Could be mistaken for Lomatium foeniculaceum, both are yellow-flowered, low growing plants in the Parsley family, share the same habitat, and bloom at the same time. However, Lomatium foeniculaceum has hairy stems and leaves, and its stems are cylindrical in profile. While Musineon divaricatum has stems and leaves that are glabrous, and its stems are concave in profile.
