Umbrella Bulb-Leaf Orchid lives on mossy branches in old, dwarf, gnarled trees, as a miniature sized orchid. Pseudobulbs are enveloped basally by a fibrous sheath and carry a single, leathery, narrowly elliptic, stalked leaf. The plant blooms on a slender, 20 cm long, basal, 5-8 flowered inflorescence that is just shorter than the leaf and has an umbel of foul smelling flowers. Flowers are dark greenish yellow or dark brown with purplish tip except whitish lip. Dorsal sepal is ovate, concave, about 9 x 5 mm, tip pointed; lateral sepals curved-lanceshaped, about 15 x 5 mm, base adnate to column foot, twisted near base, their lower edges of basal part fused, tip blunt. Petals are ovate, about 7 x 5 mm, entire, blunt-rounded. Lip is recurved, strap-shaped, about 5 mm, fleshy, base almost heart-shaped, tip blunt. Umbrella Bulb-Leaf Orchid is found in the Himalayas to Taiwan and Indo-China, and also in the Western Ghats.
