Treatment appears in FNA Volume 20. Treatment on page 429. Mentioned on page 426.

Perennials (perhaps flowering first or second-year), 30–50 (–150) cm. Stems erect, stramineous to pinkish, usually villosulous to hirtellous and/or stipitate-glandular, sometimes glabrate. Cauline leaf-blades mostly ovate to oblong, (7–) 15–30 (–55) mm, lengths 2–4 times widths, bases ± clasping, margins crenate (teeth mostly 3–5 per cm, blunt, resin-tipped), apices obtuse to acute, faces usually hirtellous and little, if at all, gland-dotted, sometimes glabrate (then gland-dotted). Heads borne singly or in open to crowded, corymbiform arrays. Involucres broadly urceolate to globose, 8–13 × 12–22 mm (often subtended by leaflike bracts). Phyllaries in 5–6 series, reflexed to spreading, linear to lanceolate, apices subulate to terete, ± recurved to straight (terminal setae incurved), moderately to strongly resinous. Ray-florets 18–25; laminae 8–11 mm. Cypselae stramineous to light-brown, (2–) 3–3.5 mm, apices smooth to minutely coronate, faces smooth or striate (angles ± ribbed); pappi of 2 ± straight, usually smooth (apices usually dilated), setiform awns 4–7 mm, ± equaling disc corollas. 2n = 12.


Phenology: Flowering Jun–Sep(–Oct).
Habitat: Open sites, rocky slopes of limestone, dry gravelly washes, alluvium
Elevation: 1100–2000 m
