sericeous proximally, glabrous or glabrate distally, stipitate-glandular throughout.

basal overwintering, in rosettes (at ends of short rhizomes), ascending to spreading, blades linear-oblanceolate, 50–250(–350) × 5–10 mm, margins sometimes stipitate-glandular, apices acute, faces sparsely to densely silky-sericeous;

cauline ascending, linear, greatly reduced distally, margins sparsely to densely stipitate-glandular, sparsely sericeous, glabrescent, or densely stipitate-glandular;
