Grevillea linearifolia
Grevillea linearifolia, commonly known as linear-leaf grevillea, is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is an open, erect shrub with linear to narrowly elliptic leaves, and clusters of white flowers.
Description
Grevillea linearifolia is an erect, open shrub that typically grows to a height of and has ridged, silky-hairy branchlets. Its leaves are linear to narrowly elliptic, mostly long and wide, sometimes arranged singly, or in clusters of three. The flowers are arranged, usually in large groups held above the leaves, on the ends of branches on a peduncle long. The flowers are white, silky-hairy on the outside, sometimes with a faint pink tinge, and the pistil is long with a hooked style. Flowering mainly occurs from August to December, but also sporadically in other months and the fruit is a narrowly oval follicle long.Taxonomy
This species was first formally described in 1798 by Cavanilles, who gave it the name Embothrium linearifolium in his Icones et Descriptiones Plantarum from specimens collected near Port Jackson. In George Druce changed the name to Grevillea linearifolia in the supplement to The Botanical Exchange Club and Society of the British Isles Report for 1916. The specific epithet means "linear-leaved".The taxonomic limits of G. linearifolia are difficult to establish. In addition to variations between populations, the species is said to form "an intergrading complex" with G. parviflora, and may intergrade with G. patulifolia and/or G. humilis subsp. humilis. It is also known to hybridise often with G. sericea, and occasional hybrids with G. diffusa subsp. filipendula have also been reported.
