Botanical history

This orchid was described by Robert Allen Rolfe in 1896 . The specific epithet carinata comes from the Latin carinatus , "keeled", and describes the shape of the lip.

The type specimen consists of a few poorly preserved flowers without stems or leaves. Various authors consider Vanilla carinata to be a synonym for other types of vanilla: Hoehne saw it as a synonym for Vanilla planifolia , Govaerts as a synonym for Vanilla gardneri , Soto Arenas and Cribb suspect an identity with Vanilla chamissonis or Vanilla vellozii . Due to the inadequately preserved material, an unequivocal assignment is not possible. The eponymous keels on the lip could also be an artifact that can be traced back to the poor state of preservation.
