A beautiful little plant, probably not uncommon in moist peaty situations, but very easily overlooked.

Leaves numerous, crowded, rosulate, ⅓–¾ in. long; blade ⅛–⅓ in., spathulate or obovate or orbicular-obovate, narrowed into a broad and flat petiole of varying length, upper surface and margins covered with glandular hairs; stipules scarious, narrow, laciniate.

North and South Islands, Stewart Island: From Mongonui southwards, but often local. Sea-level to 4500 ft. November–January. Also in Australia and Tasmania.

Mountain specimens are often much reduced in size, with shorter and broader leaves, 1–2-flowered scapes, and broader calyx-lobes; but they pass by insensible gradations into the ordinary form.

D. binata, Labill Nov. Holl. Pl. i. 78, t. 105, f. 1.—Stemless. Rootstock short, emitting numerous fleshy roots. Leaves all radical, erect; petioles 2–5 in. long, slender, glabrous; blade 2–4 in., divided to the base into 2 narrow-linear segments 1/15–1/10 in. broad, which are simple or again forked, upper surface and margins clothed with long glandular hairs.

Calyx deeply 4–5-lobed; lobes oblong, entire or lacerate at the tips. Petals 4–5, obovate, twice as long as the calyx. Styles usually 3, penicillate.—Bot. Mag. t. 3082; Hook. f. Fl. Nov.

North and South Islands, Stewart Island: From the North Cape southwards. Sea-level to 2500 ft. November–February. A common Australian and Tasmanian plant.

A very handsome and conspicuous species. Mr. Colenso's D. flagellifera, as shown by the specimens in his herbarium, is merely a small state with narrower and often simple leaf-segments, and can be matched in any locality where the plant is plentiful.

D. auriculata, Backh. ex Planch, in Ann. Sci. Nat. Ser. 3, ix. (1848) 295.—Rootstock slender, terminating in a globose tuber deep page 147in the ground. Stems leafy, erect, flexuose and wiry, simple or sparingly branched, perfectly glabrous, usually 6–18 in. high but sometimes much longer and almost climbing. Radical leaves rosulate, sometimes reduced to linear scales; blade orbicular or reniform, glandular; petiole short, broad, flat. Cauline leaves alternate, on longer filiform petioles, peltate; blade ¼ in. diam., broadly lunate, the two angles with glandular-ciliate appendages, margins fringed with long glandular hairs.

Styles 3, divided to below the middle into numerous dichotomous lobes.—Hook. f. Fl. Nov. Zel. i. 21; Handb. N.Z. Fl. 64; Benth. Fl. Austral. ii. 465; Kirk, Students' Fl. 146.
