Stems from a perennial root, slender, prostrate, slightly strigose or glabrate, often rooting at the 
nodes. Stipules oblong-lanceolate, mostly entire. Leaves digitately 5-foliolate ; leaflets 1-3 em. long, 
cuneate, crenate or dentate. Bractlets ovate or elliptic, much exceeding the ovate sepals. Otherwise 
as in P. Canadensis. 
This European species has been collected by Martindale in 1876 on ballast in New Jersey. It 
differs from P. Canadensis in the creeping and rooting stem, smaller leayes and large oyate or elliptic 
bractlets, which exceed the sepals.
