Of conservation concern.

Potentilla arizonica is known only from the Garland Prairie area in Coconino County. Although commonly included within P. plattensis (for example, N. H. Holmgren 1997b; B. C. Johnston 1980; T. H. Kearney and R. H. Peebles 1951), P. arizonica differs in its longer hairs, more erect habit, more condensed inflorescences, pedicels that remain straight in fruit, and significantly larger anthers.

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.
