These are species with creeping stems and strongly bilabiate (two-lipped) corollas. Columnea nicaraguensis is an example of a species in this section. The corolla is strongly two-lipped and with a galea (hood) formed by the fusion of the two upper petals. The bright red color is also common among the species in this section, but they can also be yellow or occasionally orange or pink.
This Section had been considered one that would likely be upheld as having a single evolutionary origin, but the Jamaican species that have nearly identical corollas seem to have evolved these independently, and likely represent another, as yet undescribed, Section in the genus
Section Columnea contains the majority of species in cultivation, and has been the primary source of hybrids.
