 Annual, commonly 2 dm. or less high, much branched from 



the base: herbage floccose-tomentose, glabrate at least below: 

 leaves 2 to 4 cm. long, the expanded upper portion 1 to 2-pin- 

 natifid with oblong lobes, or the uppermost entire : heads short- 

 peduncled, or the earlier on long peduncles : involucre nearly 15 

 mm. high; the loose bracts linear, acuminate but obtuse at the 

 very tip, strongly 1-nerved : corollas flesh-color, much exceeding 

 the involucre, the marginal not appreciably enlarged: anthers 

 included : pappus of 4 oblong-linear paleae only half as long as 

 the corollas and 2 to 4 very short oblong-cuneate outer ones, or 

 these sometimes obsolete. 



Originally known from Nevada and Utah but now collected 

 at the following stations in the Lower Sonoran Zone of the Mo- 

 have Desert: Cushenberry Springs, Parish, no. 1255; Camp 

 Cady, Parish, no. 1256 ; Newberry and Daggett, Hall, nos. 6138, 

 6828; Barstow, Mrs. Brandegee; Keeler, Brandegee. It also 

 comes from Tucson, Arizona, W. F. Parish, no. 122, and is prob- 

 ably widely distributed over the Desert Area, although nowhere 

 very common. Mr. Marcus E. Jones has noted 48 that the flowers 

 are more expanded at night than during the day.
