CATALOGUE OF SPECIES. 179 



ILLECEBRACE.E. 



Achyronychia cooperi Torr. & Gr. in Gray, Proc. Amor. Acad. vii. 331 (1808). 

 Type locality, "in dry Hand, Mohave River, at Camp Cady," California. 



Between Bennett Wells and the Eagle Borax Works, Death Valley (No. 288) ; north 

 of the latter place (No. 473); and in Hall Canon at the western base of the Pana- 

 mint Mountains. All these localities are in very hot and arid portions of the Lower 

 Sonoran zone. 



AMARANTACEiE. 



Amarantus albus L. Sp. PI. ed. 2. ii. 1404 (1762). Type locality, "in Philadelphia? 



maritiniis." 



An Amarantus identified in the field as A. albus was found at a few points in the 

 desert: Ash Meadows, Nevada; Corn Creek, Vegas Valley, Nevada; Johnson Canon, 

 Pananiiiit Mountains; and frequently along our route in the southern Sierra Nevada 

 between Walker and Tehachapi passes. In all these places it occurred as a weed in 

 cultivated soil or in moist areas about camping places. The ordinary soil of the desert 

 was altogether too arid for it. 



Cladothrix oblongifolia Wats. Proc. Amer. Acad. xvii. 376(1882). Type local- 

 ities, "on the banks of the Colorado, near Chimney Peak," "at Yuma," and "in 

 the Mohave Desert." 



This plant has been considered an annual, like C. lanuginosa, but the base of the 

 stem often persists for several years. In one of our specimens this woody trunk has 

 a diameter of 12 mm, and shows five well-defined annular layers. It is to be noted, 

 therefore, that this species closely resembles C, suffniticosa, which is known only 

 from imperfect specimens collected by Charles Wright in 1849 in the valley of the 

 Rio Grande. 



The species occurred on the washes and gravel slopes of Death Valley (No. 194), 

 from Furnace Creek to Saratoga Springs; at several points in Resting Springs 

 Valley; at Ash Meadows; in the Vegas Wash ; and in Hall and Surprise canons, 

 Panamint Mountains. The plant is characteristic of the lower altitudes of the 

 Larrea belt. 



CHENOPODIACE-SJ. 



Monolepis spathulata Gray, Proc. Amer. Acad. vii. 389 (18G8). Typo locality, 

 "Sierra Nevada, at Mono Pass," California. 

 Willow Creek Canon, Panamint Mountains (No. 812). 



Chenopodium album L. Sp. PI. i. 219 (1753). Type locality European. 

 No. 813, collected with the preceding. 



Chenopodium californicum Wats. Proc. Amer. Acad. ix. 101 (1874), under 

 Blitum; Wats. Bot. Cal. ii. 48 (1880). Type locality, "California, from the Sac- 

 ramento to Fort Tejon and San Diego." 



This was seen only in the southern Sierra Nevada at several points along our 

 route between Kernville and Tehachapi, growing in, or somewhat below, the 

 chaparral belt. Specimens were collected between Kernville and Havilah (No, 

 1059). 



Chenopodium fremonti Wats. Bot. King Surv. 287 (1871). Type locality, as 

 taken from Fremont's specimen, "on the North Platte. " 

 In Willow Creek Canon, Panamint Mountains (No. 815).
