Cadetia cuneilabia is only known from the original description, the type material being lost. Judging from this description it is quite similar to and possibly conspecific with Cadetia chionantha, but C. cuneilabia apparently has a longer mentum. Schlechter himself compared it to Cadetia chamaephytum, which however is much less similar.
