It is a shrub with a curry-like odour, crowded linear leaves, and heads of creamy-white flowers arranged in panicles.
Cassinia laevis is a shrub that typically grows to a height of, has erect, densely branched stems and a curry-like odour. The leaves are crowded, linear, long and about wide. The upper surface of the leaves is shiny but the lower surface has fine hairs although obscured by the rolled edges of the leaf. The flower heads are long and wide, arranged in pyramid-shaped panicles in diameter, each head with two to four creamy-white florets surrounded by involucral bracts in four or five whorls. Flowering occurs spring and autumn and the achenes are about long with a pappus about long.[3]
Cassinia laevis was first formally described in 1818 by Robert Brown in the Transactions of the Linnean Society of London.[4] [5] The specific epithet (aculeata) means "smooth".[6]
Cassinia laevis is widespread in Queensland, New South Wales and eastern South Australia. There are also records from the Northern Territory. It grows in a wide variety of habitats, often on stony ridges and often in mallee.[7] [8]
