Leaves mostly cauline, few, small, ⅙–⅓ in. long, oblong- or obovate-spathulate, obtuse or subacute, sessile or the lower ones narrowed into short flat petioles. Flowers solitary, terminating the branches, large for the size of the plant, ⅓. in diam., white. Calyx broad, tube ⅛ in. long; lobes ⅕ in., broadly ovate, acute. Corolla subrotate, divided about ½-way down; lobes ovate, subacute. Stamens more than ½ as long as the corolla; anthers oblong. Ovary linear-obovoid.

South Island: Nelson—Slopes of Mount Arthur, 4000–5000 ft., T.F.C. January.


2. G. lineata, T. Kirk in Trans. N.Z. Inst. xxvii. (1895) 334, t. 27.—A small densely tufted perennial herb 2–4 in. high, often forming a compact sward; rootstock branched above. Leaves all radical or crowded on very short branches, erect, ½–¾ in. long, 1/251/15 in. broad, linear or narrow linear-spathul ate, acute or obtuse, gradually narrowed into a slender flat petiole, sheathing at the base. Scapes 1–3 in. long, slender, wiry, erect, naked or with 1 or 2 pairs of linear leaves at the very base. Flower solitary, ½–⅔ in. long. Calyx-tube 1/10 in. long; lobes 3/10 in., linear-subulate, tapering to an acute or almost acuminate tip. Corolla narrow-campanuiate, cut down ⅔ of the way to the base into 5 ovate acute lobes. Stamens ⅔ as long as the corolla.

South Island: Otago—Crest of the Longwood Range, Kirk! Blue Mountains, Petrie! Stewart Island: Exact locality not stated, Petrie! Sea-level to 3500 ft. January–March.

A curious little plant, easily recognised by the peculiar habit, very narrow leaves, and naked scapes bearing a rather large solitary flower.


3. G. Griselbachii, Hook. f. in Hook. Ic. Plant. t. 636.—A slender much or sparingly branched annual herb; root weak, often filiform; stems branching from the base, very slender, decumbent or subei-ect, 3–14 in. long, rarely more. Lower leaves narrowed into slender petioles as long or longer than the blade, ½–1 in. long, spathulate or oblong-spathulate, rather thin and membranous, obtuse; cauline usually smaller, remote, sessile or shortly petiolate, oblong or ovate-oblong, obtuse or subacute. Flowers few or many, terminal and solitary at the tips of the branches, rather small, ⅓–⅔ in. long, white. Calyx divided ¾-way down or more, often somewhat angled at the base; lobes linear or linear-subulate, acuminate, midrib distinct. Corolla narrow-campanuiate, divided more than ½-way down; lobes narrow-ovate or oblong, acute. Stamens about two-thirds the length of the corolla. Ovary linear-oblong, often shortly stipitate.—G. montana, Hook. f. Fl. Nov. Zel. i. 178; Handb. N.Z. Fl. 190 (not of Forst.).
