About 80 genera and ca.

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]
