Grevillea tenuiloba

Grevillea tenuiflora is a low, spreading shrub that typically grows to a height of 40–100 cm (16–39 in) and up to 3 m (9.8 ft) wide. Its leaves are pinnatipartite, 15–50 mm (0.59–1.97 in) long usually with 5 to 11 linear to more or less cylindrical lobes 2–25 mm (0.079–0.984 in) long, 0.6–1.3 mm (0.024–0.051 in) wide and sharply pointed. The leaf rachis is strongly turned down, and the edges of the leaves are rolled under, enclosing most of the lower surface. The flowers are pale to rich orange, often borne on or close to the ground, on one side of floral rachis 55–135 mm (2.2–5.3 in) long, the pistil 23–34 mm (0.91–1.34 in) long. Flowering occurs from August to October, and the fruit is a woolly-hairy follicle 11–14 mm (0.43–0.55 in) long.[2][3]

Grevillea tenuiflora was first formally described in 1933 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens collected in 1932 near Dandaragan by William Blackall.[4][5] The specific epithet (tenuiloba) is derived from the Latin word tenuis, meaning narrow and the word lobus meaning lobe in reference to the shape of the leaf lobes.[6]

Amber grevillea grows in Melaleuca shrubland between Wongan Hills and Jibberding near Wubin in the Avon Wheatbelt bioregion of south-western Western Australia.[3][2]

Grevillea tenuiloba is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]

This grevillea can be grown from scarified seed or from firm cuttings of the current season's growth. It is best suited to a dry summer climate, unless grafted on to a hardy rootstock.[6]
