:—Despite many-years, special field searches of professional botanists and numerous orchid enthusiasts only few samples of this extremely rare species were found in one location. Being into consideration vast deforestation in Ngoc Linh Mountains it may be expected that this species stands on the verge of full extinction in the nature.
