Acacia leprosa

Acacia leprosa, also known as cinnamon wattle, is an acacia native to Australia. It occurs in woodland in Tasmania, New South Wales and Victoria. It occurs as a hardy shrub or small tree. The phyllodes (a modified flat leaf-like structure arising through an expanded petiole replacing the leaf blade) are 3–14 cm long and contain oil glands. The lemon-yellow flowers occur as globular heads in clusters in the leaf axils. The fruit is flat seed pod.

It was discovered northeast of Melbourne in 1995, and released commercially in 2001. Acacia leprosa is mentioned in The Australasian Sketcher of Saturday 19 June 1880 in part two of an article on the Mallee Country,^[2] as one of the "beautiful shrubs"^{[citation needed]} found in the region and identified by Mr Guilfoyle, director of the Melbourne Botanic Gardens.^[3]
