1. G. Lyallii, Hook. f. Fl. Nov. Zel. i. 137.—Stems 1–2 ft. high, stout, branched, decumbent or prostrate at the woody base, then erect, cottony above. Leaves close-set or the upper remote, spreading, 2–4 in. long, ¼–¾ in. broad, narrow oblong-lanceolate or narrow obovate-lanceolate, acute, gradually narrowed to a sessile base, membranous, glabrous above, beneath clothed with thinly appressed white tomentum and distinctly 3-nerved, Heads rather large, ½ in. diam., disposed in many-flowered terminal corymbs 2–4 in. across; pedicels cottony. Involucral bracts numerous, scarious, white, radiating, with short woolly claws. Female florets very numerous, disc-florets much fewer. Achene linear-oblong, smooth, glabrous. Pappus-hairs few, very slender.—Handb. N.Z. Fl. 152; Kirk, Students' Fl. 297. G. adhærens, Col. in Trans. N.Z. Inst. xvii. (1885) 244.
North Island: Ruahine Range, Colenso! Andrew, Hewlett! Murimotu and Moawhango, Petrie! Rimutaka Range, Kirk! South Island: Not uncommon along the western side from Collingwood to the Otira Gorge and southwards to Milford Sound. Sea-level to 2500 ft. November–January.
A handsome plant, in its usual state at once recognised by the large size, broad distinctly 3-nerved leaves, and large heads. But small states with narrower leaves and smaller heads are difficult to separate from G. Keriense, and there is little doubt that the two species pass into one another. In both G. Lyallii and Keriense the disc florets are frequently sterile, showing a tendency in the heads to become unisexual.
2. G. trinerve, Forst. Prodr. n. 289.—Stems 1–2 ft. long, rather slender, sparingly branched, prostrate or decumbent, glabrate below, more or less white and cottony above. Leaves distant, spreading or deflexed, ½–1 in. long, obovate-lanceolate or spathulate, broadest towards the tip, acute or apiculate, gradually narrowed to a broad base, glabrous above and faintly 3-nerved, white with appressed wool beneath. Heads in corymbs of 3 to 10 or solitary, terminating the branches, which are produced into slender cottony bracteate peduncles, ½–¾ in. diam. Involucral bracts numerous, white, radiating, the outer woolly at the base. Achene linearoblong, glabrous. Pappus-hairs few, slender.—A. Rich. Fl. Nouv. Zel. 239; A. Cunn. Precur. n. 455; Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 138; Handb. N.Z. Fl. i. 153; Kirk, Students Fl. 297.
North Island: Rimutaka Range, Kirk! South Island: West coast of Nelson to Westland and INIilford Sound, south and east coasts of Otago; not uncommon. Sea-level to 2000 ft. November–December.
Closely allied to the preceding, but sufficiently characterized by the more slender stems, shorter obovate-spathulate leaves, which are seldom 3-nerved beneath, and by the bracteate peduncles.
3. G. Keriense, A. Cunn. Precur. n. 454.—Stems short or long, prostrate or decumbent, with numerous erect or ascending leafy branches 3–9 in. long, cottony above. Leaves spreading,
