|discussion=<p>Potentilla modesta is the dominant component of what has previously been called P. rubricaulis in the Intermountain Region (for example, N. H. Holmgren 1997b, including illustration). This and other species of alpine Potentilla often grow in mixed populations, which contributes to confusion and mistaken identifications. In general, P. modesta has a more compact inflorescence and more consistently palmate basal leaves than sympatric members of the section. Intergrades with P. jepsonii (sect. Pensylvanicae) can also be problematic, though leaves of the latter are generally subpinnate and abaxially grayish rather than white.</p><!--
--><p>The epithet modesta is misapplied in the combination Potentilla concinna var. modesta, which S. L. Welsh et al. (1993) used for plants mostly placed here in P. concinna var. divisa (sect. Concinnae).</p>
