|discussion=<p><i>Potentilla wheeleri</i> is found in the southern Sierra <i>Nevada</i> and San Bernardino Mountains of southern California. Compact plants on the summit of Mount San Gorgonio, described by Jepson as var. paupercula, show no consistent difference to justify their taxonomic segregation. Variety viscidula Rydberg has been misapplied to Arizona populations now called <i>P. rhyolitica</i>. Plants identified as <i>P. wheeleri</i> (excluding <i>P. rimicola</i>) from the Sierra San Pedro Mártir (Baja California) stand as a distinct species, P. luteosericea Rydberg (= <i>P. pinetorum</i> Wiggins).</p>
