Cassinia leptocephala is a species of flowering plant in the family Asteraceae and is endemic to New South Wales. It is a large, woody shrub with hairy, reddish stems, stiff linear leaves, and heads of pale yellow flowers arranged in a dense corymb.

Description

Cassinia leptocephala is a robust, woody shrub that typically grows to a height of up to Шаблон:Cvt and has reddish stems densely covered with yellowish glandular hairs. The leaves are stiff, linear, Шаблон:Cvt long and Шаблон:Cvt wide with the edges rolled under. The base of the leaves is stem-clasping and the lower surface is scaly and covered with glandular hairs. The flower heads are Шаблон:Cvt long and about Шаблон:Cvt wide, each with two or three pale yellow florets surrounded by three or four overlapping rows of involucral bracts. The heads are arranged in a dense corymb up to Шаблон:Cvt in diameter. The achenes are about Шаблон:Cvt long with a pappus about Шаблон:Cvt long.[1]

Taxonomy and naming

Cassinia leptocephala was first formally described in 1863 by Ferdinand von Mueller in Fragmenta phytographiae Australiae.[2][3]

In 2004, Anthony Edward Orchard described two subspecies in Australian Systematic Botany, and the names are accepted by the Australian Plant Census:

  • Cassinia leptocephala subsp. everettiae Orchard[4] has woolly involucral bracts;[1]
  • Cassinia leptocephala Orchard subsp. leptocephala[5] has more or less glabrous bracts.[1]

Distribution and habitat

This cassinia grows in forest, from the Sydney region to the New England National Park and west to the Warrumbungle Range in New South Wales.[1] Subspecies everettiae is restricted to the Warrumbungle Range.[6]
