Description

The spiny irregularly branched shrub typically grows to a height of 1 to 1.5 metres (3.3 to 4.9 ft) and has non-glaucous branchlets. It has simple, dissected, tripartite leaves with a blade that is 7 to 20 millimetres (0.28 to 0.79 in). It blooms from June to September and produces an axillary or terminal raceme regular inflorescence with white or cream flowers and white styles. Later it forms rugose oblong to ellipsoidal glabrous fruit that are 7 to 8 mm (0.3 to 0.3 in) long.[1]

Taxonomy

The species was first formally described by the botanist Donald McGillivray in 1986 as a part of the work New Names in Grevillea (Proteaceae).[2]

Distribution

The shrub is found in the Wheat belt region to the north and east of Perth. The range is from west of Three Springs in the north west down to around the Wandoo National Park in the south west and out to around Tammin in the east. It is often found growing in sandy to sandy loamy or clay soils often with lateritic gravel.[1]
