Goyen! 2000–3500 ft. December–January.
Not far removed from A. Lyallii, but smaller in all its parts, and with the leaves simple or 3-foliolate, rarely pinnate. Still more closely allied to A. Hectori.
8. A. Kirkii, Buch. in Trans. N.Z. Inst. xix. (1887) 214, t. 17.—Stout, erect, smooth and polished, 6–12 in. high. Leaves all radical, yellowish-brown, 4–9 in. long, ¼–½ in. broad or more, simple or forked or 3-foliolate, excessively thick and coriaceous, striate, suddenly narrowed into a short spinous point; sheath short and narrow, jointed at its junction with the blade. Flowering scape stout, naked below, grooved. Bracts coriaceous, spinous, simple or 2–3-partite. Male umbels shortly peduncled; females almost sessile in the axils of the bracts, crowded, forming a dense spicate inflorescence 2–3 in. long. Fruit linear-oblong, 1/5 in. long; carpels 4–5-winged. Vittæ 1–2 in the interspaces, 4 on the commissural face.—Kirk, Students' Fl. 209.
South Island: Otago—Mount Alta, Buchanan! Hector Mountains, hill near Mount Aspiring, Petrie! 5000–6000 ft. January.

Radical leaves numerous, 3–9 in. long, pinnate or 2-pinnate below; leaflets 2–6 pairs, ½–2 in. long, 1/12–1/4 in. wide, linear, pungent, rigid and coriaceous, striate; sheaths long and narrow, membranous or flaccid, with two subulate leaflets at the top. Umbels compound, forming an open branched panicle 1½–4in. long. Bracts spreading, sheaths often broad and membranous, tipped by a pinnately divided leaflet. Peduncles of the male umbels ½–2 in. long, females about half the length; rays numerous, slender, spreading; involucral bracts linear. Fruit 1/6 in. long, linear-oblong; carpels 5-winged or rarely 4-winged. Vittæ 1–2 in the interspaces, 2–4 on the commissural face.—Handb. N.Z. Fl. 93; Kirk, Students Fl. 210.}}
South Island: Abundant in mountain districts throughout. 3000–6500 ft. December–January.
A variable plant. The leaves are sometimes uniformly 1-pinnate with rather broad leaflets, at other times 2-pinnate at the base with narrower leaflets. The female umbels are usually paniculate, but occasionally the panicle is somewhat contracted, showing an approach to that of A. Lyallii.
10. A. polita, Cheesem.—Stems erect, 3–12 in. high, clothed at the base with the sheaths of the old leaves. Radical leaves numerous, very slender, firm but hardly coriaceous, 2–6 in. long or more, 2–3-pinnate; primary divisions 4–6 pairs; ultimate segments very narrow-linear, almost capillary, not more than 1/30 in. broad, mucronate but hardly pungent; petiole as long as the blade, sheath broad, membranous, produced at the tip into 2 almost filiform leaflets. Umbels compound, forming a loose open panicle, female slightly more contracted than the male. Bracts with a broad sheathing base, tipped with a pinnately divided leaflet. Male peduncles ½–1½ in. long, female ⅓–¾ in.; involucral bracts subulate-lanceolate. Pedicels short. Flowers white.

Very closely allied to A. Monroi, but much more slender, and with less coriaceous almost membranous leaves, which are much more finely divided, the segments being sometimes nearly capillary. Mr. Kirk referred it to Ligusticum in the "Students' Flora," but it must certainly remain in the neighbourhood of A. Monroi.
11. A. Dobsoni, Hook. f. Handb. N.Z. Fl. 93.—Stout, smooth and shining, forming compact yellowish-brown patches 3–6 in. diam. Rootstock thick and woody, branched at the top. Leaves all radical, very numerous, densely imbricated, excessively thick and coriaceous, 1½–3 in. long; sheaths ½–1½ in. or more, ¾ in. broad; leaflets 3 at the top of the sheath, about equal, 1–2 in. long, ⅓ in. broad at the base, linear-subulate or dagger-shaped, rigid, concave, transversely jointed, keeled at the back towards the top, pungent-pointed. Flowering-stem very stout, almost as thick as the little finger, grooved. Umbels 4–5, clustered at the top of the stem, forming a capitate inflorescence; peduncles short, thick. Fruiting umbels densely packed, forming a rounded head 1 in. in diam. or more. Fruit linear-oblong, 1/8 in. long; carpels 4–5-winged, but not seen quite ripe.—Kirk, Students' Fl. 210.

