Plants in the genus Grevillea are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus Grevillea are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season. Taxonomy The genus Grevillea was first formally described in 1809 by Joseph Knight from an unpublished manuscript by Robert Brown. Knight gave the spelling Grevillia, corrected by Brown in 1810 to Grevillea in Transactions of the Linnean Society of London. The genus was named in honour of Charles Francis Greville, an 18th-century patron of botany and co-founder of the Royal Horticultural Society. Species There are over 350 species which are endemic to Australia. Five other species are endemic to areas outside Australia. Three of these (G. exul, G. gillivrayi, and G. meisneri) are endemic to New Caledonia, while G. elbertii and G. papuana are endemic to Sulawesi and New Guinea respectively. Two other
