Flowers bisexual, solitary or in axillary cymes, racemes or panicles, usually yellow or white; sepals and petals similar, 4-6, free, imbricate or the former rarely valvate, petals sometimes reduced to nectaries, hypogynous, caducous; stamens as many as the petals and opposite to them, free or connate, hypogynous, filaments short, anthers usually dehiscing by 2 valves hinged at top; ovary superior, 1-celled, style short or absent, stigma dilated or conic or oblong; ovules few to many, rarely 1, on the ventral suture or at base of ovary, anatropous, rarely orthotropous. Fruit a berry or pod; seeds with a crustaceous fleshy or bony testa; endosperm copious, dense; embryo usually small, straight or curved.
