lower leaves pinnately divided into 5 to 9 narrowly linear revol- 

 ute lobes, the upper with only 3 lobes (the middle one several 

 times larger) , or the uppermost entire : heads in broad terminal 

 open cymes: involucre 8 to 10 mm. high, broadly turbinate; the 

 bracts linear with attenuate tips, dorsally carinate below: rays 

 about 13, the ligules about 10 mrn. long : achenes linear, pubescent. 

 Common throughout Southern California in the Upper Sono? 

 ran Zone, especially in sand-washes and other gravelly places ; 

 north to Lake Co. and east to Nebraska. 8. Blochmanae is ap- 

 parently a form with glabrous herbage and entire leaves. A 

 plant in the botanic gardens at Berkeley has the erect woody stem 

 and the habit of typical 8. Douglasii. Specimens gathered by 

 Miss Eastwood (no. 281) at the type locality have small-sized 

 heads and puberulent herbage. Further collections will prob- 

 ably demonstrate that the two species are not distinct. 



S. MONOENSIS Greene, Leaflets, i. 221 (1906). Near 8. 

 Douglasii but lower, less woody, and the herbage always bright 

 green and glabrous: copiously branched from the short woody 

 portion ; the branches 5 dm. or less high, but often long, flaccid, 

 and decumbent. Near Southern Belle Mine, Mono Co., Heller. 

 no. 8330; among rocks in the Panamint and Argus Mts. and in 

 the Alabama Hills, all in Inyo Co., Hall & Chandler, nos. 6946.

7. S. Lyoni Gray, Syn. Fl. i. pt. 2, 456 (1886). 



Somewhat suffrutescent at base, probably 1 m. or so high, 

 freely branching and leafy throughout: herbage at first tomen- 

 tose, soon glabrate except for persistent dense tufts of wool in the 

 leaf-axils and often a sparse tomentum on the under side of the 

 leaves : leaves once or twice pinnately parted into broadly linear 

 obtuse segments and lobes, sessile by an auriculate base or petiol- 

 ate and the petiole dilated at base: inflorescence loosely cymose. 

 the peduncles bearing a few subulate bracts: involucre broadly 

 turbinate, 7 or 8 mm. high; bracts linear, with acute pubescent 

 tips, the medial line thickened and the margins scarious. 



First collected by N.evin & Lyon on San Clemente Island, ace. 

 to Gray; Santa Catalina Island, May 20, 1890, Brandegee; San 

 Quentin Bay, Lower California, Palmer, no. 644; San Martin 

 Island, Brandegee.
