Bulbophyllum roxburghii - Sikkim Bulb-Leaf Orchid

Sikkim Bulb-Leaf Orchid is a medium sized orchid growing on trees, with 1.5-3 cm between each nearly spherical pseudobulb. Flowers are of pale brownish green base with reddish brown to dark purple spots and veins. The dorsal sepal is greenish brown with five dark purple veins and a few spots of the same color, the lateral sepals are greenish brown with numerous spots and markings of various shades of reddish brown. Petals are rather with darker shade than the sepals and with three dark purple veins and numerous spots. The lip is of brownish yellow base and with purple spots and fine margin of the same shade. Both the dorsal sepal and petals are with purple colored marginal cilia. The dorsal sepals are small, free from the lateral pair at its base, concave. The lateral pair, much longer than the dorsal, 3 to 4 times, narrowly oblong, very blunt, somewhat sickle shaped, coherent. Petals are ovate, somewhat pointed, with very oblique bases, the edges fringed with hairs. Lip is broadly ovate at the base much narrowed in the anterior half, the tip blunt, the edges entire. The bulbs are enveloped basally by fibrous sheaths and carrying a single, apical, leathery, linear-oblong, blunt, obliquely notched, stalkless to shortly stalked leaf. The plant blooms in the spring through summer on an erect, basal, up to 20 cm long, slender, bracteate, 5-12 flowered inflorescence that exceeds the height of the leaves and has an apical umbel of flowers. Sikkim Bulb-Leaf Orchid is found in Nepal to Sikkim, Bhutan and NE India.
