mouutain would soou deprive them of what little moisture the 

 roots are able to extract from the scant soil. (No. 2327.) 



Erigeron foliosus Nidt. 



Reaches up iuto the piue belt on the south and west sides. 

 (Nos. 2055, 2385.) 



Erigeron Jacinteus Hall, sp. nov. 



Low, two or three inches high, the monocephalous stems 

 ascending or spreading from slender rootstocks, cinereous with 

 a dense but short almost hirsute pubescence: leaves small but 

 exceeding the internodes, spatulate to obovate, obtuse or acute, 

 the larger 3 lines long by 1 line wide, the upper smaller, all 

 sessile by a narrowed base, one-nerved: heads on short peduncles, 

 hemispherical, 7 lines wide including the rays; involucre 2 lines 

 high; bracts narrow, acute, strongly one-nerved, sparsely pubes- 

 cent at least when young, the margins hyaline: rays about 20, 

 2 lines long, purple: akene flattened, strigose pubescent: pappus 

 simple, of merely scabrous awns, equalling the corolla. 



In gravelly soil on the summit of Tahquitz Peak, San Jacinto 

 Mts., California, altitude 8826 ft., June, 1901 (H. M. Hall, 

 no. 2322). The type is in the Herbarium of the University of 

 California. 



The affinities of this species are uncertain. Following the 

 arrangement given in the Synoptical Flora it would seem to 

 belong somewhere near E. c(espitosus, Nutt. if it were not for the 

 broad leaves; in some respects it approaches E. petropJiilus 

 Greene,* lint that and its allies are rayless and have narrower 

 and more elongated leaves than occur in the proposed ppecies; 

 from the members of the E. ursinus group it dififers in having 

 underground stems, in the leafly flowering stems, in the dense, 

 cinereous pubscence, and in other characters. 



Eriophyllum confertiflorum laxiflorum Gray. Golden Yarrow. 

 Conspicuous on all sides of the mountain in the Lower Tran- 

 sition Zone. In the foot-hills it is replaced by typical E. con- 

 fertiflormn. (No. 2519.) 



Eriophyllum Wallace! (iran. 



This species extends up into the pine belt from Chalk Hill 

 where it is common. (No. 2053.)
