Description Herbs, undershrubs or shrubs, the indumentum usually of stellate hairs. Leaves petiolate, the stipules caducous, the blade cordate or truncate at the base, the mar- gins entire or dentate. Flowers axillary and solitary, or in terminal, paniculiform inflorescences; epicalyx wanting; calyx 5-merous, campanulate or somewhat turbi- nate, lobed to about or to below the middle, persistent; corolla small or medium- sized, the petals 5, the base adnate to the staminal tube; staminal tube short, ventricose, filamentiferous at the apex, the filaments relatively numerous, the anthers reniform; ovary of 5, rarely 3-4 or 6 carpels, each carpel (1)3-ovulate, the ovules anatropous, pendulous; styles isomerous with the carpels, the stigmas capi- tate. Fruits more or less stellate-turbinate or globose, of 5, rarely 3-4 or 6 mericarps, these angulate to rostrate apically and with the beaks pointing outwards, more or less completely divided into 2 superposed cavities by tranversal or oblique constric- tion of the lateral walls, the lower cavity 1-seeded, the upper with 2 collateral seeds, ultimately incompletely 2-valvate; seeds subglobose-reniform, pubescent; embryo curved, the albumen scant; cotyledons plicate.
