Jacksonia humilis is a delicate, spreading to prostrate shrub that typically grows to high and wide, its branches dull green and ribbed. Its end branches are sharply-pointed phylloclades, the leaves reduced to dark brown, egg-shaped scales, long and wide with toothed edges. The flowers are scattered along the branches, each flower on a pedicel long. There are egg-shaped bracteoles long and wide on the pedicels. The floral tube is long and the sepals are membranous, the lobes long, wide and fused at the base. The standard petal is yellow-orange with red markings, long and deep, the wings yellow, yellow-orange with red markings, long, and the keel is dark red, long. The stamens have dark red filaments, long. Flowering occurs from September to November, and the fruit is a membranous, densely hairy, elliptic pod, long and wide.[1]
Jacksonia humilis was first formally described in 2007 by Jennifer Anne Chappill in Australian Systematic Botany from specimens collected east of Jerramungup in 1992.[2] The specific epithet (humilis) means 'low' or 'small'.[3]
This species of Jacksonia grows in woodland in sand or sandy clay between the southern Stirling Range to Munglinup in the Esperance Plains, Jarrah Forest and Mallee bioregions of southern Western Australia.
Jacksonia humilis is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
