CATALOGUE OF SPECIES. 121 



Chrysopsis breweri Gray, Proc. Amer. Acad. vi. 542 (1865). Type locality, 

 "near Sonora Pass and Ebbett's Pass, in the Sierra Nevada, common at the elevation 

 of 4,000 to 8,000 feet." 



Between Mineral King and Farewell Gap (No. 1485). 



Aplopappus apaigioides Gray, Proc. Amer. Acad, vii.354 (1868). Type locality, 

 "at Soda Springs, on the Tuolumne River [California], alt. 9,700 feet." 

 In the high Sierra Nevada (Nos. 1608, 2133). 



Aplopappus blooraeri Gray, Proc. Amer. Acad. vi. 541 (1865). Type locality, 

 "on Mount Davidson, Nevada." 

 Near Soda Springs, Sierra Nevada (Nos. 1600, 1728). 



Aplopappus cuneatus Gray, Proc. Amor. Acad. viii. 635 (1873). Type locality, 

 "California, in 'Bear Valley, alt. 4,500 feet.'" 



In our specimens, as well as in others collected in the Colorado Desert by C. R. 

 Orcutt, the leaf-blades are commonly 12 mm. and sometimes 20 mm. long, while in 

 most localities they reach only 4 to 8 mm. The singular distribution of the species 

 leads one to suspect that it may include more than one species or variety. 



It was seen in but few localities: on the east slope of the Slate Range, west of 

 Lone Willow Spring (No. 185); on the east slope of the Panamint Mountains, near 

 the head of Johnson Canon, growing on exposed rocks in the pinon belt; and in 

 Surprise Canon, near Brewery Spring (No. 599). In all these localities it grew not 

 far either above or below the line between the Upper and Lower Sonoran. Its 

 habitat was always the clefts of rocks, usually in canons. 



Aplopappus interidr Coville, Proc. Biol. Soc. Wash. vii.-65 (1892). Type lo- 

 cality as given below. 



" Related to A. Unearifolim DC, but differing in its shorter leaves (12 to 20 mm.), 

 subulate-bracteate peduncle, shorter, acute, involucral bracts, aud smaller rays 9 to 

 11 mm. long. In A. linearifolius the larger leaves are 30 to 40 mm. long, the pedun- 

 cles leafy-bracted, the involucral bracts 11 to 14 mm. long, including the filiform- 

 subulate acumination, and the rays 13 to 15 mm. long. 



"Type specimen in the United States National Herbarium, No. 794, Death Valley 

 Expedition; collected May 20, 1891, about 4 miles southeast from Mill Canon Divide, 

 at the northern edge of the Darwin Mesa, Inyo County, California, by Frederick V. 

 Coville. 



"A. Unearifolim, first collected in California by Douglas, probably near San Fran- 

 cisco or Monterey, is known only from the coast ranges southward from San Francisco 

 Bay. A. interior is a species of the desert mountains, and has been collected in the 

 higher elovations of the Lower Sonoran region from southern Utah, northwestern 

 Arizona, and Inyo County, California, southward to the extra-coastal region of San 

 Diego County." 



This shrub was seen in flower in Johnson (No. 503), Mill Creek (No. 794), and 

 Willow Creek canons, Panamint Mountains; aud at Crystal Spring, Coso Mountains 

 (918), growing in the Upper Sonoran zone, below the pinon belt. It was seen in 

 Tehachapi Canon from about a mile west of Cameron to its eastern end, between the 

 Larrea and pinon belts; and at several points between Walker Pass and Caliente. 

 It probably occurred frequently at this altitude in other parts of the desert, but in 

 its winter condition it was not distinguished from other similar shrubs. 



Aplopappus monactis Gray, Proc. Amer. Acad. xix. 1 (1883). Type locality, 

 "borders of the Mohave Desert, S. E. California." 



Specimens were collected near Hesperia (Nos. 48, 53) ; in Mill Creek Canon, Pana- 

 mint Mountains (No. 802) ; near Lone Pine (No. 893) ; in the Canada de las Uvas (No. 

 1144) ; and in Sarcobatus Flat, Nevada (No. 2002). The species is characteristic of 

 the upper altitudes of the Lower Sonoran zone, and is probably an abundant plant 

 in many other localities of the Mohave Desert region.
