Family Proteaceae
Trees

. 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.[1]
Habitat
Ecology: It grows on rocky soils derived from sandstone in mountain fynbos.[2]
