78 NORTH AMERICAN FLORA [Volume 34 



strigulose; leaves linear to filiform, entire, acute; peduncles 1-15 cm. long; involucre broadly 

 hemispheric, 3-6 mm. high, its 10-18 bracts oblong-ovate and acute; receptacle acutely conic, 

 muricate; ray-flowers as many as the bracts (both bracts and ray-flowers few in number in 

 depauperate plants); ligules 4-8 mm. long, often distinctly paler on the upper half; achenes 

 linear-clavate and with slightly rounded summit in the typical form, either perfectly smooth 

 and shining or with minute rounded papillae; pappus none in the typical form. (In var. 

 gracilis and its forms the achenes are truncate at summit, more or less strigose-pubescent, and 

 usually but not always bear a pappus of 2-5 awns or squamellae of varying shape.) 



Type locality: Vicinity of Bodega Bay, California. 



Distribution: Southern Oregon to Lower California, east to Arizona; abundant on the plains 

 and lower foothills in California.

Annual with thick but weak branching stems 0.5-2 dm. high, strigose and also short- 

 hirsute; leaves broadly linear to oblong-spatulate, entire or dentate, obtuse; peduncles 1-6 cm.

 7-10 mm. long; achenes linear-clavate, not rounded at the summit, somewhat angled, smooth 

 or usually conspicuously papillate but not strigose; pappus of 2-4 slender bristles slightly 

 widened at the base, or entirely wanting.

Annual, erect, usually with several purplish wiry branches from the base, about 1.5 dm. 



high, glabrous except for some fine deciduous woolliness, the foliage and involucre slightly 



succulent; leaves all entire and narrowly linear, or some irregularly pinnatifid into nearly 



filiform segments; peduncles 1-6 cm. long; involucre campanulate, 6-7 mm. high, the 7-9 



bracts elliptic or oblong-lanceolate and acute, each bract 3-nerved at base, the middle nerve 



carinately thickened; receptacle narrowly conic, acute, strongly muricate; ray-flowers 7-9 



or perhaps more numerous, the elliptic ligules about 8 mm. long; disk-corollas glabrous or 



only granular; achenes slenderly clavate, angled, scabrous or strigose with upwardly pointing 



hairs; pappus of 4-7 ovate squamellae each tapering to a slender awn, or wanting.
