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.[1]
