Discussion

In addition to the characters given in the key, Potentilla inclinata in the flora area tends to have narrower leaflets, more compact inflorescences with fewer flowers, and more coarsely hairy epicalyx bractlets and sepals than P. intermedia. The species is currently becoming more common in western North America.

The name Potentilla inclinata has been conserved over P. assurgens Villars (T. Gregor et al. 2009).