A most remarkable plant, nowhere plentiful, and seldom seen in flower or fruit.
​12. A. simplex, Petrie in Trans. N.Z. Inst. xxii. (1890) 440.—Very similar to A. Dobsoni, and with precisely the same habit, but differing in the leaves, which are less coriaceous and quite entire, l½–3 in. long; lower half expanded into a broad sheath; blade linear-subulate, rigid and coriaceous, concave above, obtusely rounded at the tip with a short pungent mucro, transversely jointed and often longitudinally grooved, midrib usually evident, margins thickened. Flowering-stem stout, 1½–3 in. long; umbels and flowers as in A. Dobsoni. Ripe fruit not seen.—Kirk, Students' Fl. 211.
South Island: Otago—Mounts Pisa and Cardrona, and the Hector Mountains, Petrie! 5000–6000 ft. February.
13. A. Dieffenbachii, Kirk, Students' Fl. 211.—Stem stout, erect, 2–3 ft. high, 1–1½ in. diam. at the base, grooved.

Peduncles 2–5 in. long; rays of the male umbels numerous, slender, of the females about 6; involucral bracts few, linear-subulate. Fruit large, 5/8 in. long, 3/8 in. broad, broadly oblong, much dorsally compressed; carpels one 3-winged and the other 2-winged, rarely both 3-winged. Vittæ 1 in each interspace and 2 on the commissural face.—Ligusticum Dieffenbachii, Hook. f. Handb. N.Z. Fl. 729. Gingidium Dieffenbachii, F. Muell. Veg. Chath. Is. 17, t. 1.
Chatham Islands: Rare, H. H. Travers! F. A. D. Cox!
The fruit of this is quite unlike that of Aciphylla, Ligusticum, or Angelica, to all of which genera it has been referred. Mr. Kirk is probably correct in considering that it will ultimately form the type of a new genus.
9. LIGUSTICUM, Linn.
Perennial herbs, often large and stout, usually with aromatic or strong-smelling foliage or roots. Leaves 1–2–3-pinnate or ternately divided; rhachis articulated at the insertion of the leaflets. Umbels compound, rarely simple, usually of many rays; involucral bracts few or many, sometimes wanting. Flowers white or red, polygamous or diœcious. Calyx-teeth small or obsolete. Petals incurved at the tip. Fruit linear-oblong, oblong, or ovate-oblong; carpels rounded or dorsally compressed, each with 5 equal narrowly winged ridges, or one carpel 5–4-winged, the other 4–3-winged. Vittæ usually numerous in the interspaces in the northern species, seldom more than 1 in each interspace in the southern.
A genus of from 30 to 40 species, widely distributed throughout the Northern Hemisphere, in the Southern Hemisphere confined to New Zealand, with the exception of a few species found in South America and one in Australia. All the New Zealand species are endemic.

Auckland and Campbell Islands, Antipodes Island: Abundant throughout the group, Sir J. D. Hooker, Kirk! December–January.
Almost as fine a plant as the preceding, which is its nearest ally, and from which it is easily separated by the finely divided leave with numerous linear segments.
3. L. acutifolium, T. Kirk in Journ. Bot. (1891) 237.—Stems 3–5 ft. high, stout, deeply furrowed; rootstock as thick as the wrist.

