Acacia courtii, also commonly known as Northern Brother wattle or North Brother wattle, [1] is a tree belonging to the genus Acacia and the subgenus Juliflorae that is native to eastern Australia. It is currently listed as vulnerable by the Environment Protection and Biodiversity Conservation Act 1999 . [1]
The tree typically grows to over 7 m (23 ft) [1] to a maximum height of 20 m (66 ft) and has slender, brittle and pendulous branchlets with caducous and deltate stipules that have a length that is mostly less than 0.5 mm (0.020 in). Like most species of Acacia it has phyllodes rather than true leaves. The glaucous, evergreen and flexible phyllodes have a linear shape and straight with a small hook at the end. They have a length of 5 to 18 cm (2.0 to 7.1 in) and a width of 5 to 12 mm (0.20 to 0.47 in) and have one prominent vein with several others. It blooms between November and January producing inflorescences with paired or solitary flower-spikes that have cylindrical shape with a length of 3 to 6.5 cm (1.2 to 2.6 in) with loosely packed golden coloured flowers. After flowering straight woody seed pods form that have a linear shape. The shiny brown seeds inside have an oblong-elliptic shape and a length of 5.5 to 7.8 mm (0.22 to 0.31 in) with a filiform funicle that is folded four to eight times and a small oblique aril. [2]
