Type: Schlechter 17062 (syn B, lost); 18978 (syn B, lost)
Epiphytic, erect or spreading, several-stemmed. Rhizome very short; roots filiform, elongated, flexuose, glabrous. Stems straight, entirely hidden by the leaf-bases, densely 6-9-leaved. Leaves suberect, free part linear-lanceolate or linear-ligulate, acute, falcate, 9-17 cm long, at the base 0.4-0.7 cm wide. Inflorescence densely many-flowered, cylindrical, almost as long as the upper leaves, 0.6 cm diam. across the flowers. Floral bracts patent, lanceolate or oblong-lanceolate, acuminate, dorsally keeled, margins irregularly subdentate, glabrous, as long as the flowers or a little longer. Flowers patent, at the apex slightly incurved, very small, glabrous. Median sepal oblong, obtuse, almost 02 cm long. Lateral sepals falcate-ovate, obtuse. Petals obliquely oblong-ligulate, obtuse, margins minutely serrulate, somewhat dilated in the middle, almost as long as the sepals. Lip very small, almost 0.15 cm long, at the base reniform-subcordate, above the middle strongly narrowed and elongated into an oblong, obtuse lobe. Column short, thickened towards the apex. Ovary clavate, glabrous, including the pedicel 0.25 cm long. (After Schlechter, 1911-1914)
