retrorsely hairy or puberulent, sometimes glandular-pubescent distally or glabrescent, not glaucous.

24–75(–98) cm, sparsely to densely retrorsely hairy or puberulent, usually also glandular-pubescent distally.

basal and cauline, basal usually absent at anthesis, opposite, leathery or not, glabrous, puberulent, or retrorsely hairy, not glaucous;

basal and proximal cauline petiolate, sometimes short-petiolate or sessile (P. dasyphyllus);

cauline sessile, sometimes short-petiolate (P. lanceolatus), blade lanceolate or linear, margins entire.

retrorsely hairy;

basal and proximal cauline 8–80 × 3–12 mm, blade lanceolate or spatulate, base tapered, margins entire, apex rounded to obtuse or acute;

cauline 7–15 pairs, 9–85(–110) × 1–11(–22) mm, blade lanceolate to linear, base tapered to truncate, apex acute to acuminate, rarely obtuse.

interrupted, ± secund to cylindric, axis glandular-pubescent or glabrous, cymes 1 or 2 per node;

peduncles and pedicels ascending to erect.
