Treatment appears in FNA Volume 20. Treatment on page 399.

Annuals, biennials, or short-lived perennials. Stems usually 1, stiffly erect, canescent, sometimes sparsely stipitate-glandular; branches widely divaricate, straight, stiff. Mid leaf-blades linear-lanceolate to linear. Peduncles equaling or longer than involucres. Involucres broadly turbinate, 6–10 (–12) mm. Phyllaries in 5–10 series, usually reflexed, apices usually canescent, stipitate-glandular. Ray-florets pistillate, fertile. Cypselae sparsely to moderately appressed-hairy.


Phenology: Flowering Jun–Oct.
Habitat: Grasslands, sagebrush scrublands, usually in sandy or alluvial soils along streams
Elevation: 300–1500 m
