Шаблон:Short description Шаблон:Speciesbox
Grevillea preissii is a species of flowering plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is a mounded to spreading or dense, erect shrub, the leaves divided with 5 to 7 linear to more or less cylindrical lobes, and groups of reddish flowers arranged along one side of the flowering rachis.
Description
Grevillea preissii is a mounded to spreading shrub that typically grows to a height of Шаблон:Cvt or a dense, erect shrub to Шаблон:Cvt and usually has woolly- or shaggy-hairy branchlets. The leaves are Шаблон:Cvt long and divided, usually with 5 to 7 linear to more or less cylindrical lobes Шаблон:Cvt long and Шаблон:Cvt wide. The edges of the leaves are rolled under, obscuring most of the lower surface. The flowers are arranged in groups of 12 to 30 on one side of a rachis Шаблон:Cvt long and are red, orange-red or pinkish red, the pistil Шаблон:Cvt long. Flowering mainly occurs from May to October and the fruit is an oval follicle about Шаблон:Cvt long.[1][2]
Taxonomy
Grevillea preissii was first formally described in 1845 by Carl Meissner in Johann Georg Christian Lehmann's Plantae Preissianae.[3][4] The specific epithet (preissii) honours Ludwig Preiss.[5]
In 1994, Peter M. Olde and Neil R. Marriott described two subspecies of G. preissii and the names are accepted by the Australian Plant Census:
- Grevillea preissii subsp. gabrilimba Olde & Marriott[6] usually has shaggy-hairy young leaves and branchlets, leaves usually Шаблон:Cvt long, the floral rachis and outside of the flowers more or less glabrous.[7][8]
- Grevillea preissii Meisn. subsp. preissii[9] usually has silky- to woolly-hairy young leaves, branchlets, and floral rachis, the leaves usually Шаблон:Cvt long, and the outside of the flowers sparsely hairy.[10][11]
Distribution and habitat
Grevillea preissiisubsp. glabrilimba grows in low heath, in near-coastal areas between Green Head and Leeman and subsp. preissii is found in coastal areas between Lancelin and Bunbury, in the southwest of Western Australia.[7][8][10][11]
Conservation status
Bothe subspecies of G. preissii are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[7][10]
