Type. Without locality, Venezuela, 1842-43, Funcke 793 (K).

Study of the photo of the type of Deppea (?) venezuelensis Standi, from G, together with the original description, leaves no doubt that it and Pittierothamnus elineolatus are conspecific. In describing his plant, Standley remarked, “I feel confident that this plant does not belong to the genus Deppea .... It has been impossible to discover a more satisfactory place for it, but it is probable that the flowers, when available, will show that the plant represents a new generic type.” Again, when he described Deppea (?) colombiana, he stated that “The generic position of both these plants [Deppea (?) venezuelensis and Deppea (?) colombiana] is annoyingly uncertain, but probably both belong to a distinct genus that must receive a name when flowering material of one or the other has become accessible.” A photograph in the Paris Herbarium of Funck 793 labelled with the unpublished manuscript name, “Rondeletia funckiana Baill.,” is to be identified with Amphidasya venezuelensis.

Standley did not believe that the fruit was fleshy, and, for that reason, did not assign it in the tribe Mussaendeae where it appears now to belong, along with Sabicea. Standley separated Deppea colombiana from D. venezuelensis by the laciniate instead of entire stipules. As has already been indicated in other species discussed above, the character of prominent long-lacinate stipules breaks down in such species as A. bullata, A. neblinae, and A. intermedia, all of which show reduced stipules with relatively shorter and fewer segments or bristles.
