(Greek klytos, splendid or beauteous, and stoma mouth; alluding to the beautiful flowers). Bignoniaceae. Ornamental vines, grown for their beautiful flowers.

Evergreen shrubs, climbing by leaf-tendrils: leaves opposite, with 1 pair of short-stalked entire leaflets, the rachis elongated into a slender simple tendril, sometimes wanting: flowers in 2's, axillary, or terminal or in panicles; calyx campanulate with 5 small or subulate teeth; corolla funnelform-campanulate with imbricate rounded lobes; stamens 4, with spreading anther-cells; disk short; ovary conical, warty, 2-celled, with the ovules in 2 rows: caps. compressed, prickly, sep-ticid, with numerous nearly orbicular winged seeds. - About 8 species in S. Amer., usually described under Bignonia in horticultural writings. Closely related to Bignonia, from which it differs chiefly in its simple slender tendrils, the short disk, the small or subulate calyx-teeth and the prickly pod. Suited for cultivation in subtropical or tropical regions only, or as a stove plant in the N. For cultivation and propogation, see Bignonia.
