Leaves firm, glabrous beneath, rough above, ciliolate, the lower and basal ones oblanceolate or spatulate, acutish, 3'-6' long, 6"-10" wide, serrate with low distant teeth, narrowed into margined petioles; upper leaves abruptly smaller, linear-oblong or oblanceolate, bract-like, entire, sessile; heads 2"-2i" high, somewhat secund on the spreading, often very slender and elongated branches of the panicle; bracts of the involucre oblong, very obtuse; rays 6-10; achenes puberulent, or glabrous below.
