Flowers regular, hermaphrodite or unisexual. Perianth simple, 
sometimes fleshy; tube adnate to the ovary and often produced above 
it, solid in the male flowers ; lobes 3-10, imbricate or valvate, 1-2-seriate. 
Stamens 8 to many, free or united; anthers surrounding a central 
column and dehiscing by apical slits, or forming a lobed ring inside the 
perianth-tube with long sinuous cells like those of some Cucurbitacee, 
dehiscing longitudinally but folded so that the slits are near together 
and across the ring. Ovary inferior, 1-celled; placentas parietal or 
numerous and pendulous from the top of the cell, entirely covered with 
ovules ; stigma sessile, flat or cushion-like, lobed. Fruit a berry, globose 
or turbinate. Seeds minute, albuminous; embryo small.—Fleshy root 
or branch parasites, leafless or with the leaves reduced to scales.
