|discussion=<p><i>Potentilla furcata</i> 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 <i>P. rubricaulis</i> in having less open inflorescences, smaller flowers, narrower petals, more papillae on styles, and denser glands on epicalyx and calyx.</p>
