186 BOTANY OF THE DEATH VALLEY EXPEDITION. 



This species differs from E. baileyi in its smaller size and more diffusely "branching 

 habit, more uniformly green instead of purplish stems, shorter involucres, shorter 

 flowers, and greenish yellow and glabrous, instead of white or pink and slightly 

 glandular, perianth. In all the specimens of E. brachyanthum that I have examined, 

 the stem for a distance of 3 to 10 mm. above the insertion of the leaves is densely 

 and persistently lanate, but above abruptly glabrous. In E. baileyi the stem is at 

 maturity glabrous to the very base. In the field the differences of the two plants in 

 color, size, and habit, are conspicuous. The National Herbarium contains speci- 

 mens collected in the Mohave Desert by Palmer (No. 479 of 1876), Parish Brothers 

 (No. 1359 of 1882), and Tracy, in addition to Nos. 1013 and 1138 of the present collec- 

 tion, the latter from the vicinity of Mohave.

 locality, "Upper California."

Eriogonum incanum Ton. & Gr. Proc. Amer. Acad. viii. 161 (1870). Typo 

 locality, "on the Tuolumne River [Sierra Nevada, California], alt. 8-11,000 feet."

Eriogonum inflatum Torr. & Frem. in Frem. Second Rep. 317 (1845). Type local- 

 ity, "on barren hills in the lower part of North California." 



This species although described as an annual is oftener a barely suffrutcscent 

 perennial. The dead inflated peduncles, remaining throughout the winter and 

 Anally bleaching to a yellowish white color, have given rise to the popular name 

 "cigarette plant." 



It occurs in the Larrea belt throughout the desert, a common and characteristic 

 plant. Specimens were collected in Furnace Creek Cation, Funeral Mountains (No. 

 239), and near Hot Springs, in Panamint Valley (No. 680). 



Eriogonum insigne Wats. Proc. Amer. Acad. xiv. 295(1879). Type locality, "near

 proaching E. incanum in being densely cespitose and in the leaves being canescont-

 marifolium. — W. M. c]
