Leaves: basal cauline nearly always withering well before flowering, linear-oblanceolate, smaller than proximal mid cauline, serrate; proximal persisting, sometimes brown-black after senescence, often twisted; proximal to distal numerous (100+ on tall stems) , crowded, sessile, blades (bright green) linear to linear-lanceolate, 20-70 × 2-7(-10) mm, margins remotely serrulate (proximal) to entire or with 1-2 minute serrations (distal), obscurely 3-nerved, one or both faces glabrous or finely strigillose. Heads 100-300+, in short to elongate, pyramidal paniculiform arrays, branches recurved, secund. Peduncles 1-4 mm, finely strigilloso-villous; bracteoles 0-2, linear, grading into phyllaries. Involucres narrowly campanulate, 2.5-3.5 mm. Phyllaries in 3-4 series, strongly unequal; outer ovate, acute, inner oblong, obtuse to rounded. Ray florets 2-8; laminae 1-2 × 0.25-0.5 mm. Disc florets 2-4(-6); corollas 2.3-3.5 mm, lobes 0.4-1 mm. Cypselae (narrowly obconic) 1 mm, strigillose; pappi 2-3 mm. 2n = 18. Flowering Aug-Nov (year-round).
