Notes: Cadetia sayeri is one of several species of Cadetia that currently are only known from the original description. In the present case, this description strongly suggests Cadetia chionantha, a common mountain species, except that the apex of the lip is emarginate in C. chionantha, while it is described as truncate in C. sayeri.

Cultivation: Cool growing epiphyte.
