Leaves of acmispon oroboides
are divided into between three and six narrow leaflets, appearing palmate from a distance, but the attachment points are slightly separated, giving a pinnate arrangement, with the leaflets often irregularly positioned. Leaflet tips may be rounded or pointed. Leaves grow on short stalks. The branched stems are decumbent or lie along the ground, have a covering of appressed hairs, and reach lengths of up to 16 inches. Plants produce many stems, radiating from the base.
Flowers are attached by appressed-hairy stalks up to 2.5 inches in length (longer than the leaves), produced singly or in pairs. The five sepals are divided at the tip into up to three narrow lobes. The corolla is about 0.7 inches long, and the petals are yellow, crossed with thin red veins. The narrow, strigose seed pods are straight to curved, around one inch long.
