Tennyson, T.F.C.; Mount Torlesse, Haast! Petrie! T.F.C.; mountains by the upper and middle Waimakariri, Enys! Petrie! Cockayne! 3000–6000 ft. December–February.

A very remarkable plant, which cannot be confounded with any other found in New Zealand.


12. L. patulum, T. Kirk, Students Fl. 203.—Slender, greyish-green, 6–12 in. high or more. Stems erect or inclined, branched above, grooved. 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.


13. L. piliferum, Hook. f. Handb. N.Z. Fl. 96.—Stout, erect, glaucous-green, very aromatic. Root thick and tapering. Stem. 8–24 in. high or more, sparingly branched above, smooth, striate, purplish below. Leaves 4–16 in. long, very thick and coriaceous; petioles stout, sheathing, sheath long and narrow; blade linear or linear-oblong, pinnate; leaflets 8–12 pairs, ½–1 in. long, sessile, closely placed and often overlapping, deltoid-ovate or deltoid-orbicular, coarsely toothed or 2–3-lobed or pinnatifid; lobes or segments again toothed, tipped with a stout bristle. Umbels 2–4, on stout peduncles towards the top of the stem, 2–3 in. diam., compound, diœcious; rays ¾–1½ in. long, unequal; involucral bracts linear or lanceolate. Flowers white, rather small. Fruit 1/6 in. long, ovate-oblong; carpels usually 3-winged.—Kirk, Students' Fl. 204.

Var. a.—Leaflets broad, very coriaceous, usually deeply 3-lobed; the lobes broad, toothed.

Var. b, pinnatifidum, Kirk, l.c.—Leaflets longer and narrower, not so coriaceous, pinnatifidly cut into narrower lobes.

South Island: Not uncommon in mountain districts from Nelson to the west of Otago. 2500–4500 ft. December–January.


14. L. aromaticum, Hook. f. Handb. N.Z. Fl. 96.—Very aromatic, variable in size and habit, usually from 4–12 in. high, but in alpine situations often much dwarfed, matted and depressed, sometimes barely 2 in. high. Root stout, often long and tapering. Stem simple or sparingly branched above. Leaves all radical,
