Found in Sierra Leone, Ivory Coast, Ghana, Togo, Liberia, Nigeria, Gabon, Gulf of Guinea Islands, Cameroon, Central African Republic, Zaire, Uganda, Kenya, Ethiopia, Tanzania, Mozambique, Malawi, Zambia, Zimbabwe and Angola as a miniature sized, hot to warm growing, bifoliate epiphyte and an occasional lithophyte in open woodlands and riverine forests at elevations of 600 to 2100 meters with oblong to ovoid pseudobulbs carrying to 3, apical, oblong, apex rounded and emarginate thick and leathery leaf that blooms in the fall on a single, basal, erect, 20" [50 cm] and more long inflorescence arising on a mature pseudobulb with many [50], small, successive opening flowers spread out along the leaflike, flattened rachis with dentate edges.
This plant needs a distinct dry period in the winter as you do need some pseudobulb shriveling for strong growth to come on in the spring.
