Grevillea floribunda, commonly known as seven dwarfs grevillea, [3] is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is a spreading shrub with oblong to egg-shaped leaves with the narrower end towards the base and groups of six to twenty flowers covered with rusty brown hairs.

Description

Grevillea floribunda is a spreading shrub that typically grows to a height of 0.4–1.8 m (1 ft 4 in – 5 ft 11 in). Its leaves are oblong to egg-shaped, mostly 20–80 mm (0.79–3.15 in) long and 2–20 mm (0.079–0.787 in) wide and softly-hairy on the lower surface. The flowers are arranged in groups of six to twenty, usually at the end of branches, the perianth is greenish and covered with woolly, rusty-brown hairs and the pistil is 9.0–19.5 mm (0.35–0.77 in) long. The ovary is sessile and the style is reddish. Flowering occurs in all months with a peak in spring and the fruit is a hairy follicle 10.5–17 mm (0.41–0.67 in) long. [3] [4] [5] [6]

Taxonomy

Grevillea floribunda was first formally described in 1830 by Robert Brown in his Supplementum primum Prodromi florae Novae Hollandiae . [7] [8] The specific epithet means "profusely flowering". [9]

In 1994, Peter M. Olde and Neil R. Marriott described two subspecies of G. floribunda and the names are accepted by the Australian Plant Census:

Distribution and habitat

Seven dwarfs grevillea grows in forest and woodland and is widespread on the tablelands and western slopes of New South Wales and in south-eastern Queensland. [3] [14] There is a single doubtful record from the Killawarra Forest in Victoria. [4] Subspecies tenella is restricted to the Darling Downs region of Queensland. [13]

Conservation status

Grevillea floribunda is currently listed as Least Concern on the IUCN Red List of Threatened Species. It is an extremely widespread and common species with a stable overall population and no known major threats. Minor, localised threats include inappropriate fire regimes and land clearing for agriculture. [1]
