Acacia johannis is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area of north eastern Australia.
The shrub typically grows to a height of around 2 m (6 ft 7 in) and has red-brown coloured glabrous and lenticellate branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, glabrous and sickle shaped phyllodes have a narrowly elliptic shape and are 14 to 18 cm (5.5 to 7.1 in) in length and 5 to 14 mm (0.20 to 0.55 in) wide and have three or four prominent longitudinal nerves with indistinct secondary nerves. It blooms in February and April producing simple inflorescences that occur singly or in pairs with flower-heads that contain 50 lemon-yellow coloured flowers.[1]
Taxonomy
The species was first formally described by the botanist Leslie Pedley in 1999 as part of the work Notes on Acacia (Leguminosae: Mimosoideae) chiefly from northern Australia as published in the journal Austrobaileya. It was reclassified by Pedley in 2003 as Racosperma johannis then returned to genus Acacia in 2006.[2]
