Grevillea nana, commonly known as dwarf grevillea, 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.
Grevillea nana is a prostrate to dense, mounded shrub that typically grows to high and wide. Its leaves are 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 long, and are silky- to woolly-hairy on the outside, the colour varying with subspecies, the pistil long. Flowering time also varies with subspecies, and the fruit is a hairy follicle long.[1]
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.[2] [3] The specific epithet (nana) means "dwarf".[4]
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:
Subspecies abbreviata grows on shallow soil around granite outcrops in shrubland in the area around Wubin and about 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..
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, meaning that it is poorly known and from only one or a few locations.[9]
