Jacksonia grevilleoides is a prostrate or erect shrub that typically grows up to high and wide, its branches greyish green and prominently ribbed. Its phylloclades are irregular in size and shape, often branched, long and wide, the lobes sharply-pointed. The leaves are reduced to egg-shaped, reddish-brown scales, long and wide. The flowers are attached singly on the lobes of phylloclades on a straight pedicel long. There are egg-shaped bracteoles with toothed edges, 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 for . The standard petal is yellow-orange, rarely with red markings, long and wide, the wings yellow-orange, long, and the keel yellow-orange, long. The filaments of the stamens are greenish white, long. Flowering occurs from November to April, and the fruit is a woody, densely hairy, narrowly elliptic pod, long and wide.[1]
