Flowers solitary, axillary, pendent, with long, erect pedicels; white to pink or mauve, sometimes violet or yellow. Calyx much shorter than corolla tube, somewhat oblique, pubescent; segments linear-lanceolate to ovate-lanceolate. Corolla pilose; tube constricted near base and somewhat saccate on posterior side, then obliquely campanulate, curved; limb sub-bilabiate, upper and lateral lobes subequal, obovate, anterior one larger, with dark stripes or lines of dots running into the tube. Stamens subdidynamous, shorter pair included, longer ones just exserted; filaments linear; anthers with thecae parallel; staminodes 0. Nectary annular. Ovary 2-locular, false septum 0, usually with 2 or 5 ovules per locule; style somewhat compressed, linear, included; stigma of 2 ovate lobes. Fruit indehiscent, woody, longitudinally compressed to discoid, central part slightly to strongly raised, with 2 erect, conical spines on upper face and a hard, narrow wing. Seeds obovate to oblanceolate, compressed, with a groove on edges; testa somewhat crustaceous, almost smooth, usually dark-coloured.
