Correction of the Malaxis name by Andre Schuiteman of Kew, not Malaxis purpurea but most likely a purple form of Malaxis/Crepidium bancanoides based on the presence of "teeth" on the lip. The genus name depends on which taxonomist you talk to as Crepidium used to be a section within Malaxis but has been raised to a genus status in 1995 by a guy named Szlachetko. Some taxonomists accept the reinstatement of Crepidium Blume as a genus, others don't......
Edit: The reinstatement of Crepidium seems to be based on DNA which means that most SE Asian Malaxis are now Crepidium.
