|discussion=<p>Although previously applied only to collections from Chihuahua, Mexico, <i>Potentilla townsendii</i> is here used to accommodate most plants from Arizona and New Mexico previously placed in <i>P. glaucophylla</i> (as P. diversifolia Lehmann). Plants have narrow, shallowly toothed leaflets; stems, petioles, and leaflet veins that are often reddish; and larger anthers than <i>P. glaucophylla</i>. As now circumscribed, <i>P. townsendii</i> is known in the United States primarily from the White Mountains of east-central Arizona and the high mountains of northern New Mexico. Whether these plants are truly conspecific with those from Chihuahua, Mexico, remains to be confirmed. The species might also occur in Colorado and Utah, but the best disposition of these problematic populations is uncertain. Somewhat hairy plants with subpalmate leaves are interpreted as introgression from <i>P. hippiana</i> or other species.</p>
