Species of shrub in the family Proteaceae endemic to Western Australia
Grevillea uncinulata, also known as hook-leaf grevillea, is a shrub of the genus Grevillea native to an area in the Wheatbelt, southern Mid West, northern Great Southern and western Goldfields-Esperance regions of Western Australia.

Description

The erect open shrub typically grows to a height of 0.3 to 1 metre (1.0 to 3.3 ft) and has non-glaucous branchlets. It has simple undissected flat linear leaves with a blade that is 5 to 20 millimetres (0.20 to 0.79 in) in length and 1 mm (0.04 in) wide. It blooms between May and September and produces an axillary or terminal raceme irregular inflorescence with white or cream flowers with white or cream styles. Later it forms ridged or ribbed oblong or ellipsoidal hairy fruit that are 8 to 13 mm (0.3 to 0.5 in) long.

Taxonomy

The species was first formally described by the botanist Ludwig Diels in 1904 as a part of the work Fragmenta Phytographiae Australiae occidentalis. Beitrage zur Kenntnis der Pflanzen Westaustraliens, ihrer Verbreitung und ihrer Lebensverhaltnisse as published in 'Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie written by Diels and Ernst Georg Pritzel. Two synonyms are: Grevillea uncinulata Diels subsp. uncinulata and Grevillea oxystigma var. villosa Benth.

Distribution

The shrub is quite widespread through parts of the Wheatbelt extending from around Carnamah in the north-west down to Cranbrook in the south west out to around Ravensthorpe in the east. It is usually found growing as a part of shrubland communities in sandy to gravelly lateritic soils.
