Melaleuca scabra, commonly known as rough honey-myrtle is a shrub in the myrtle family, Myrtaceae, and is endemic to the south of Western Australia. It is a woody shrub with unusual leaves and profuse pink to purple heads of flowers from mid-winter to mid-summer, although the flowers are not long-lasting. It was formerly assumed to be a widespread species until the genus was revised in 1999 by Lyndley Craven and Brendan Lepschi. In Flora Australasica of 1828, Robert Sweet described this species as "a rare and beautiful plant" and "...its flowers are of a dark purple and produced in great abundance; the ends of all the young shoots being covered with them, they are there crowded in dense heads, so that they have scarcely room to expand, and are of a pleasant aromatic scent."
