Bulbophyllum echinolabium

This medium-sized, warm to cool growing epiphyte is found in Sulawesi and Borneo at elevations of 600 to 1200 meters. It has ovoid, non-angular pseudobulbs spaced 1.8 to 3.5 cm apart, each carrying a single, elliptic to obovate leaf with a long petiolate base. Blooming in spring and summer, it produces a basal, 70 cm long, successively single-flowered inflorescence that slowly extends, bearing up to 10 unpleasant-smelling flowers.
