Although this taxon is rather uniform in general aspect, some variation may be noted. In Schultes & Cabrera 19119 from Vaupes, Colombia, the corollas are the largest recorded, with the total corolla length 46 mm, the tube 27 mm long, and the lobes 3 mm wide. In the Venezuelan collections the recorded lengths of the corolla vary from 27-43 mm, 15-22 mm for the tube, and 2-2.5 mm wide for the lobes. In Schultes & Cabrera 18323, also from Vaupés, Colombia, the leaves are much reduced, and are only 5-7 cm long on the NY and G sheets with petioles only 5-9 mm long with leaf bases obtuse to subobtuse, whereas in the other collections examined the leaves are mainly 8-17 cm long with petioles 12-20 mm long, and the leaf bases are usually acute to subacute.
