|discussion=<p>Variety blancheae grows primarily in chaparral in coastal southern California from San Luis Obispo to San Diego counties (rare in northern Baja California, Mexico) and on adjacent Santa Catalina, Santa Cruz (where frequent), and Santa <i>Rosa</i> (rare) islands. This treatment combines the coastal mainland and insular plants. Both tend to have multiple flowers on each short shoot and coiled hairs on young stems, leaves, hypanthia, and pedicels. This coiled hair type is consistent in mainland populations; some insular plants are sericeous throughout. Insular plants typically have larger leaves than mainland plants, except in very dry areas, and conversely, mainland coastal plants previously designated as <i></i>var.<i> betuloides</i> have smaller leaves except in protected and shaded habitats. Recognition of these two as distinct, at any rank, is poorly supported, and the authors consider them phases of a single taxon. Plants of the more arid slopes in transmontane southern and central California are more sericeous throughout and have fewer flowers per short shoot (see <i></i>var.<i> betuloides</i>). Intermediates occur in zones of contact.</p>
