Acacia johnsonii, commonly known as gereera wattle or geereva wattle,[1][2] is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is native to parts of eastern Australia .
Description
The shrub typically grows to a height of 1.5 to 3 m (4 ft 11 in to 9 ft 10 in) and has slightly resinous and hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The flat evergreen patent to erect phyllodes have a linear to narrowly linear shape and are straight to shallowly incurved. The glabrous green phyllodes have a length of 1 to 3 cm (0.39 to 1.18 in) and a width of 1 to 2 mm (0.039 to 0.079 in) and are usually narrowed toward the base with one to three indistinct nerves.[2] It blooms between August and October[1] producing simple inflorescences that occur singly in the upper axils, the spherical flower-heads contain 20 to 30 golden coloured flowers.[2]
Taxonomy
The specific epithet honours the collector of the type specimen, Robert William Johnson, who collected it in 1963 from an area to the north of Chinchilla. Johnson was also once the Director of the Queensland Herbarium.[1]
Distribution
The shrub has a wide distribution through south eastern Queensland and central New South Wales.[2] It is commonly situated on sand-plains growing in sandy soils as a part of spinifex communities.[1]
