State Rank Reason (see State Rank above)
Five collections at MONTU, from Beaverhead, Madison, Park counties. Doubtlessly undercollected due to the extremely prickly stems. Not rare at least in Beaverhead County. Grows at high elevations, mostly on talus slopes and other places that are probably secure.
Stems sprawling to ascending, 30–70 cm, spiny at the nodes, bristly between. Twigs puberulent, tan, becoming gray. Leaf blades 1–4 cm wide, cordate, 5-lobed, deeply toothed, pubescent and glandular on both sides. Inflorescence drooping, 3- to 6-flowered. Flowers saucer-shaped, 3–5 mm long, green to pink, glandular-hairy; calyx lobes broadly ovate, 2–3 mm long; petals pink to red, 1–1.5 mm long; stamens longer than petals; style united more than half way, glabrous. Berry 5–9 mm long, red, bristly-glandular, palatable (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
