Description

The shrub typically grows to a height of 0.5 to 3 metres (1.6 to 9.8 ft) and has non-glaucous branchlets. It has simple, flat, obovate and undissected leaves with a blade that is 8 to 55 millimetres (0.31 to 2.17 in) long and 5 to 27 mm (0.20 to 1.06 in) wide. It blooms from July to September and produces an axillary or terminal raceme regular inflorescence with yellow flowers and yellow styles. Later it forms smooth or rugose obovoid glabrous fruit that is 7 to 17 mm (0.3 to 0.7 in) long.[1]

It is similar to Grevillea integrifolia but has ridged branchlets.[2]

Taxonomy

The species was first formally described by the botanist Carl Meissner in 1848 as a part of Proteaceae as published in Johann Georg Christian Lehmann's work Plantae Preissianae. The only synonym is Grevillea integrifolia subsp. shuttleworthiana.[3] There are three recognised subspecies:

• Grevillea shuttleworthiana subsp. canarina
• Grevillea shuttleworthiana subsp. obovata
• Grevillea shuttleworthiana subsp. shuttleworthiana

Distribution

Grevillea shuttleworthiana is found from Kalbarri in the north and as far south as Ravensthorpe. It extends west from the sandplains of Perth as far east as Mount Jackson near Southern Cross.[2] It grows in shrubland or heathland amongst medium to low trees in gravelly, sandy or clay soils.[1]
