Common Name The Tremulous Bulbophyllum

Flower Size 1" [2.5 cm]

Found as a unifoliate, hot to cool growing epiphyte in India at elevations around 1000 meters with small pseudobulbs and a single, apical, ovate leaf where it blooms on a basal, 8" [20 cm] long, often more than one, few to several [6 to 10] flowered inflorescence that holds the pubescent flowers above the leaves. This species requires ample moisture, partial shade and good air circulation.

This species and B saltatorium are quite similar, but the main differentiation is the elliptic-ovate, ciliate petals of this species versus the linear, glabrous petals of B saltatorium
