Common Name Weddel's Bulbophyllum [English Plant Collector Brazil 1800's]
Flower Size 1" [2.5 cm]
Found in Espirito Santo, Rio de Janiero and Minas Gerais states of Brazil and in Bolivia at elevations around 1000 to 1500 meters, as a miniature sized, cool to warm growing, unifoliate epiphyte with egg-shaped, 4 angled pseudobulbs carrying a single, apical, rigidly fleshy, oblong, obtuse leaf that blooms in the summer and fall on a basal, slender, 12" [30 cm] long, erect many flowered inflorescence that holds the 6" [15 cm] long, pendant rachis with the densely many, successively opening flowers held above the leaves.
B weddelii has an oblong-linear lip and is unique in the Colombian unifoliate species as all others have an ovate to obovate lip in outline
I have found this orchid in Minas Gerais growing on bare rocks in full sun [See photo by Jay Pfahl above] as well as on mossy rocks in heavy shade.
