Tuber single, 1-2.5 cm long, 0.5-1 cm in diameter, ellipsoid, ovoid. Stem 20-100 cm tall, erect, rather stout, glabrous. Leaves 7-11, 7-29 cm long, 0.5-2(2.5) cm wide, linear or narrowly lanceolate, acute, suberect to spreading, the upper ones much smaller. Inflorescence 5-29 cm long, 6-40-flowered, rather loose. Flowers green with white petals and column. Floral bracts 8-25 mm long, glabrous or pubescent inside. Pedicel and ovary 15-25 mm long, glabrous. Dorsal sepal 5-7.5 mm long, 2-3.5 mm wide, narrowly elliptic or oblong, concave, obtuse or shortly apiculate, sometimes semi-cucullate, glabrous, reflexed. Petals bipartite nearly to the base; anterior lobe 8-16 mm long, 1-1.5 mm wide, obliquely narrowly lanceolate, apiculate, spreading forward, rather thick, glabrous or rarely papillose; posterior lobe 4.5-7.5 mm long, 0.5-1 mm wide, linear, acute, rather thin, papillose and ciliate. Lateral sepals 7-10 mm long, 3.5-6 mm wide, obliquely oblong-obovate or obovate-elliptic, cochleate in the apical half, with short, ca. 0.6 mm long, lateral apiculus, glabrous. Lip tri-partite above an undivided basal part 2-3.5 mm long, minutely papillate, thin at the base, thicker towards the apex; the middle lobe 9-13 mm long, 0.5-1 mm wide, linear, acute or obtuse; side lobes 6-11.5 mm long, 0.5-0.8 mm wide, linear, acute, curved upwards. Spur 8-13 mm long, geniculate, twisted once or twice above, distinctly swollen in the apical third or half, ca. 1.9-2.5 mm in diameter, blunt.

Notes: | This species closely resembles H. schimperiana A. Rich., and it is possible that they form one variable species, in which case H. schimperiana would be the correct name.H. schimperiana is a larger, more robust plant with bigger flowers and a longer pedicel; the anterior petal lobe is ciliate on the margin. |
