Grevillea nana, commonly known as dwarf grevillea,[1] is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a prostrate to low, mounded, dense shrub with divided leaves with sharply-pointed, linear lobes, and clusters of pink, orange, yellow or red flowers.

Description

Grevillea nana is a prostrate to dense, mounded shrub that typically grows to Шаблон:Cvt high and Шаблон:Cvt wide. Its leaves are Шаблон:Cvt long and divided with 5 to 19 lobes, their size varying with subspecies. The flowers are arranged near the ground and at the base of the foliage on a rachis Шаблон:Cvt long, and are silky- to woolly-hairy on the outside, the colour varying with subspecies, the pistil Шаблон:Cvt long. Flowering time also varies with subspecies, and the fruit is a hairy follicle Шаблон:Cvt long.[1][2]

Taxonomy

Grevillea nana was first formally described in 1943 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens collected by William Blackall between Koorda and Bencubbin.[3][4] The specific epithet (nana) means "dwarf".[5]

In 1986, Donald McGillivray described two subspecies of G. nana in his book, New Names in Grevillea (Proteaceae), and the names are accepted by the Australian Plant Census:

  • Grevillea nana subsp. abbreviata McGill.[6] has leaves with 7 to 19 lobes that are usually Шаблон:Cvt long and Шаблон:Cvt wide, and green or greenish-fawn flowers with a pink to purplish style from August to October.[7][8]
  • Grevillea nana C.A.Gardner subsp. nana[9] has leaves with 5 to 13 lobes that are Шаблон:Cvt long and Шаблон:Cvt wide, and creamy-green or greenish-pink to scarlet flowers with a purplish, red or pale orange style from June to October.[10][11]

Distribution and habitat

Subspecies abbreviata grows on shallow soil around granite outcrops in shrubland in the area around Wubin and about Шаблон:Cvt to the east, in the Avon Wheatbelt bioregion. Subspecies nana grows in open heath and shrubland from near Bullfinch to Mount Gibson and Manmanning in the Avon Wheatbelt, Coolgardie, Murchison and Yalgoo bioregions of south-western Western Australia..[1]

Conservation status

Subspecies nana is listed as "not threatened" but subspecies abbreviata is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[8] meaning that it is poorly known and from only one or a few locations.[12]
