Bulbophyllum atrolabium Schltr., Bot. Jahrb. Syst. 58 (1923) 144

Type: Ledermann 8181 (holo B, lost)

Epiphyte, erect or sprawling, c. 30 cm long. Rhizome flexuose, hardly 2 mm diam. Pseudobulbs entirely connate to the rhizome, superposed, cylindrical, 1.5-2 cm long; 1-leaved. Leaves linear-ligulate, apiculate, subcoriaceous, glabrous, 5-6.5 by 0.6-0.75 cm; base gradually somewhat narrowed; margins slightly recurved. Inflorescences 1-flowered, from the base of the pseudobulbs, very short. Floral bracts ovate, apiculate, much shorter than the pedicellate ovary. Flowers thin-textured. Sepals lanceolate, elongate-strongly acuminate, glabrous, 1.1 cm long. Lateral sepals at the base along the front margin dilated, forming a short, obtuse mentum with the column-foot. Petals much smaller than the sepals, obliquely rhombic-ovate, subobtuse, glabrous, 0.15 cm long; base narrowed. Lip lanceolate, acute, 0.28 cm long; basal third somewhat narrowed; margins and upper side along the margins shortly papillose-puberulous. Column short, glabrous, 0.15 cm long; stelidia erect, falcate-subulate, hardly longer than the anther. Ovary pedicellate, subclavate, glabrous, 0.5 cm long. (After Schlechter, 1923)
