Stems | villous to lanate, eglandular or densely stipitate-glandular. |
||||
Leaves | basal; petioles slender; blades 3-nerved, linear to narrowly oblanceolate or spatulate, 24–70(–100) × 1.5–9 mm, pliable (abaxial faces ± plane), bases attenuate, margins eciliate, eglandular, apices acute to obtuse, faces villous to lanate (trichomes multicellular), or glabrous adaxially, and/or stipitate-glandular. |
||||
Peduncles | 20–155 mm, usually lanate at least immediately proximal to heads, sometimes stipitate-glandular. |
||||
Involucres | broadly campanulate to hemispheric, 13–28 × 9–15 mm. |
||||
Ray florets | 9–17; laminae elliptic, 8–14 × 2.5–7 mm. |
||||
Disc florets | 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. |
||||
Phyllaries | 18–37(–64) in 2–3 series, 1- or 3-nerved, scarcely unequal, outer lanceolate to narrowly oblong, 7.5–11.5 × 1–3 mm, mid and inner lanceolate, 8–12.5 × 1–4 mm, proximally rather indurate, distally herbaceous and pliable, margins scarious, sometimes broadly so, often fimbriate, wholly green except for margins or with narrow green portions longer than broad, apices acute to acuminate, abaxial faces villous and/or stipitate-glandular. |
||||
Heads | borne singly. |
||||
Cypselae | 2.5–5(–6.5) mm, lengths 2/3 disc corollas, faces thinly sericeous; pappus bristles 40–50, 5–9.5 mm, nearly equaling to slightly longer than disc corollas. |
