In Habenaria magistrae on the contrary, has more robust plants in general, the inflorescence are rather dense; the labellum is pendulous, oblong and suddenly contracted to an acute apex; the is spur shorter than the ovary; lateral sepals are reflexed; the apex of the petals are rounded and the stigmatic processes are shorter than the blade of the labellum which is attenuate and rounded on both sides."
