|discussion=<p><i>Malacothamnus densiflorus</i> occurs in the southern Coast Ranges. Plants with relatively short involucellar bractlets and calyx measurements in the lower range have been recognized as <i></i>var.<i> viscidus</i>; intergradation with more typical forms is complete. <i>Malacothamnus densiflorus</i> intergrades with <i>M. fasciculatus</i> at lower elevations of the coastal Peninsula Ranges in San Diego County.</p>
