Discussion

Potentilla newberryi grows in valley bottoms in south-central Oregon, northeastern California, and northwestern Nevada. The only specimen supposedly collected in south-central Washington (W. N. Suksdorf 2718, WTU) was gathered in 1898.

Potentilla crinita occurs mainly in the upper foothills and mountains from southern Nevada to south-central Utah, northern Arizona, and northwestern New Mexico and is disjunct to southwestern Colorado (Archuleta County). It tends to grow on somewhat drier, rockier sites than co-occurring species of Potentilla. The often conduplicate leaflets, falcate in outline, bear relatively few, small teeth. Two varieties are sometimes recognized, based on leaflet and vestiture characters that do not reliably coincide.

Potentilla crinita can hybridize with P. hippiana where the two species overlap, in spite of ecological partitioning. N. H. Holmgren (1997b) noted the type of P. crinita may be such a hybrid. If correct, then P. lemmonii would be used for the species unless the name P. crinita were to be conserved with a conserved type.
