This genus is characterized by magenta to white "Cydista-type"' flowers lacking a nectariferous disc and with a cylindric lepidote ovary. The compressed fruits are linear to oblong. The branchlets are commonly tetragonal, interpedolar glandular fields are absent, and the tendrils are simple. It occurs from southern Mexico and the West Indies south through most of Amazonia. A single species reaches upland Guayana (see also C. lilacina. Part II).
