The Guianan plants of this species have traditionally been placed in Columnea aureonitens Hook. The characters distinguishing that species from C. sanguinea were the color and investiture of the lower leaf surface. The plants of the two taxa display all the characteristics and intermediates that cannot be distinguished reliably. The typical form of this species has prominent red areas near the apices on the lower leaf surfaces as seen in populations from Hispaniola, Trinidad and elsewhere. The all-green form of the species is found in Cuba, C America to Ecuador and Bolivia, and the Guianas.
