Description

Maireana obrienii is an erect shrub that typically grows to a height of up to 80 cm (31 in) and has glabrous branchlets, except for tufts of hairs in leaf axils. The leaves are arranged alternately and fleshy, narrowly oval to club-shaped, mostly 3–6 mm (0.12–0.24 in) long and glabrous. The flowers are bisexual, the fruiting perianth 10–13 mm (0.39–0.51 in) in diameter with a thin-walled, shallowly hemispherical tube 3.5–4.5 mm (0.14–0.18 in) high in diameter with a more or less flat wing with a rosy-pink margin and a radial slit.

Taxonomy

Maireana obrienii was first formally described in 2013 by Neville Walsh in the journal Muelleria . [2] [5] The specific epithet (obrienii) honours "Mr Eris O'Brien, farmer and naturalist, whose extensive knowledge of the vegetation of the Riverina has resulted in many new discoveries". [2]

Distribution and habitat

This species of bluebush grows in grassland and open woodland, and occurs in southern Queensland and in an arc from near Jerilderie in New South Wales and west to Serpentine and between Inglewood, Echuca and Bendigo in Victoria. [2] [3] [4]
