Vol.1] Hall. — Botanical Stirvey of San Jacinfo Mountain. 73 



Considerable time was speut in tracing the limits of the 

 range of this local species, the type locality of which is Straw- 

 berry Valley. It was fonnd to be quite plentiful on gravelly 

 benches in the open pine forests of the south and west sides from the 

 lower edge of the pine belt to 8200 ft. alt., where it was collected 

 on Mistake Creek and near Tahquitz Peak. It is most common 

 on Fullers Ridge from which it reaches to Snow Creek. It 

 occurs only sparingly in Tahquitz Valley but extends down into 

 the upper part of the chaparral belt of the east side, where it is 

 more plentiful. A robust form was collected in 1898 by Dr. 

 C. A. Purpus on Cuyamaca Mt., the only known station outside 

 of the San Jacinto Mts. Its zonal position is Transition, rarely 

 running over the lower border. (Nos. 849, 2364, 2431, 2564.) 



The specimens vary from a few inches to 2 ft. or more in 

 height. The following field notes were taken on no. 2431, from 

 the upper part of the chaparral belt of the east side: Obtuse 

 lobes of the involucre equalling the tube, fully equalled by the 

 stipe; outer perianth segments merely obtuse and long-apiculate, 

 inner segments with a truncate tip which is horned from the 

 sides and apiculate from the emarginate center; the red anthers 

 pendulous when j'oung, not exserted. 



Eriogonum Baileyi Wats. 



Collected on Chalk Hill and near Fuller's mill. (No. 2988.) 



Eriogonum fasciculatum Benth. Wild Buckwheat. 



Very common throughout the Upper Sonoran Zone and occa- 

 sionally found beneath the pines. (No. 764.) 



Eriogonum gracile Benth. 



On the south side with the next. (Nos. 860, 2624.) 



Eriogonum molestum H7//.s'., Proc. Am. Acad, xvii, 379 (1882). 



Common on the south and west sides at 5000-6000 ft. alt. 

 In sandy, open places around Strawberry Valley are found large 

 Eriogonum beds composed of this species intermixed with E. 

 gracile, from which it may be distinguished by its taller, always 

 glabrous branches, its leaves which are more obtuse at base, its 

 long internodes (an inch or more), and larger involucres and 

 flowers. (Nos. 2386, 2624a.)
