Jacksonia rhadinoclada is a spreading to prostrate, delicate shrub that typically grows up to high and wide. It has many dull green branches, the end branches sharply-pointed phylloclades, its leaves reduced to egg-shaped, black scales, long and wide with toothed edges.

This species of Jacksonia grows on sand or brown clay-loam in shrubland or woodland in inland areas of Western Australia between Pindar and Bencubbin in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains and Yalgoo bioregions of Western Australia.
Jacksonia rhadinoclada is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
