|discussion=<p>Variety flabelliformis is relatively distinctive, perhaps on par with members of sect. Graciles treated here as species. Plants are relatively large, with deeply incised leaves that are notably bicolored with dense cottony hairs abaxially. There are two morphs with some geographic underpinning, possibly deserving taxonomic recognition. One morph, characteristic of the northern prairies and including the type, has simply pectinate leaves with a very narrow undivided medial blade and narrow teeth lacking secondary toothing. The second morph tends to have unevenly incised leaves with a wider undivided medial blade and teeth that are often tapering and secondarily toothed. This morph is centered in the montane valleys of the northern Rocky Mountains, extending as far south as Modoc County in northeastern California.</p><!--
--><p>Collections of <i></i>var.<i> flabelliformis</i> from eastern locations (Michigan, Minnesota, Wisconsin) are probably introductions, possibly of uncertain persistence. Historical reports from Alaska, Colorado, Nebraska, and <i>Nevada</i> are unconfirmed as this variety.</p><!--
--><p>Although <i>Potentilla</i> flabelliformis <i></i>var.<i> ctenophora</i> Rydberg [= <i>P. gracilis</i> <i></i>var.<i> ctenophora</i> (Rydberg) B. Boivin] is commonly treated as a synonym of P. flabelliformis, P. A. Rydberg (1908d) had placed it in synonymy under P. blaschkeana (addressed here under <i></i>var.<i> gracilis</i>). Rydberg (1897, 1898) did not designate a type or syntypes, so the proper disposition of <i></i>var.<i> ctenophora</i> awaits lectotypification.</p>
