Grevillea pauciflora, commonly known as the few-flowered grevillea, [2] or as Port Lincoln grevillea in South Australia, [3] is a species of flowering plant in the family Proteaceae and is endemic to the south of continental Australia. It is an erect to straggly or spreading shrub with linear to narrowly wedge-shaped leaves and red or orange flowers with a red or orange style.

Description

Grevillea pauciflora is an erect to straggly or spreading shrub that typically grows to a height of 0.2–2 m (7.9 in – 6 ft 6.7 in). Its leaves are linear or narrowly wedge-shaped to egg-shaped with the narrower end towards the base, mostly 20–50 mm (0.79–1.97 in) long and 2.5–8 mm (0.098–0.315 in) wide with the edges turned down or rolled, the lower surface sometimes silky hairy. The flowers are arranged singly or in groups of up to four, sometimes to ten, on the ends of branches or in leaf axils on a rachis 0.2–1.5 mm (0.0079–0.0591 in) long. The flowers are red or orange with a red or orange style, the pistil 7–10.5 mm (0.28–0.41 in) long. Flowering time varies with subspecies and the fruit is a glabrous, elliptic follicle 10–14 mm (0.39–0.55 in) long. [3] [2] [4]

Taxonomy

Grevillea pauciflora was first formally described in 1810 by Robert Brown in Transactions of the Linnean Society of London . [5] [6] The specific epithet (pauciflora) means "few-flowered". [7] The specific epithet pauciflora, referring the Latin term for 'few flowered'. [8] [9]

In 1986, Donald McGillivray described two subspecies in New Names in Grevillea (Proteaceae) and in 1996 William Robert Barker described a third subspecies in the Journal of the Adelaide Botanic Gardens , [10] and the names are accepted by the Australian Plant Census:

Distribution and habitat

Grevillea pauciflora grows in sandy soil. Subspecies leptophylla is only known on the Eyre Peninsula in South Australia, where it is found north and north-west of Cummins, but subsp. pauciflora is widespread on the Eyre and Yorke Peninsulas and on Kangaroo Island. Subspecies psilophylla is found in near-coastal areas of Western Australia from east of Esperance to Point Malcolm near Israelite Bay and subspecies saxatilis only grows in Cape Arid National Park.
