Sepals 5, short, sometimes minute; corolla slit to base on upper side, lobes subequal, spreading like a fan or the fingers of an open hand; wings equal; auricles absent; stamens free; ovary inferior, two-celled with one erect ovule in each cell, rarely one-celled with one or two erect basal ovules; style usually curved inwards at summit; indusium cup-shaped, ciliate at summit; fruit indehiscent, dry or succulent, endocarp usually bony; seeds oblong, embryo mostly terete.
