Var. novæ-zealandiæ.—Smaller and more slender, 1–5 in. high. Leaves ¼–½ in. long, oblong- or ovate-spathulate. Flowers smaller. G. novæ-zealandiæ, Armstr. in Trans. N.Z. Inst. iv. (1872) 290.
North Island: Base of Tongariro, Bidwill; Ruapehu, H. Hill! Kaimanawa Mountains, Tryon! Ruahine Range, Colenso! Tryon! Mount Egmont, Petrie! Tararua Mountains, Buchanan! South Island, Stewart Island: In various localities from Nelson southwards, but often local. Sea-level to 3500 ft. December–February.
This was reduced to Forster's G. montana by Sir J. D. Hooker; but Mr. N. E. Brown, who has recently done me the service of examining Forster's types preserved in the British Museum and at Kew, informs me that it is quite distinct, and in no way resembles G. montana. It may be recognised by the usually much-branched slender and wiry sparingly leafy stems, small rather thin leaves, small flowers terminal and solitary on the branches, and linear-subulate calyx-lobes.
4. G. chathamica, Cheesem. n. sp.—Annual, 6–12 in. high; main stem stout or slender, erect, with or without several shorter and weaker branches springing from the base and usually decumbent below. Radical leaves variable in size, ½–1¼ in. long, narrowed into short petioles or almost sessile, ovate-spathulate or oblong-spathulate to broadly oblong, obtuse, rather thin; cauline 1 or 2 pairs, ovate or oblong, sessile with a broad often almost cordate base. Flowers small, ⅓–½ in. long, white, sometimes vemed with pink, arranged in several 3–12-flowered umbels terminating the stem and its branches, each umbel with an involucre of 3–5 whorled bracts; pedicels usually longer than the bracts. Calyx about three-quarters the length of the corolla, divided about threequarters way down; lobes linear-oblong, obtuse. Corolla narrowcampanulate, divided two-thirds way down; lobes oblong or oblong-obovate. rounded at the tip. Ovary linear-oblong, sessile.—G. pleurogynoides var. umbellata. Kirk in Trans. N.Z. Inst. xxvii. (1895) 335.
Chatham Islands: Abundant in wet places. Travers! Miss Seddon! Cox and Cockayne!
I consider this to be a very distinct species, to be recognised without any difficulty by the peculiar habit, small and broad thin leaves, and small umbellate flowers, with a deeply divided calyx and corolla. A specimen collected by Mr. Buchanan at the Lindis Pass, Otago, and another gathered by Mr. H. B. Kirk on D'Urville Island may beiong to the same species, but they are far more copiously branched and have much longer leaves, and are best held over until more complete material is obtained.
5. G. corymbifera, T. Kirk in Trans. N.Z. Inst. xxvii. (1895) 336.—Usually perennial, but often dying after flowering. Root stout, long and tapering. Stems simple or rarely branched from the base, stout, erect, terete, 6–20 in. high. Radical leaves numerous, rosulate, 1–4 in. long, ¼–¾ in. broad, narrow oblong-spathulate or lanceolate-spathulate, obtuse or acute, narrowed into a short or long petiole, blade often channelled above, 1–3-nerved, coria-