The Snares: Not uncommon, Kirk! December.
My knowledge of this plant is derived from a single imperfect specimen in Mr. Kirk's herbarium, and in default of further information I have reproduced the description given in the "Students' Flora." It is evidently very close to L. intermedium, but according to Kirk can be distinguished by the ligulate petiole, acute segments of the leaves, smaller umbels and shorter fruits, and by the absence of viscid milky juice.
​4. L. intermedium, Hook. f. Handb. N.Z. Fl. 94.—Stems rather stout, 6–24 in. high, abounding in viscid milky juice. Leaves 6–20 in. long; petiole long, stout, sheathing at the base, with narrow membranous wings; blade coriaceous, oblong to ovate-oblong, 2–3-pinnate; primary divisions 5–8 pairs, 2–4 in. long; leaflets ½–1¼ in. long, rather broad, ovate-triangular, cuneate at the base, sessile or shortly stalked, unequally cut to the middle or below it into broad-linear obtuse or subacute lobes.

South Island: Sounds of the south-west coast, Lyall, Hector and Buchanan! G. M. Thomson! December–January.
This only differs from L. intermedium in the slightly larger size and more finely divided leaves, and might well be regarded as a variety.

Umbel solitary, compound, large for the size of the plant. 1½–4 in. diam.; involucral bracts about 5, 2–3-ternately divided like the leaves, overtopping the umbel; rays numerous, rigid, almost woody in fruit, ½–1 in. long. Secondary umbels small, concealed among the bracts of the involucels, which far exceed the small white or pink almost sessile flowers. Calyx-teeth acute, prominent. Styles rigid, subulate. Fruit oblong, ¼ in. long; carpels incurved, with 5 low obtuse ridges, commissural face rounded; vittse 1 under each furrow and 2 on the commissure.—Kirk, Students' Fl. 203.

Radical leaves 2–6 in. long, linear-oblong in outline, pinnate or rarely 2-pinnate; leaflets 4–7 pairs, cut down to the rhachis into narrow-linear acute lobes, which are again toothed or incised at the tips, rarely entire. Cauline leaves smaller, with fewer leaflets and narrower lobes. Umbels small, simple in the very imperfect specimens seen, on slender peduncles, 6–12-flowered; involucral bracts linear, with a broad base, usually shorter than the unequal pedicels. Ripe fruit not seen.
South Island: Canterbury—Limestone cliffs near Burke's Pass, J. B. Armstrong! Otago (?) Buchanan!
There is a fragmentary specimen of this species in Mr. Kirk's herbarium, and another (without locality) in Mr. Buchanan's. The material is far too incomplete to form the basis of a satisfactory diagnosis; and that given above will doubtless require amendment when a good series of specimens is obtained.

5. A. rosaefolia, Hook. Ic. Plant. t. 581.—Stems 2–5 ft. long, much branched, scrambling over rocks or among bushes, hard and almost woody below, clothed with the persistent sheaths of the old leaves. Leaves cauline, alternate, 2–5 in. long, pinnate; leaflets 2–5 pairs, 1–2½ in. long, opposite, sessile, ovate or ovate-oblong to ovate-lanceolate, often oblique at the base, acute, finely serrate, submembranous or coriaceous, veins reticulated; petiole slender, rigid; sheaths broad, membranous, 2-lobed at the top.

Ruahine Range, Harding! Upper Rangitikei, Buchanan! South Island: Akaroa, Raoul.' Sea-level to 2000 ft. Koherika; Kohepiro. October–November.
This and the preceding species are anomalous in the order from their subscandent stems. The leaflets are furnished with a pair of minute stipellæ at the base—one on the upper surface, the other below.
11. DAUCUS, Linn.
Annual or biennial herbs, usually hispid. Leaves decompound, ultimate segments narrow. Umbels compound; rays numerous; bracts of the general involucre usually pinnatisect. Flowers white. Calyx-teeth small or obsolete. Petals often unequal, inflexed at the tips.

North and South Islands, Chatham Islands: Abundant in lowland districts throughout. October–December.
The allied D. carota, L., the origin of the cultivated carrot, has become naturalised in several localities in both islands. It can be distinguished from D. brachiatus by its greater size, broader leaf-segments, and much larger compact flat-topped umbels.
