Description Lianas, shrubs or trees, often copiously pubescent or scabrous. Leaves alternate, petiolate, simple, frequently coriaceous, penninerved, estipulate. Inflorescences thyrsiform, paniculiform or obscurely glomerulate. Flowers hypogynous, perfect or unisexual, actinomorphic, the sepals 3-7, frequently 5, the petals 2-6, yellow, white or rarely pinkish, usually emarginate or incised, often somewhat crumpled in the bud, caducous (except in Saurauia), the stamens indefinite, free or fused at the base (adnate to the corolla in Saurauia), the anthers basifixed and longitudinally dehiscent, or bifurcate, versatile and basally dehiscent by rimiform pores, the carpels 1-5, free to fused, the ovules 1 to several, anatropous, basal, and erect (numerous and axile in Saurauia), the styles free, as many as the carpels, the stigmas apical, simple to capitate or peltate. Fruits follicular to baccate, the seeds 1-co, arillate (nonarillate in Saurauia), embedded in copious mealy or fleshy en- dosperm.
