Crepis intermedia, commonly known as grey hawksbeard, is a perennial herb in the Asteraceae family. It is native to western North America, including regions such as Alberta, British Columbia, Wyoming, and California. This species was first described in 1884 by A. Gray.

Description

Crepis intermedia is a perennial herb that grows 15-70 cm tall. It features a swollen caudex and one to two flowering stems that are erect, tomentose, and striate. Rosette leaves are elliptic-ovate, pinnatifid, and tomentose, with a petiole-like base. Cauline leaves are similar but fewer in number and apically reduced to scales. The synflorescence is paniculiform or corymbiform, with 10-60 heads. Each head contains 7-16 yellow flowers with ligulate corollas. Involucral bracts are triangular-ovate to narrowly ovate, tomentose, and sometimes hispid. Achenes are cylindrical, 5.5-9.0 mm long, with 10-12 ribs, and a persistent pappus 7.0-10.0 mm long.
