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 and proximal cauline 1-nerved, linear to linear-lanceolate, 70–150 × 1–2.5 mm, abruptly or gradually reduced on distal 1/2 of stems, essentially glabrous (margins sometimes sparsely ciliate).

corolla tubes glabrate inside.

in (2–)3–4(–5) series, broadly obovate (outer) to broadly oblong-obovate, strongly unequal, sparsely strigoso-villous (outer) or essentially glabrous, margins with (pinkish purple) hyaline borders, sometimes slightly erose, usually densely ciliate, apices rounded to subtruncate.
