--><p><i>Potentilla arizonica</i> is known only from the Garland Prairie area in Coconino County. Although commonly included within <i>P. plattensis</i> (for example, N. H. Holmgren 1997b; B. C. Johnston 1980; T. H. Kearney and R. H. Peebles 1951), <i>P. arizonica</i> differs in its longer hairs, more erect habit, more condensed inflorescences, pedicels that remain straight in fruit, and significantly larger anthers.</p>
