FOund in 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 on a basal, slender, 12" [30 cm] long, erect many flowered inflorescence that holds 6" [15 cm] long, pendant rachis with the densely many, successively opening flowers held above the leaves and occurs in the summer and fall. I have found this orchid in Minas Gerais growing on bare rocks in full sun [See photo]as well as on mossy rocks in heavy shade.
