Gynobase flat, fastigiate , or subulate . Fruit 1-4-seeded drupes or nutlets (mericarps) ; nutlets mostly dry, often ornamented with wings , prickles and/or glochids (stiff bristles with barbed or anchorlike tips ) . Seeds vertical or oblique , coat membranous; embryo straight, less often curved ; cotyledons flat, fleshy .

About 156 genera and 2500 species: temperate and tropical regions , centered in the Mediterranean region; 47 genera and 294 species in China, of which four genera and 156 species are endemic.[1]
