moderately to densely strigoso-hirtellous.

glabrous.

basal and proximal cauline 1-nerved, narrowly oblanceolate to linear-oblanceolate, 90–180 × 2–4(–7) mm, gradually or abruptly reduced distally, essentially glabrous (proximal margins sparsely ciliate).

basal scalelike (usually withering before flowering), cauline 1-nerved, mostly linear, 12–20(–230) × 1.2–3(–4.5) mm, gradually reduced beyond midstem, essentially glabrous (margins ciliate).
