Abstract


Thismia okhaensis is described and illustrated as a new species discovered in Ô Kha Valley, Khánh Hòa Province in central Vietnam. The new species belongs to section Sarcosiphon on account of having mitre-like flowers. It is allied to T. angustimitra and T. mirabilis, but it differs in having a convex top mitre with three digitate furrows, involucral bracts with round apex, apertures totally hidden under the mitre, and connective appendages with lateral teeth.
