On serpentine soil in Siskiyou Mountains. Elaborate and distinctive structure at base of leaves in photo 4.
FNA's description of P. versicolor says it should only have 3-6 leaflets on each side. Maybe that's not quite right?
Sample 1
This potentilla was mixed in clumps with another species, P. flabellifolia.
I did not record which bees were collected from which species.
