Potentilla crantzii is primarily European, not restricted to coasts as in North America. The nomenclatural history is long and complex (A. Kurtto et al. in J. Jalas et al. 1972+, vol. 13), with P. alpestris and P. maculata in greatest historical use. The name P. ×protea Soják is available for presumed hybrids between P. crantzii and P. hyparctica.

The emphasis on two-ranked leaves to distinguish Potentilla crantzii from P. verna follows J. Soják (pers. comm.). Some collections of P. crantzii from Newfoundland approach P. verna in their more elongate caudex branches and shorter stature.

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.
