State Rank Reason (see State Rank above)
Rare in Montana, where it is currently only from a couple collections from the Beartooth Mtns. The remote, high-elevation habitat should greatly minimize the potential for any negative impacts to the viability of the species in the state. Accurate estimates of population levels are lacking.
 
General Description
Low arctic cinquefoil is a perennial with stems 5-20 cm tall that arise from a branched rootstock covered by old reddish-brown leaf bases. The basal leaves have long petioles and blades with three coarsely-toothed leaflets; the stems have a few small, sessile leaves or leaf-like bracts and 1-3 flowers borne on short stalks. Foliage is loosely covered by long hairs that remain on the plant as it ages. The flowers are 1.5-2 cm in diameter and have a green 5 lobed calyx with small appendages on each lobe, 5 yellow heart-shaped petals, and many stamens and pistils. Each pistil has a single slender style attached at or near the top of the ovary.

Phenology
Flowering in late July-early August.

Diagnostic Characteristics
Distinguished from other perennial species of Potentillain Montana by having basal leaves that are strictly trifoliate, and foliage that is sparsely long hairy rather than white wooly beneath.
