Acacia infecunda, also known as famine wattle, is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is native to parts of south eastern Australia.
The shrub typically grows to a height of and as much as . It readily suckers and has glabrous branchlets.[1] It has linear grey-green phyllodes that are long and in width. The thin and glabrous phyllodes are straight and flat and have a non-prominent midrib and absent lateral nerves. It blooms between August and October producing simple inflorescences that occur in groups of five to ten on racemes with a length of . The spherical flower-heads have a diameter of and contain five to nine golden coloured flowers.[1]
The species was first formally described by the botanists Bill Molyneux & S. G. Forrester in 2008 as part of the work "Three new Acacia species (Fabaceae: Mimosoideae) from East Gippsland, Victoria" as published in the journal Muelleria.[2] It is closely related to Acacia boormanii which is much taller.[1]
The shrub has a limited distribution in north-western Victoria to the south of Wulgulmerang around Splitters Creek on elevated rocky areas in dry open forest communities growing in rocky shallow soils.[3] Only a single small population of fragmented stands growing in a limited area is known on the Wombargo Range in the headwaters of the Little River which is a tributary of the Snowy River.[1]
