Characteristics

Trailing or climbing shrubs. Branches lenticellate; branchlets glabrous or sparsely pubescent. Leaves opposite; glabrous or pubescent on midrib and veins; long slender glands in the axils. Inflorescence an axillary cyme, all axes pubescent; flowers 5-merous. Sepals ovate to linear; pubescent; with or without colleters inside. Corolla lobes dextrorse; mature corolla infundibuliform; tube widening around the middle; lobes spreading. Stamens exserted; inserted on the corolla tube at the point where the tube widens, adnate to the style head; filaments short, pilose, having a large bulbous swelling at the apex; anthers fertile in the upper half only, the lower half sterile, laterally with lignified guide rails and slightly curved sagittate appendages at the base. Disk 5-lobed; surrounding ovary to about the same length. Gynoecium 2-carpellate, apocarpous but apically united into a common style, pubescent; ovules numerous; style pubescent. Fruit a follicle, sometimes formed from only one of the carpels; not lenticellate. Seeds ellipsoid, flattened; pubescent; with an apical coma.
