Description
editAcacia amanda is an erect, often multi-stemmed shrub which grows to a height of 0.4–2 m (1 ft 4 in – 6 ft 7 in). Its branchlets are smooth, and have a waxy bloom. Its phyllodes are thinly leathery, narrowly elliptic to elliptic, straight to strongly curved, 38–124 mm (1.5–4.9 in) long and 8–36 mm (0.31–1.42 in) wide with three main veins. The flowers are golden yellow and arranged in spherical heads of 35 to 53, the heads in racemes 75–180 mm (3.0–7.1 in) long, with up to 3 heads in each axil, on a peduncle 15–35 mm (0.59–1.38 in) long. Flowering occurs from May to November and the fruit is a glabrous, papery, narrowly oblong pod 42–110 mm (1.7–4.3 in) long and 7–13 mm (0.28–0.51 in) wide, and prominently raised over the seeds. The seeds are 6.0–7.5 mm (0.24–0.30 in) long.[3][4]
Taxonomy
editAcacia amanda was first formally described in 2001 by Gregory John Leach in the Flora of Australia from specimens he collected near the track to Jarrangbarnmi (Koolpin Gorge), in Kakadu National Park.[5] The specific epithet (amanda) honours Leach's wife.[4]
This wattle is included in Subgenus Phyllodineae, section Plurinerves.[6]
Distribution
