Short-leaved Cinquefoil - Potentilla brevifolia
State Rank Reason (see State Rank above)
Rare in Montana, where it is currently only from a few collections from the Madison Range. 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.
Perennial from a long-branched rootstock, clothed in old leaves. Stems ascending, glandular, 5–15 cm. Leaf blades cordate-ovate, 10–15 mm long, pinnately divided into 3 to 7 deeply lobed, fan-shaped, glandular-puberulent leaflets. Inflorescence a several-flowered, glandular cyme with ascending branches. Flowers: sepals ovate, 3–4 mm long with shorter, lanceolate bracteoles; petals yellow, 5–6 mm long, retuse. Achenes smooth, 1–1.5 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Flowering in August.
Distinguished from other Montana Potentilla by combining perennial mat-forming habit, finely glandular-hairy herbage, short pinnate leaf blades, and a style attached between the middle and top of the ovary.
