|discussion=<p>Variety cognata, indistinguishable in floral characters from var. coulteri and differing in cauline leaves parted almost to midribs, occurs at some mainland sites in southern California and has been collected on the Channel Islands. In California, Malacothrix coulteri grows in the San Joaquin Valley, central western areas, western Transverse Ranges, Peninsular Ranges, and Mojave Desert. In Arizona, it grows in the Sonoran Desert in the Santa Rita and Tucson mountains, and similar places.</p>
