Rydberg: Species from Western United States 545 



Symphoricarpus Parishii 



Apparently rather tall shrub for the group ; bark of the old 

 stems gray, of the young twigs brown ; leaves of older stems 

 small, about 1.5 cm. long, narrowly oval, acutish at both ends, 

 densely pubescent, more or less bluish green, rather thick ; those 

 of the young shoots larger, about 3 cm. long, deeply 3-lobed and 

 coarsely toothed ; corolla elongated campanulatc, 6-'j mm. long. 



This resembles mostly 5. rotundifoluis in pubescence and flow- 

 ers, but is evidently a larger plant and the leaves are bluish green 

 and acutish at both ends. It seems to be confined to Southern 



California.

Erigeron flabellifolius 



Perennial with a long slender creeping roctstock ; stem 



1-2 



dm high, few-leaved, glandular pubcrulent above ; basal leaves 

 petiolcd, about 3 cm. long, slightly glandular pi.bcrulent, cuneate- 

 flabelliform in outline, deeply 3-5 -cleft into cuneate 3-lobed divis- 

 ions or the lower simply 5-9-lobed at the r.pex ; stem-leaves 

 cuneate or obovate, smaller, subsesslle and less divided; heads 

 about 10 mm. high and 10-15 mm. in diameter; bracts linear, 

 acuminate, with more or less spreading tips, dark brown or purplish 

 black, glandular puberulent ; rays 7-8 mm. long and 1. 5-2 mm. 

 wide, light pink or white. 



This is a member of the E. compositmn group, easily distinguished 

 from its relatives by the form of the leaves, which are never com- 

 pound, but simply cleft two thirds their length or less. It is also 

 characterized by the lack of hirsute pubescence generally found in 

 that group. It grows In rocky slides at an altitude of 3600 m.
