Tall trees. Leaves bunched at ends of branches, +/- obovate, obscurely irregularly crenate, glabrous underneath, often with large hairy pits in axils of lateral nerves; petiole short, puberulous when young. Flowers several in short terminal panicles. Calyx: lobes 4, rounded and shortly ciliate. Petals 4, hooded, glabrous. Stamens fused at base; filaments filiform; anthers 2-thecous, appearing 4-lobed due to divergent thecae, basifixed. Ovary 2-locular, 4-ridged to 4-winged; ovules many in 2 rows in each locule; style filiform. Fruit broadly 4-winged (as in Combretum), almost orbicular, emarginate. Seeds 1(-4), fusiform.
