188 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Eriogoimm polifolium Benth. in DC. Prodr. xiv. 12 (1856). Type Localities, "in 



Sierra Nevada California;" and "ad Sau Diego." 



On Browns Peak (No. 177), and in Cottonwood Canon, Panamint Mountains 

 (No. 966). In this journey from San Bernardino to the Mohave Desert, through 

 Cajon Pass, the loeal geographical limits of this species and E. fasckulatum are clearly 

 brought out. On thesouth or intramontane slope of the pass the latter is an abundant 

 and characteristic plant below the chaparral belt, while on the desert side the lower, 

 broader-leafed E.polifolium, with its elongated peduncles and congested inflorescence, 

 is equally characteristic. It is abundant throughout the upper part of the Lower 

 Sonoran zone in tbo region traversed. 



Eriogonum pusillum Wats. Proc. Amer. Acad. viii. 184 (1870). Type locality 

 "foothills of Trinity Mountains, borders of the Truckee Desert, Nevada." 



Near Willow Creek, Panamint Mountains (No. 770), and near Crystal Spring, Coso 

 Mountains (No. 926). 



Eriogonum reniforme Torr. & Frem. in Frem. Second Rep. 317 (1845). Typo 

 locality, "on the Sacramento river," California. This plant, which has been but 

 sparingly collected, has been found in recent years only in the Mohave Desert region 

 and it is probable that Fremont collected the original specimens there. A similar 

 error in the type locality appears to have been made in the case of Cleomella obtttsi- 

 folia. 



Verified by W. M. Canby. [No. 665 exactly agrees with the type specimen in the 

 Torrey Herbarium. It is a closer set plant than No. 860 and branches from the very 

 base. No. 860 I can not separate from E. reniforme although it appears different. 

 It varies from the type in being of a more open habit— the pedicels longer and more 

 delicate— in its branching just above the base instead of at the very base, in having 

 pedicels in the very lowest axils, and in the whitish glaucous broad turbinate invo- 

 lucres acute at base instead of campanulate and obtuse as in No. 665.— w. M. c] 



Eriogonum saxatile Wats. Proc. Amer. Acad. xii. 267 (1877). Typo localities, 

 "on rocks above San Bernardino," and "in the Santa Lucia Mountains," both in 

 California. 



In Willow Creek Canon, Panamint Mountains (No. 804), and in the valley of the 

 Kaweah River (No. 1329). Determined by W. M. Canby. 



Eriogonum thomasii Torr. Pac. R. Rep. v. pt. ii. 364 (1857). Type locality, 

 "near Fort Yuma," Arizona. 

 Near Hot Springs, Panamint Valley (No. 670). 



Eriogonum trichopes Torr. in Emory, Rep. 150 (1848). Type locality, "eastern 

 slope of the Cordilleras of California." 



Near Hot Springs, Panamint Valley (No. 686), and in the valley of the Virgin 

 River (No 1919). The specific name of thisplant has usually been written trichopodum, 

 but it was published in the form given above. 



Eriogonum umbellatum Torr. Ann. Lye. N. Y ii. 241 (1828). Typo locality, 

 "near the Rocky Mountains." 



In the high Sierra Nevada (Nos. 1451, 1656), and in the Inyo Mountains (No 1786). 

 Determined by W. M. Canby. [No. 1656 is a peculiar, much depressed small-leafed 

 state; the flowers, involucres, and bracts much the same as in Palmer's No. 426 of 

 1877, but the leaves more canesccnt and smaller. — w. m. C] 



Eriogonum virgatum Benth. in DC. Prodr. xiv. 16 (1856). Type locality, "in 



California." 



Near Havilah (No. 1068) and in the valley of the Kaweah River (No. 1317). No. 

 1068 has deep red and No. 1317 yellowish white flowers.
