Serpaea Gardner, London J. Bot. 7: 296 (1848). Type: Serpaea ovata Gardner = Dimerostemma brasilianum Cass. Note: Robinson (1984) stated that The Gardner genus Serpaea, lectotypified by the same species as Cassinis genus, .... Gardners genus was, at its recognition, monospecific and therefore did not require lectotypification.

Angelphytum G. M. Barroso, Bol. Soc. Argent. Bot. 19(12): 9 (1980). Type: Angelphytum matogrossense G. M. Barroso = Dimerostemma matogrossense (G. M. Barroso) M. D. Moraes

Type: Dimerostemma brasilianum Cass.

Note: Moraes et al. (2007) have submerged Angelphytum into Dimerostemma thus adding one species to the total of Bolivian taxa in Dimerostemma.

Angelphytum herzogii (Hassl.) Pruski, Compositae Newslett. 34: 2 (1999).

Bolivia (Santa Cruz).

Note: This species apparently grows in the same area of Samaipata as Oyedaea neei. Pruski (1999) noted that all material previously named as Zexmenia apensis from Bolivia were in fact Angelphytum herzogii.
