Grevillea wittweri is a shrub of the genus Grevillea native to an area in the southern Wheatbelt region of Western Australia.^[2] It was listed as a vulnerable species in 2018 by the International Union for Conservation of Nature.^[1]

Description[]

The dense multi-branched spreading shrub typically grows to a height of 1 to 2.2 metres (3.3 to 7.2 ft) and has non-glaucous branchlets. It has simple undissected subpinnatisect to bipinnatisect leaves with a blade that is 40 to 80 millimetres (1.57 to 3.15 in) in length. It blooms between September and April and produces a terminal raceme irregular inflorescence with green, pink or brown flowers with red or purple styles. Later it forms oblong or ovoid glandular hairy fruit that are 12 to 14 mm (0.5 to 0.6 in) long.^[2] It regenerates from seed and has a generation length of about 25 years.^[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). The name is commonly misapplied to Grevillea armigera.^[3]

Distribution[]

It has a scattered distribution throughout the Wheatbelt from between the Shire of Kent, Shire of Kondinin, Shire of Ravensthorpe, Shire of Kulin and Shire of Lake Grace. It is commonly found growing on sandplains in sandy soils often around salt lakes^[2] as a part of shrubland and mallee shrubland communties. The population is declining and spread over an area of 14,520 km² (5,610 sq mi).^[1]
