Descriptions

General Description

A terrestrial, occasionally epiphytic herb 12–21(–26) cm. high, glabrous except for the lip; roots smooth, fleshy, white, 3–5 mm. broad. Stem climbing. Pseudobulbs superposed, ± fusiform, attenuate towards apex, 7.5–11 cm. long, the widest part 5–8 mm. broad, 2–3-leaved, enclosed when young by several scarious, straw-coloured, tubular ovate-elliptic, acute, evanescent sheaths. Leaves narrowly elliptic or ovate-elliptic, acute; lamina (6–)8–11 cm. long, 2.5–4.5 cm. broad, green; petiole irregularly articulated, shorter than the lamina, 2–6 cm. long. Inflorescence erect, paniculate, compact, (6–)8–14 cm. long, 2–3 cm. broad, many-flowered, lax or subdense; lowermost bracts ovate-elliptic to narrowly elliptic; uppermost linear-subulate, acute, 4–7(–15) mm. long. Flowers small; sepals and petals white, sometimes flushed green; lip white, with a few purple nerves and a purple throat; column with a few purple flecks; pedicel and ovary 6–13 mm. long. Dorsal sepal oblong, ± acute, 3-nerved, 6.5–8.5 mm. long, 2 mm. broad; lateral sepals oblong or narrowly oblanceolate, acute, slightly carinate at apex, 3-nerved, 7–8(–9) mm. long, 2–2.5 mm. broad. Petals oblong-elliptic, mucronate, 3-nerved, 6–7.8 mm. long, 1.5–2.3 mm. broad. Lip not articulated at the base, distinctly 3-lobed, with very short hairs at the spur-entrance and along the nerves, otherwise glabrous, 7–8 mm. long, 4.3–6.2 mm. broad; mid-lobe truncate, emarginate or divided into 2 very short lobules, broadly obovate, somewhat undulate, 2.7–3 mm. long, 4 mm. broad; side lobes oblong, obtuse, not saccate at the base; disc with 2 rather obscure, low, parallel keels, otherwise smooth; spur short, clavate, much dilated and globose at the apex, descending, 3–4 mm. long. Column porrect or erect, oblong to clavate, with a very short foot, 3–5.5 mm. long, foot ± 1 mm. long; anther ovate-oblong, papillose at apex, 1.3 mm. long.

Habitat

Forest; 1170–1200 m.
