Grevillea plurijuga is a species of flowering plant in the family Proteaceae and is endemic to southern Western Australia. It is a prostrate to low-lying or dense mounded to erect shrub with divided leaves with linear lobes and loose clusters of hairy, red or pink flowers.
Description
Grevillea plurijuga is a prostrate to low-lying or dense mounded to erect shrub that typically grows to a height of Шаблон:Cvt and up to Шаблон:Cvt wide. Its leaves are Шаблон:Cvt long and mostly divided with 8 to 24 linear lobes Шаблон:Cvt long and Шаблон:Cvt wide, the edges rolled under, enclosing the lower surface apart from the mid-vein. The flowers are arranged in loose, more or less cylindrical clusters of 8 to 40 on a hairy rachis Шаблон:Cvt long. Flowering time and colour varies with subspecies and the fruit is a glabrous, prominently ridged follicle Шаблон:Cvt long.[1][2]
Taxonomy
Grevillea plurijuga was first formally described in 1864 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by George Maxwell.[3][4] The specific epithet (plurijuga) means "more yokes", referring to the many leaf lobes.[5]
In 2000, Robert Owen Makinson described two subspecies of G. plurijuga in the Flora of Australia, and the names are accepted by the Australian Plant Census:
- Grevillea plurijuga F.Muell subsp. plurijuga[6] is a prostrate to low-lying, dense, mounded shrub Шаблон:Cvt high with pale grey to pinkish-red and cream-coloured flowers from September to January. The flowers are mostly borne on long, trailing peduncles below the base of the foliage.[7][8]
- Grevillea plurijuga subsp. superba (Olde & Marriott) Makinson[9] (originally described in 1993 by as Grevillea superba in the journal Nuytsia by Peter Olde and Neil Marriott)[10][11] is a dense, robust shrub Шаблон:Cvt high usually with pale grey and cream-coloured or pale yellow flowers from October to December. The flowers are mostly borne on erect peduncles held above the foliage.[12][13]
Distribution and habitat
Subspecies plurijuga grows in a range of habitats including heath, woodland and mallee between Norseman, Peak Charles, Esperance, and Cundeelee with and outlier near Southern Cross, in the Coolgardie, Esperance Plains and Mallee bioregions.[7][8] Subspecies superba grows in shrubland between Grasspatch, Scaddan, the Wittenoom Hills and Mount Ney north of Esperance in the Coolgardie, Esperance Plains and Mallee bioregions of southern Western Australia.[12][13]
Conservation status
Both subspecies of G. plurijuga are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[7][12]
