Leaves: basal and lower cauline 3–5-nerved, narrowly oblong-lanceolate to narrowly spatulate-oblanceolate, 60–180(–330) × 6–12(–15) mm (usually becoming more densely arranged distally), abruptly reduced near midstem (continuing densely to immediately proximal to heads), essentially glabrous, gland-dotted (bases of basal often fibrous-persistent). Heads in dense, spiciform arrays. Peduncles 0. Involucres turbinate-cylindric to turbinate-campanulate, 7–9 × 4–7 mm.
