The palmate leaf of this very common Potentilla quickly distinguishes it from the ladder-like arrangement of leaves on P. hippiana, another very common Potentilla.  P. Pulcherrima often grows to nearly two feet (although it commonly reclines, as in this picture) and is the most common Potentilla species in high mountain meadows.  Notice that these "cinque"-foil leaves actually have seven, not five, divisions, probably the result of the common hybridization of P. hippiana and P. pulcherrima. 

"Pulcherrima" is Latin for "beautiful split", perhaps referring to the attractive leaves. The seeds of this species were first collected for science by David Douglas from plants "on the banks of the Columbia and the plains of the Multnomah rivers"  and were then grown in England.  Douglas named the plant Potentilla gracilis in 1830. The plant has endured dozens of name changes since then; the name Potentilla pulcherrima was given it in 1830 from a specimen collected by Thomas Drummond in Canada, in about 1830.

The silvery-haired backside, evenly toothed margins, and shiny green top-side of P. pulcherrima help identify it. (The red runners in both photographs and the tri-foliate leaves in the bottom photograph, are those of Wild Strawberry.)
