Leaves alternate; stipules small, sheathing bud, fugacious; petiole swollen at base and apex; leaf blade simple, palmately veined. Inflorescence a terminal panicle. Flowers bisexual, actinomorphic. Sepals 5, free, imbricate, with basal, abaxial glands, fugacious. Petals 5, imbricate, large and conspicuous. Stamens many, free or slightly united at base; anthers oblong, with 2 inverted, U-shaped thecae, dehiscing by short, apical slits on bend. Ovary superior, 1-loculed; ovules many on 2 parietal placentas; style slender; stigmas 2-lobed. Fruit a capsule, loculicidally 2-valved, usually spiny.
