Characteristics

Plants 25–80(–130) cm). Corms globose. Stems puberulent. Leaves: basal and proximal cauline 1-nerved, usually oblanceolate-to elliptic-spatulate to oblanceolate, 80–290 × 12–25(–45) mm, abruptly, then little or gradually, reduced distally, essentially glabrous or puberulent or hirtellous-hispidulous, weakly, if at all, gland-dotted. Heads in loose to dense, racemiform to spiciform arrays. Peduncles usually 0, sometimes (ascending to spreading or deflexed) 2–8(–30) mm. Involucres turbinate to turbinate-campanulate or campanulate-cylindric, (6–)8–12 × (6–)8–15 mm. Phyllaries in 4–5(–6) series, (usually spreading to distally reflexed, sometimes erect) obovate to oblong-spatulate, unequal, essentially glabrous or puberulent to puberulent-hirtellous, margins sometimes with relatively narrow, weakly differentiated hyaline borders, apices acute to obtuse (at least outer) or rounded (mid and inner). Florets 11–26(–28); corolla tubes pilose inside. Cypselae (3–)3.5–5.5(–6) mm; pappi: lengths ± equaling corollas, bristles barbellate.
More
Similar to no. 1 [Liatris scariosa (L.) Willd.] and evidently hybridizing with it, but avg more robust, to 15 dm, and often more evidently hairy; heads 6–60, often more than 20, commonly in a spiciform infl with the heads turned away from the axis, or the peduncles sometimes more elongate and ascending-spreading, to 5 cm; invol glabrous or often evidently short-hairy, the middle and outer bracts commonly notably loose or squarrose above the middle; fls (11–)14–24(–28) per head. Dry woods and open places, especially in rocky or sandy soil; s. W.Va. and s. O. to s. Mo., s. to Fla. and La. July– Sept. (L. earlei; L. ruthii; L. scabra–the more hairy phase; L. tracyi)
