Half-hardy climbing herbaceous perennials, usually treated as annuals for open-air culture. Leaves hairy, simple, cordate or triangular, coarsely toothed, petiolate. Flowers large, showy, solitary, axillary. Calyx ample, 5-lobed, herbaceous. Corolla tubular-campanulate; limb of 5 spreading lobes. Capsule 2-celled, each cell opening by an irregular pore below the apex. Seeds fringed, whence the name, from a crest, and a seed. There are two or three Mexican species.
