Cassinia aureonitens explained

Cassinia aureonitens, commonly known as the yellow cassinia[1] is a species of flowering plant in the family Asteraceae and is endemic to eastern New South Wales. It is a shrub with elliptic leaves and heads of yellow flowers arranged in dense corymbs.

Description

Cassinia aureonitens is a shrub that typically grows to a height of, its branches covered with glandular hairs. The leaves are elliptic, long and wide, dark green on the upper surface and paler below. The flower heads are long and about in diameter, each with five or six yellow florets surrounded by four or five overlapping whorls of involucral bracts. The heads are arranged in a dense corymb up to in diameter. Flowering occurs in spring and summer and the achenes are about long with a pappus about long.

Taxonomy

Yellow cassinia was first formally described in 1818 by Robert Brown and given the name Cassinia aurea in the Transactions of the Linnean Society of London,[2] [3] but the name was illegitimate because Brown had used the same name in 1813 for a different species now known as Angianthus tomentosus.[4] [5] [6] In 1951 Norman Arthur Wakefield designated the name Cassinia aureonitens for this species, publishing the new name in The Victorian Naturalist.[7] [8]

Distribution and habitat

Cassinia aureonitens grows in heath and woodland on the coast of New South Wales between Taree and Eden and inland to the Central Tablelands.
