Stems 15–25 cm, glabrous to stipitate-glandular. Leaves: basal blades mostly erect, filiform, (2–) 3–8 cm × 0.3–0.7 mm, herbaceous. Inflorescences subcapitate, subcongested to proliferating cymes; bracts scattered within inflorescence. Pedicels 1–6 (–15) mm, glabrous or sometimes stipitate-glandular. Sepals weakly to conspicuously 1–3-veined, (4.5–) 5–6 mm, apex acute to acuminate or spinose, glabrous or glandular.


Phenology: Flowering late spring–summer.
Habitat: Sagebrush plains and slopes
Elevation: 500-900 m

Discussion

We consider var. glandulifera to be a glandular extreme of var. prolifera. It is known from a single specimen (Ownbey & Ownbey 2763, NY) collected in Valley County, Idaho, in 1946. While most specimens of var. prolifera are glabrous, the pubescence on the stems and pedicels of a collection from Douglas County, Washington (Hitchcock 17459, WTU) closely approaches that seen on the type of var. glandulifera.
