Description edit
Grevillea banyabba is an open shrub that typically grows to a height of 0.8–1.5 m (2 ft 7 in – 4 ft 11 in), its branchlets covered with long, fine hairs. It has simple, narrowly egg-shaped leaves, 25–38 mm (0.98–1.50 in) long and 5–10 mm (0.20–0.39 in) wide with the edges slightly turned down and silky hair on the lower surface. The flowers are arranged in groups near the ends of branches or in leaf axils, each group with six to fourteen flowers on a rachis 8–15 mm (0.31–0.59 in) long, and are red with a green base. The pistil is 25–27 mm (0.98–1.06 in) long and covered with long, fine hairs. Flowering mostly occurs from August to October and the fruit is a follicle with a few long, soft hairs, and that splits down one side to release flat, winged seeds.[3][4][5][6][7]
Taxonomy edit
Grevillea banyabba was first formally described in 1994 by Peter M. Olde and Neil R. Marriott in the journal Telopea, based on plant material near Grafton in 1992.[7][8] The specific epithet (banyabba) refers to the Banyabba Nature Reserve, to which this species is mostly confined.[7]
Distribution and habitat edit
Banyabba grevillea grows in sandy soil on or near the tip of ridges in forest, mostly in the Banyabba Nature Reserve north-west of Grafton.
Conservation status edit
This grevillea is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999, the New South Wales Government Biodiversity Conservation Act 2016 and the IUCN Red List of Threatened Species. It has a restricted distribution and a small population of approximately 800 to 2000 individuals.[3][6][1]
