Flower color of lomatium mohavense
ranges from yellow to purple to brown. Leaves are greyish-green, and finely, pinnately divided 3 or 4 times into tiny lobes, around 1/8 of an inch long. The length of the leafy portion of the stalk is between 1 and 4 inches, generally slightly shorter than the petiole. Plants have no stem; the stalks of both leaves and flowers grow from the base. Flower stalks are thick and rigid, and like the leaves they have a covering of soft, short, light grey hairs.
Like all lomatium species, the inflorescence is a compound umbel, with 8 to 18 umbellets held on stalks (rays) up to 2 inches long. Flowers have five protruding stamens, topped by yellow-white anthers. Fruits are ovate in outline, glabrous or covered by short hairs, and have a pair of prominent wings, each about the same width as the central portion.
