Grevillea flexuosa

Grevillea flexuosa, commonly known as zigzag grevillea or tangled grevillea, is an endangered shrub endemic to Western Australia.
Description.
It grows as an irregular shrub up to two metres high, with few branches and no lignotuber. Flowers are cream or yellow and occur in inflorescences typical of "Grevillea".
Taxonomy.
This species was first published as "Anadenia flexuosa" by John Lindley in his 1839 "A Sketch of the Vegetation of the Swan River Colony", based on unspecified material. Lindley referred to it there as "a singular species, allied to "A. pulchella", with most curious zigzag leaves". In 1845, "Anadenia" was demoted to a section of "Grevillea" by Carl Meissner, and this species was thus transferred to "Grevillea" as "Grevillea flexuosa" (Lindl.) Meisn.. It has since had a fairly uncomplicated taxonomic history, the only incident being the publication by George Bentham in 1870 of a variety, "G. flexuosa" var. "pauciloba", which was subsequently found to be a taxonomic synonym of "G. synapheae".
Distribution and habitat.
It occurs only within a small area east of Perth, in the Jarrah Forest biogeographic region. The soil of area is red-brown sand over laterite or granite.
Ecology.
It has been gazetted as "rare" under Western Australia's Wildlife Conservation Act 1950, and "vulnerable" under the federal Environment Protection and Biodiversity Conservation Act 1999.
