Shrubs [trees], hairy or glabrate, not viscid. Stems erect [or procumbent]. Leaves: stipules persistent, subulate or linear to falcate; blade ovate, unlobed, shallowly lobed, or deeply parted, base subcordate or cordate, margins entire, surfaces glabrous or stellate-hairy, often with abaxial foliar nectaries. Inflorescences axillary, solitary flowers or flowers sympodially arranged; involucellar bractlets deciduous or persistent, 3, distinct. Flowers: calyx not accrescent, not inflated, lobes sometimes unribbed, ovate or triangular, glabrous or hairy; corolla cream or yellow [rose], sometimes fading rose, with or without dark spot at center; staminal column included; ovary 3–5-carpellate; style unbranched; stigmas decurrent-clavate. Fruits capsules, erect, not inflated, ovoid or subglobose to oblong, leathery, usually glabrous. Seeds [2–]24, densely comose to glabrate or glabrous. x = 13.
Distribution
