Type and only species: Gloxiniopsis racemosa (Benth.) Roalson & Boggan

Distribution: In the Andes of Colombia.

Ecology: Probably as in Gloxinia.

Notes: In habit and flower form G. racemosa is very similar to Gloxinia perennis. However, molecular data suggest that they are not closely related and that G. racemosa merits placement in a distinct genus (Roalson et al. 2005a,b; Boggan 2006)
