Eremiastrum bellioides Gray, PI. Thurb. 321 (1854). Type locality, "on the 

 Californian desert, not far west of the Colorado." 



Near Saratoga Springs (No. 254). This plant is not typical E. bellioides, but an 

 intergrade between it and E. bellioides oreuttii, nearer, however, tho former. 



Eremiastrum bellioides oreuttii (Wats.) Troc. Amor. Acad. xxv. 132 (1890), as 

 E. oreuttii. Type locality, "in the southeastern part of tho Colorado desert, in San 

 Diego County, California." 



This species of Eremiastrum was originally described thus: "Pappus consisting of 

 five, white oblong-ovate laciuiate pale* and as many inner alternate bristles twice as 

 long; in every other respect — habit, foliage pubescence, involucre, etc. — the nearly 

 exact counterpart of Ft. bellioides. From its close resemblance to E. bellioides it 

 might be supposed to be a variety of that species, but no intermediate forms are 

 detected among previous collections." From the specimens now collected it is evi- 

 dent that, while the pappus bristles in this plant are commonly 5, they vary from 1 

 to 8, the paleas meanwhile remaining comparatively constant. No. 440 is largely typ- 

 ical. In some specimens, commonly the more robust ones, the palese are longer and 

 laciniately parted, while at the same time both they and the bristles are more than 

 5 in number. In short, a complete intergradation exists between the two plants. 

 Nos. 326 and 674 are such intermediate forms. The geographic relationship of the 

 two plants is not well determined, but specimens from Arizona usually belong to the 

 type, while those from the Mohave and Colorado deserts, in California, are offcener 

 of the variety. Monoptilon bellidiforme, which can he distinguished from Eremiastrum 

 only by its pappus, is undoubtedly a derivative of the same group. 



Our specimens were collected in the Funeral Mountains (Nos. 326, 440) and in 

 Panamint Valley (No. 674). 



Aster andersonii Gray, Proc. Amer. Acad. vi. 510 (1865), under Erigeron; Gray, 

 Proc. Amer. Acad. vii. 352 (1868). Type localities, " Novada, near Carson City," and 

 "Lake Tenaya, in the Sierra Nevada." 



In the high Sierra Nevada (Nos. 1565, 2114). No. 2114 was collected in a meadow 

 closely grazed by cattle, and it has the short spreading leaves and assurgent stems, 

 but not the villous achenia, commonly characteristic of A. pulchellus. 



Aster canescens tephrodes Gray, Syn. Fl. i. pt. ii. 206 (1884). Typo localities, 

 "California, Arizona, and New Mexico." 

 Near St. Thomas, Nevada (No. 1929). 



Aster canescens viscosus (Nutt.) Trans. Amer. Phil. Sot;, new ser. vii. 301 

 (1841), as Dieteria viscosa; Gray, Syn. Fl. i. pt. ii. 206 (1884). Type locality, "near 

 Scott's Bluff, on the Platte." 



At Soda Springs, Sierra Nevada (No. 1605). 



Aster carnosus Gray, PL Wright, ii. 80 (1853), under Linosyris; Gray, Syn. 

 Fl. i. pt. ii. 202 (1884). Type locality, "low, subsaline valley west of the Chiriea- 

 hui Mountains, Sonora," Mexico. 



This peculiar desert aster was abundant at Resting Springs, Nevada, in tho alka- 

 line salt grass meadows (No. 270), and was found also at Ash Meadows and about 

 a soda-flat on the road between the latter point and Townees ranch. All these lo- 

 calities are in the valley of the Amargosa River. 



Aster integrifolius Nutt. Trans. Amer. Phil. Soc. new ser. vii. 291 (1841). "An 

 alpine species growing with the above [A. andinus"], but at a lower elevation." The 

 type locality of A. andinus is " on the highest summits of the Rocky Mountains, near 

 the line of perpetual snow, in 42°." 



Near Farewell Gap, Sierra Nevada (No. 1742).
