Cassinia longifolia

Cassinia longifolia, commonly known as shiny cassinia, is a species of flowering plant in the family Asteraceae and is endemic to eastern Australia. It is an erect, aromatic shrub with sticky, hairy foliage, linear or oblong to narrow lance-shaped leaves, and heads of creamy-white flowers arranged in a dense corymb.

Description
Cassinia longifolia is an erect, aromatic shrub that typically grows to a height of 1.2–2.5 m, its foliage covered with short, glandular hairs and sticky. The leaves are linear or oblong to narrow lance-shaped, 15–95 mm long and 2–6 mm wide on a petiole 0.5–1 mm long. The upper surface of the leaves is glabrous, the edges curve downwards and the lower surface is covered with fine hairs. The flower heads are 2–3 mm long and 1.0–1.5 mm wide, each with five or six creamy-white florets surrounded by three to five overlapping rows of egg-shaped involucral bracts. The heads are arranged in a dense corymb up to 200 mm in diameter. Flowering occurs in summer and autumn and the achenes are about 0.8 mm long with a pappus 2–3 mm long.

Taxonomy and naming
Cassinia longifolia was first formally described in 1818 by Robert Brown in the Transactions of the Linnean Society of London. The specific epithet (longifolia) means "long-leaved".

Distribution and habitat
Shiny cassinia grows in forest and disturbed places, especially after fire, and often on ridges. It occurs in south-eastern New South Wales, the Australian Capital Territory and is widespread and common in eastern Victoria.
