proximally clothed with marcescent leaves, usually glabrous, sometimes sparsely scabrous, usually viscid, sometimes eglandular.

basal; narrowly petiolate;

blades, 1- or 3-nerved, linear to narrowly oblanceolate or spatulate, 17–90 × 1–7(–12) mm, rigid, attenuate, margins sometimes ciliate (often minutely), viscid-glandular veins conspicuously raised abaxially, apices acute, faces ± scabrous or glabrous, gland-dotted, viscid.

20–155 mm, usually lanate at least immediately proximal to heads, sometimes stipitate-glandular.

30–45(–57);

corollas funnelform to narrowly vase-shaped, 5.5–8.5 mm, tubes sparsely hairy, lobes 0.7–1.4 mm, ca. 1/8–1/6 length of corollas;

anthers 2.5–3 mm, style-branch appendages subulate to broadly lanceolate, 0.6–1.4 × 0.7 mm, stigmatic lines 0.6–1.8 mm, lengths nearly 2 times appendages.

21–39;

corollas funnelform to vase-shaped, 4–9 mm, tubes glabrous or rarely sparsely hairy, lobes 0.7–1.3 mm, ca. 1/8–1/6 length of corollas;

anthers 1.8–3.5 mm, style-branch appendages subulate to lanceolate, 1.2–2.3 × 0.5 mm, stigmatic lines 0.6–1.9 mm, 1/2–3/4 as long as style-branch appendages.
