Plants 60-120 cm; caudices short, stout. Stems 1-5+, erect to arching, puberulent in arrays and in lines proximal to leaf bases or uniformly. Leaves usually anise-scented when crushed ; basal and proximal usually withering by flowering, tapering to broadly winged petioles, blades oblanceolate, margins entire, short-strigillose, faces glabrous or short scabroso-strigillose along main nerves; mid and distal cauline sessile, blades lanceolate to linear-lanceolate or narrowly ovate, 30-110 × 8-20 mm, much reduced distally, bases rounded, margins entire, midnerves prominent, sometimes scabroso-strigillose basally to much of length, apices acute, faces glabrous, finely translucent gland-dotted. Heads (20-)75-350, in paniculiform arrays, openly secund, pyramidal, proximal to mid branches ascending to spreading, recurved, secund, 3-18 cm. Peduncles thin, 2-8 mm, glabrate to finely puberulent, glabrous strips proximal to few linear-lanceolate bracteoles. Involucres narrowly campanulate, 3.5-5 mm. Phyllaries in 3-4 series, strongly unequal, yellowish, acute, glabrous; outer narrowly ovate to lanceolate, inner lanceolate to linear-lanceolate. Ray florets 3-4(-6); laminae 1.4-2.5 × 0.4-0.9 mm. Disc florets 3-5; corollas 2.7-3.5 mm, lobes 0.5-1.3 mm. Cypselae (obconic) 1.4-2.3 mm, strigose to glabrate; pappi 2.4-3 mm.
