Lianas, the branchlets hexagonal usually with raised angles, without interpetiolar glandular fields, sometimes with foliaceous pseudostipules. Leaves 2-foliolate, frequently with a trifid tendril. Inflorescence a raceme or a racemose panicle, mostly terminal, few- to several-flowered. Calyx cupular, ± truncate, usually with glandular fields below margin; corolla white to dark red-violet or red, tubular-campanulate or narrowly tubular, pubescent outside. Anthers glabrous, the thecae straight, divaricate to subparallel. Ovary oblong, puberulous; ovules few-seriate in each locule; disk annular-pulviniform. Fruit a capsule, the valves convex or biconvex, elliptic-oblong, acutish at extremes, the valves not echinate. Seeds thin, 2-winged, the body brown, usually ± papillose or puberulous.

This species has the branchlet angles rather inconspicuous and is thus ± intermediate between Distictis and Distictella. However, both genera are distinctive in their dark wine-colored flowers.
