Column short, pubescent in front, stelidia bidentate, filament tooth-like, acute.
(after Schlechter 1912 - as Cadetia potamophila).
Flower white, midlobe of lip yellowish, apex of column red.

Cadetia albiflora is a small-flowered relative of Cadetia umbellata. Ridley's original description is poor and inaccurate, therefore we have here translated Schlechter's description of the synonymous Cadetia potamophila. The leaves can be wider than those Schlechter described, to c. 6 mm wide in the type of his var. kenejiae.
