1. N. depressa, Banks and Sol. ex Gærtn. Fruct. i. 124, t. 26.—A slender glabrous perennial, very variable in size, often forming broad matted patches; stems 2—12 in. long, creeping and rooting at the nodes.

Austral. iii. 431; Kirk, Students' Fl. 246. N. montana. Col. in Trans. N.Z. Inst. xxviii. (1896) 595.

North Island: Ruahine Range, Colenso. South Island, Stewart Island, Auckland Islands: Abundant throughout, chiefly in mountain districts. Ascends to 4000 ft. October–January.

Also found in Australia and Tasmania, South America, and Tristan d'Acunha. The leaves very rarely have a few sparse hairs on the upper surface.


2. N. Cunninghamii, Hook. f. Fl. Nov. Zel. i. 112.—Perfectly glabrous. Stems much more slender than in N. depressa, almost filiform, 4–18 in. long. Leaves ¼–⅓ in. long, narrow-ovate, acute, rounded at the base; petioles about as long as the blade. Stipules small, acute. Flowers very minute, terminal. Calyx-limb truncate or obsoletely 4-toothed. Corolla shorter and broader than in N. depressa, 1/12 in. long, 4-lobed. Stamens usually erect. Drupe globose, red, 1/8 in. diam.—Handb. N.Z. Fl. 120; Kirk, Students Fl. 247. ?N. papulosa, Col. in Trans. N.Z. Inst. xxviii. (1896) 595.

North Island: Mongonui and Kaitaia southwards to Cook Strait, but often local. South Island: Near Westport, Townson! October–January.

This differs from the preceding species only in the more slender habit, narrower leaves, and slightly smaller drupe. It is said to occur in the Philippine Islands.
