Treatment appears in FNA Volume 20. Treatment on page 401. Mentioned on page 398, 399.

Annuals or biennials, rarely short-lived perennials. Stems usually 1 (sometimes more), erect, glabrous, puberulent, or canescent, sometimes sparsely stipitate-glandular; branches ascending. Mid leaf-blades lanceolate to linear. Peduncles equaling or longer than involucres. Involucres campanulate to broadly turbinate, 6–10 (–12) mm. Phyllaries in 4–8 series, usually appressed, sometimes spreading, rarely reflexed; apices usually glabrous or moderately stipitate-glandular, rarely canescent. Ray-florets pistillate, fertile. Cypselae sparsely appressed-hairy.


Phenology: Flowering Jul–Sep.
Habitat: Grasslands, creosote bush scrublands, pinyon-juniper woodlands, pine forests
Elevation: 1000–2300 m
