UMBELLIFERÆ.
Ligusticum.

broad decurrent bases, unequally 3–5-lobed; lobes acuminate, with acicular points and thickened margins; veins reticulate. Bracts very large, with broad concave bases 2–3 in. diam., and smaller foliaceous tips. Umbels numerous, compound, 2–3 in. diam., diœcious or polygamous; involucral bracts linear, acute. Flowers red. Fruit 1/6 in. long; carpels with 5 ridges, rarely with 4 or 3; vittæ solitary under each furrow.—Kirk, Students' Fl. 200. Anisotome latifolia, Hook. Fl. Antarct. i. 16, t. 8. Calosciadium latifoiium, Endl. ex. Walp. Ann. ii. 702.

Var. angustatum, Kirk, l.c.—Ultimate segments of the leaves narrower, ¼ in. wide or less, acicular points longer.

Auckland and Campbell Islands: Abundant in moist places throughout the group. December–January.

A noble species, said to occasionally reach the height of 6–8 ft.


2. L. antipodum, Homb. and Jacq. ex Dcne. Bot. Voy. Astrol. et Zél. 63, t. 3.—Stems 2–4 ft. high, very stout, deeply furrowed. Leaves 1–2 ft. long, coriaceous; petiole as thick as the thumb, sheathing at the base; blade oblong, 2–3 pinnate; ultimate segments very numerous, rigid, crowded, 1 in. long, 1/151/12 broad, linear-subulate, pungent-pointed. Bracts smaller and narrower than in L. latifolium. Umbels numerous, compound, 2 in. diam., diœcious or polygamous; involucral bracts narrow-linear. Flowers red. Fruit ¼ in. long, narrow-oblong; carpels one with 5 wings, the other 3-winged.—Hook. f. Handb. N.Z. Fl. 94; Kirk, Students Fl. 200. Anisotome antipoda, Hook. f. Fl. Antarct. i. 17, t. 9, 10. Calosciadium antipodum, Endl. ex Walp. Ann. ii. 702.

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. Leaves spreading, 2 ft. long or more, 6–9 in. broad, oblong or ovate-oblong, 3-pinnate; segments broad, acute, sharply toothed; petiole stout, finely grooved, the upper part of the sheath free, forming a ligule. Flowers not seen. Fruiting umbels 2–2½ in. diam., dense, compound; rays numerous, about 1 in. long. Fruit 1 in. long, exceeding the pedicels; carpels one 5-winged, the other 3-winged.—Kirk, Students' Fl. 201.

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.
