Stems woody. Leaves 5-pli-nerved. Inflorescence racemose, terminal or axillary. Flowers 5-merous. Hypanthium and calyx densely hirsute, the calyx calyptriform, deciduous at anthesis, entire or separable into five sepals. Petals ample. Torus expanded horizontally even before anthesis, thick and fleshy, bearing the stamens and petals on its distal face, more or less arched over the mouth of the hypanthium. Stamens 5, episepalous in position, the stout filaments strongly incurved at the summit and again recurved to the erect anther; anthers oblong, stout, 2-celled, opening by a lateral pore at the summit of the deep ventral furrow; connective neither prolonged nor appendaged, continued without obvious articulation into the filament. Ovary wholly inferior, 5-celled; ovules numerous, minute, on an elongate placenta which is attached to the axial angle of the loculus by its center only. Style clavate, stout, the summit sharply curved or recurved to the broad truncate stigma. Fruit a capsule, dehiscent by 5 valves. Seeds numerous, straight, the raphe surrounded by a broad fimbriate wing.
