Notes:
This species is likely conspecific with V. phalaenopsis Rchb. f. ex Van Houtte from the Seychelles and possibly V. roscheri from Zanzibar and elsewhere in eastern Africa. Provisionally, we retain the Malagasy species as distinct (following current usage, as established by Rolfe, 1896), until the synonymy can be confirmed through further study, but note that V. phalaenopsis has nomenclatural priority over the other names if they are synonymised.
