Correa lawrenceana var. lawrenceana is the implicit autonym of Correa lawrenceana and is endemic to Tasmania. It is a shrub with papery, oblong leaves and pale green, narrow cylindrical flowers arranged singly on the ends of branchlets.

Description

Correa lawrenceana var. lawrenceana is a shrub that typically grows to a height of 4 m (13 ft) and has papery, oblong leaves 20–40 mm (0.79–1.57 in) long, 3–30 mm (0.12–1.18 in) wide and sometimes covered with rust-coloured hairs on the lower surface. Specimens in the north-east of the state have narrow leaves, while those from the south and west have wider leaves with hairy undersides. The flowers are borne singly on the ends of branchlets on a stalk about 5 mm (0.20 in) long. The calyx is shortly cup-shaped, 3 mm (0.12 in) long and 4 mm (0.16 in) wide with rust-coloured hairs on the outside and with a wavy rim. The corolla is narrow cylindrical, 15–20 mm (0.59–0.79 in) long, pale green and covered with soft hairs. Flowering mostly occurs in spring.[2][3][4]

Taxonomy

Correa lawrenceana was first formally described in 1834 by William Jackson Hooker who published the description in his journal, The Journal of Botany.[5][6] In 1855, his son Joseph Dalton Hooker described Correa lawrenceana var. glabra, implicitly creating the autonym C. lawrenceana var. lawrenceana.[7]

Distribution and habitat

This variety of C. lawrenceana grows in forest, mainly in mountainous areas in Tasmania, including on King Island.[2][3] The variety is also listed as occurring in the Australian Capital Territory.[8]
