is one of the few yellow-flowered members of this genus; most are white. The branched stems may be up to 20 inches long, but usually grow along the ground, forming low mats. All plant parts are hairless. The fleshy leaves grow in a basal rosette and along the stem; those at the base are pinnately lobed (three to nine pairs, with entire margins), while stem leaves are simple, and shorter, with either entire or shallowly-toothed margins. Leaves are attached by short stalks.
Flowers are very small; the ovate, light green sepals are around 1/20 of an inch in length, and the spatulate, clawed petals are about twice as long. The flower center contains six stamens, shorter than the petals.
