Brachymenium consimile and B. radiculosum differ from other members of this genus in Bolivia by the obovate leaves and generally occurring on shrubs or on twigs or branches of treelets and trees. The former species is distinguished from the latter by the broadly obovate leaves, and reduced endostomal segments and cilia, the latter species by the narrowly obovate leaves and well developed endostomal segments and absence of cilia.
