glabrous or densely piloso-puberulent.

glabrous or sparsely to moderately pilose distally or throughout.

basal and proximal cauline 3–5-nerved, linear to narrowly oblanceolate or oblanceolate, 110–220 × 4–10(–12) mm, gradually then abruptly reduced distally (bractlike proximal to heads), essentially glabrous or sparsely pilose to densely piloso-puberulent, weakly gland-dotted (bases of basal usually fibrous-persistent).

basal and proximal cauline 1-nerved, narrowly oblanceolate, 60–170(–200) × 2–7(–11) mm, abruptly to gradually reduced distally (becoming linear, spreading-ascending), essentially glabrous or sparsely pilose (abaxially), gland-dotted (proximal margins piloso-ciliate).

usually 0, rarely (spreading to ascending) 1–2 mm.
