Potentilla furcata is a characteristic species of the steppe bluffs of interior and south-central Alaska, Yukon, and northern British Columbia, mainly within the unglaciated Beringian region. It differs from P. rubricaulis in having less open inflorescences, smaller flowers, narrower petals, more papillae on styles, and denser glands on epicalyx and calyx.

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.
