Of conservation concern.

Potentilla cristae is known only from Cory Peak, Mount Eddy, and the Marble Mountains in northwestern California. In addition to the characteristics in the key, the species is distinctive in having a low dorsal crest on the achenes, hence the specific epithet.

Key
1. Leaves often notably seasonally dimorphic; leaflets: early-season evenly to unevenly incised 1/2–3/4 to midvein (sometimes deeply lobed as well), teeth 3–7 per side (sometimes secondarily toothed); late-season evenly incised 1/5–1/4 to midvein, teeth 6–9 per side; petioles: long hairs 1–1.5(–3) mm; n Arizona and New Mexico, barely entering Colorado.
var. subviscosa
1. Leaves not notably seasonally dimorphic; leaflets ± evenly incised 1/4–1/2 to midvein, teeth 2–4(–6 in late-season) per side; petioles: long hairs 2–3(–4) mm; Santa Catalina and Rincon mountains and Sierra Ancha, se Arizona.
