Rose family (Rosaceae)
Wooly Cinquefoil (Potentilla hippiana) likes dry sites, its flower stems are from a few inches to twenty inches tall, and its leaves are green on top and silvery hairy on the back. Leaves often curl, and, very important in identifying this species, its leaves are , arranged ladder-like rather than (as in the also very common cinquefoil, P. gracilis). Wooly Cinquefoil is a very common Potentilla in the mountains of Colorado.
Johann Georg Lehmann (1792-1860) named this species in 1827 from a specimen collected by Edwin James in 1820 near the "sources of the Platte." Carl Hippio was a colleague of Lehmann.
