Discussion

Varieties 3 (3 in the flora).

Potentilla concinna is a relatively widespread, low-growing, early-blooming species with palmate to subpalmate, abaxially cottony leaves. Flowers often appear before leaves are fully expanded. The three varieties treated here have some level of biogeographic identity and are, therefore, given provisional taxonomic recognition. Some treatments have also included P. bicrenata, P. johnstonii, and P. macounii as varieties of P. concinna. Two Mexican species, P. leonina Standley and P. oblanceolata Rydberg, have also been treated as varieties of P. concinna by J. Soják (2006); they are retained as distinct species here, pending further research on Mexican Potentilla. Two other erstwhile varieties of P. concinna are now placed in separate sections: var. modesta (Rydberg) S. L. Welsh & B. C. Johnston (misapplied) in sect. Rubricaules as P. modesta, and var. rubripes (Rydberg) C. L. Hitchcock in sect. Subjugae, intermediate between P. saximontana and P. subjuga. Potentilla concinnaeformis Rydberg, considered to be a close relative of P. concinna by I. W. Clokey (1939), is more likely a hybrid between P. glaucophylla (sect. Graciles) and P. hippiana (sect. Leucophyllae). Hybrids also occur with P. multisecta, and probably other species as well.

Potentilla concinna was first described in 1818 as P. humifusa Nuttall, a later homonym for P. humifusa Willdenow.

Variety concinna is the compact phase of Potentilla concinna with strictly palmate, short-toothed leaves that are often prominently bicolored. The variety occurs primarily in vernally wet meadows and similar situations in the Rocky Mountains of Colorado and New Mexico, and in forested areas of northern Arizona. Plants referable to var. concinna also extend into the primary range of var. dissecta (S. Watson) B. Boivin at least as far as Alberta and North Dakota. No vouchers have been located to confirm reports from Idaho (R. J. Davis 1952; B. C. Johnston 1980). The low elevation extreme is from Alberta; the highest elevations are in Colorado and Wyoming.
