MASLIN, B.R. AND COWIE, I.D.
Acacia equisetifolia Maslin & Cowie, a new species known only from Kakadu National Park, Northern Territory, is described. The new species, formerly known by the phrase name Acacia sp. Graveside Gorge (V.J. Levitzke 806), is very closely related to A. hippuroides Heward ex Benth. which occurs about 1,000 km to the south-west, in the western Kimberley region of Western Australia. The main morphological features separating these two species are the nature of branchlet and peduncle indumentum and various pod attributes.
