State Rank Reason (see State Rank above)
Reported for Montana (Dorn 1984). More information needed to determine the status of the species in the state.
Rhizomatous perennials 30-90(-120) cm tall. Stems glabrous or rarely short-hirsute, branching prominently above. Persistent cauline leaves numerous, 4-12(-15) cm long x 2-12 mm wide, linear to elliptic-lanceolate, glandular-punctate (use magnification), 3-nerved or sometimes with 1 or 2 extra pairs of fainter lateral nerves. Inflorescence broad, corymbiform, heads sessile or nearly so in small clusters. Involucre 3-5 mm tall, bracts weakly gluntinous-glandular, obtuse or rounded, yellowish. Receptacle short-fimbrillate. Florets 20-35(40), ray flowers small with the ligule scarcely spreading, more numerous than disk flowers. Achenes short-pubescent (adapted from: Barkley, 1986, Flora of the Great Plains).
Much of North America but much less so in western and southwestern states; most common in northeast and upper midwest (Kartesz in prep. 2012).
