Acacia adsurgens, commonly known as whipstick wattle or sugar brother,[3] is a species of flowering plant in the family Fabaceae and is endemic to northern areas of Australia. It is a spreading shrub with many stems, flat, linear phyllodes, densely-flowered spikes of yellow flowers, and linear, paper-like or crusty pods.
Acacia adsurgens is a spreading, multi-stemmed shrub that typically growing to a height of 1.5–4 m (4 ft 11 in – 13 ft 1 in)[4] and has smooth, greyish-brown bark that splits to reveal reddish bark. It has flat, linear, straight or upwardly-curved phyllodes, mostly 100–180 mm (3.9–7.1 in) long and 2.0–4.5 mm (0.079–0.177 in) wide.[3][5][6]
The flowers are arranged in densely-flowered, cylindrical spikes 8–25 mm (0.31–0.98 in) long on glabrous peduncles 5–15 mm (0.20–0.59 in) long. Flowering occurs from February or March to July,[4] and the pods are linear, light brown, papery or crust-like, 35–120 mm (1.4–4.7 in) long and 2.0–3.5 mm (0.079–0.138 in) wide. The seeds are dark brown to blackish, 3.0–4.5 mm (0.12–0.18 in) long with a white to yellow or brownish aril.[3][4][5]
Taxonomy
Acacia adsurgens was first formally described in 1927 by the botanists Joseph Maiden and William Blakely in the Journal of the Royal Society of Western Australia.[7][8]
