Inflorescences compound racemes, axillary on terminal node, 1 per node; bracts early caducous, pubescent outside, glabrous inside. Flowers sometimes unisexual by reduction. Sepals 1 or absent, only abaxial sepal sometimes present and then fused to the bracteoles. Petals usually absent, rarely a vestigial lateral petal present. Stamens 6-8, all shortly fused at base; anthers relatively large, purple-pink, without dorsal teeth, dorsifixed. Ovary shortly stalked, velvety; ovules 1-3; style insertion excentric, style usually geniculate at base and near apex; stigma +/- mushroom-shaped. Pod laterally flattened, distinctly beaked, puberulous to velvety; lateral nerve running above middle of pod; wings of upper suture narrow. Seeds with a very thin membranous testa.
