146 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Arctostaphylos pungens H. B. K. Nov. Gen. & Sp. iii. 278 (1818). Type locality, 

 "in Regno Mexicano, locis alsis, juxta Moran et Villalpaado, alt. 1,300-1,400 hex." 



Collected in the Charleston Mountains, Nevada, near Clark's sawmill (No. 312), 

 among the yellow pities, and at Mountain Springs, in thepifion helt (No. 1879). Dr. 

 Morriam found it on the eastern slope of the Beavcrdam Mountains, Utah. This 

 species of nianzauita, which agrees in all respects with the true A . putigena of Mexico, 

 seems to be confined in the United States to some of the desert mountains east of the 

 Sierra Nevada. If a subsequent collection of data shows this to be true, the distri- 

 bution of the species will correspond with that of many others which extend from 

 the mountains of Mexico northward into the desertand Great Basin mountains of the 

 United States, in a zone higher than that of the true desert vegetation. 



Bryanthus breweri Gray, Proe. Amer. Acad. vii. 367 (1868). Typo localities, 

 " high sierras of California, alt. 10,000 feet; on Wood's Peak, El Dorado Co.; near 

 Donner's Pass; and Mariposa Co.; also Mt. Hoffman." 



Near timber-line in the Sierra Nevada (Nos. 1555, 1829, 2089), 



Kalmia glauca microphylla Hook. Fl. Bor. Amer. ii. 41(1834). Type locality, 

 " swamps in the Rocky Mountains." 



This variety of Kalmia glauca hits a well-defined rangedistinct from that of the type 

 form, yet it is difficult of clear characterization in words. In general it is a lower, 

 smaller plant than the type, with oval leaves, commonly 10 to 15 mm. long, and only 2 

 to 6 llowers in each cluster. It is known to occur on the highest peaks of California, 

 Nevada, Oregon, Colorado, Yellowstone Park, and Idaho. The type form does not 

 occur in this central elevated region, but it extends on the west coast from Alaska 

 south at least as far as Pnget Sound, and on the eastern side of the continent to New 

 England and Pennsylvania. 



Specimens were collected near timber-line in the vicinity of Mineral King (No. 1554). 



Ledum glandulosum Nutt. Trans. Amer. Phil. Soc. new. ser. viii. 270 (1841-43). 

 Type locality, "in the central chain of the Rocky Mountains, on the sides of the 

 mountains which close up Thorn berg's ravine." 



In the high Sierra Nevada (Nos. 1556, 1700). 



Azalea occidentalis Hook. Bot. Mag. lxxxiii. t. 5005 (1857)— Torr. & Gr. MS. 

 Type locality not specifically given. "Our drawing was made from a beautiful 

 specimen sent by the Messrs. Yoitch, " * which was raised from seeds sent 



direct from California by Win. Lobb." The Whipple Survey specimen came from 

 "Laguna de Santa Rosa [California], in low and wet ravines." 



On the western slope of the Sierra Nevada (Nos. 1360, 1841). 



Pyrola picta Smith in Rees, Cycl. xxix. (1819). Type locality, "on the west coast 

 of North America." 

 Sequoia Park (No. 2100). 



Pyrola rotundifolia L. Sp. PI. i. 396 (1753). Type locality, "in Europa septen- 

 torionaliore, Virginia, Brasilia." 



Near Whitney Meadows (No. 1699). Our plant is a large form with thin, orbicular 

 leaves 3 to 6 cm. broad. 



MONOTROPACEiB. 



Pterospora andromedea Nutt. Gen. i. 269 (1818). Typo locality, "in Upper 

 Canada, near the Falls of Niagara." 

 Near Mineral King (No. 1377). 



Sarcodes sanguinea Torr. PI. Frem. 18 (1853). Type locality, "valley of the 

 Sacramento; the precise locality not recorded, but probably on the Yuba River."
