Family Proteaceae

Trees or shrubs . Stipules absent. Leaves alternate, rarely opposite or whorled , simple or variously divided . Inflorescences axillary , ramiflorous , cauliflorous , or terminal , simple or rarely compound , with flowers borne laterally either in pairs or sometimes singly, racemose, sometimes spicate , paniculate , or condensed into a head ; bracts subtending flower pairs usually small, sometimes accrescent and woody; floral bracts usually minute or absent. Flowers bisexual or rarely unisexual and dioecious, actinomorphic or zygomorphic. Perianth segments (3 or) 4(or 5), valvate , usually tubular in bud; limb short, variously split at anthesis . Stamens 4, opposite perianth segments; filaments usually adnate to perianth and not distinct ; anthers basifixed , usually 2-loculed, longitudinally dehiscent , connective often prolonged. Hypogynous glands 4 (or 1-3 or absent), free or variously connate . Ovary superior, 1-loculed, sessile or stipitate ; ovules 1 or 2(or more), pendulous, laterally or basally, rarely subapically attached. Style terminal, simple, often apically clavate ; stigma terminal or lateral , mostly small. Fruit a follicle, achene, or drupe or drupaceous . Seeds 1 or 2(or few to many), sometimes winged ; endosperm absent (or vestigial ) ; embryo usually straight; cotyledons thin or thick and fleshy ; radicle short, inferior.

About 80 genera and ca. 1700 species: mostly in tropics and subtropics, especially in S Africa and Australia: three genera (one introduced ) and 25 species (12 endemic, two introduced) in China.

The family is subdivided into Bellendenoideae, Caranarvonioideae, Eidotheoideae, Grevilleoideae, Persoonioideae, Proteoideae, and Sphalmioideae; all Chinese genera belong to Grevilleoideae. Grevillea robusta is grown extensively as a street tree in S China, especially in Yunnan.Huaxing Qiu & Peter H. Weston "Proteaceae". in Flora of China Vol. 5 Page 192.
