Blumea 55 (1): 91-93, 2010: “Small rhizomatous herb up to c. 5 cm high, most parts hairy and scattered with two types of minute glandular hairs, one brownish and the other dark purple or black, the latter type especially abundant on the rhizome, petiole and peduncle. Rhizome slender, elongated, c. 1 mm diam (in sicco); stipules triangular to narrowly triangular or narrowly triangular-ovate, 2–3 mm long, with an acute to long acuminate apex and some cilia along the margin of the apical part. Leaves peltate; petiole inserted at 0.5–4 mm from the nearest margin, 12–48 mm long; leaf blade asymmetric or slightly so, narrowly ovate to very narrowly elliptic-ovate, 20–48 by 4–17 mm, with a long acuminate to attenuate apex, with 3–6 palmate main nerves; margin finely dentate, the teeth ending in a hair; upper surface concolorous, bullate with small bullae in compound groups, each topped with a hair, nerves not prominent; lower surface with slightly prominent main nerves (in sicco), all nerves set with patent hairs. Inflorescence axillary, a contracted, cincinnal monochasium consisting of 1 or 2 male and 1 terminal female flower; peduncle simple, 20–37 mm long; bracts 2 or 3, broadly ovate, 1–1.5 mm long, with a ciliate margin. Male flower erect; pedicel 9–15 mm long; perianth segments 2, circular to broadly elliptic, 5–8 by 4–6 mm, yellow, glabrous except for some minute glandular hairs; androecium a zygomorphic fascicle with 7–11 stamens in several rows like an amphitheatre; filaments fused at base into a short column of c. 0.5 mm, free parts 0.2–1 mm long; anthers c. 1 mm long, opening by 2 unilateral longitudinal slits. Female flower: similar to the male one but pedicel elongated in fruit up to 4 mm; styles 4, 1.7–2.2 mm long, fused at base, stigma terminal, semicircular, not coiled; ovary narrowly elliptic to oblong, 6–8 by 1–1.2 mm including the 1–2 mm long beak, 4-locular, with 4 very narrow ribbon-like wings all along. Infructescence: peduncle straight; fruit erect, narrowly elliptic to oblong, 5–10 by 1–1.5 mm including the 1.5–4 mm long beak, thin-walled.
