MNPS Threat Rank
State Rank Reason (see State Rank above)
Numerous collections at MONTU from Teton, Madison, Granite, Gallatin, BigHorn, Carbon, Powell and Lewis & Clark counties. Many of the collections are recent. This species may be eventually displaced by nonnative invasives. Should be watched over time.
Stems ascending, 15–50 cm. Herbage tomentose. Basal leaf blades lanceolate, 5–25 cm long, pinnately divided into numerous entire to shallowly lobed, lanceolate to ovate segments. Involucre hemispheric, 12–25 mm high; phyllaries lanceolate, tomentose, outer shorter than the inner. Ray ligules 25–35 mm long. Disk corollas 6–9 mm long, lobes hairy to glandular (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Not likely to be confused with any other species in Montana, except perhaps Balsamorhiza hookeri, which differs in having pinnately lobed leaves, and harsh and short pubescence, rather than the soft, tangled hairs of B. incana.
