Notes

The collection Schomburgk s.n. (NY, F photo of B type negative nr 13342) belongs to this species, but was erroneously labeled as Hippocratea micrantha Cambess. It also bears the wrong determination Elachyptera micrantha (Cambess.) A.C. Smith written in pencil, this collection is not a type specimen.
The specimen described by Aublet under the name Tontelea scandens proved to belong to Elachyptera floribunda.
