Grevillea tenuiflora, also commonly known as amber grevillea,[1] is a shrub of the genus Grevillea native to an area in the Wheatbelt and Mid West regions of Western Australia.[2]
The low spreading shrub typically grows to a height of 0.5 to 1 metre (1.6 to 3.3 ft) and has non-glaucous branchlets. It has simple, dissected and subpinnatisect leaves with a blade that is 15 to 50 millimetres (0.59 to 1.97 in). It blooms between August and October and produces a terminal raceme irregular inflorescence with orange flowers and orange styles. Later it forms ovoid, glandular hairy, red-brown fruit that are 11 to 14 mm (0.4 to 0.6 in) long.[2]
The specific epithet is derived from the Latin word tenuis, meaning narrow and the word lobus meaning lobe in reference to the shape of the leaf lobes.[3] The species was first described by the botanist Charles Austin Gardner in 1934 as a part of the work Contributiones Florae Australiae Occidentalis No. VIII as published in the Journal of the Royal Society of Western Australia.[1]
The species has a native range extending from inland of Geraldton extending south east through Morawa, Western Australia, Dalwallinu, Western Australia to around Ballidu, Western Australia. It is found growing in sand clay to loamy soils often around granite outcrops.[2]
