Tubers subglobose, 10 x 5 mm. Stem with 2 tubular sheaths at base, upper part with 3 leaves. Leaves cauline, alternate, linear, 15-21 x 0.5-1.0 cm, apex acuminate, base sheathing. Inflorescence 20 cm; peduncle 4-6 cm, ridged, without peduncle-scales; rachis 13-15 cm, with several secund flowers; floral bracts lanceolate, 5-10 x 1-2 mm, 1-veined, exceeding or shorter than the ovary, apex acuminate. Flowers yellowish green, 2-3 mm across, secund, ovary fusiform, slightly arcuate, 5-9 mm long, ridged, apex slightly beaked; dorsal sepal suberect, ovate, 2 x 1 mm, apex sub-obtuse; lateral sepals spreading, ovate, oblique, 2.5 x 1.0 mm, apex sub-obtuse; petals forming a hood with dorsal sepal, oblong, 2.0-4.0 x 1.0 mm, apex obtuse, lip oblong, held horizontally, slightly curved, 1.0-3.0 x 0.5-1.0 mm, base dilated shallowly concave, contracted in the middle, with three ridges running from base to the midlobe, trilobed near apex; lateral lobes falcately triangular, 0.5 x 0.5 mm, apex sub-obtuse; midlobe triangular, 0.7 x 0.4 mm, apex sub-obtuse. Column ca. 1 mm; auricle ca. 0.5 mm, pollinia 0.5 mm, globose; viscidia ovoid, stigma transverse, ca. 1 mm, extending outwards from the rostellum. Flowering time. September. Distribution. Endemic to Nepal. Specimen examined. NEPAL. Chandragiri, 2200 m, 25.09.2012, Raskoti B. B., 571 (KATH). Habitat. Terrestrial on humus-rich grassy slopes at an elevation of 2200 m. Note. This species is close to Herminium lanceum but differs in having smaller flowers and a ridged peduncle; the midlobe of the lip is longer than the lateral lobes, the lateral lobes are triangular and always wider than the midlobe.
