182 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Atriplex torreyi Wilts. Bot. Kins Suvv. 290 (1871), under Obionc; Wats. Proc. 

 Amer. Acad. ix. 119 (1874). Typo locality, "in the dry valleys bordering the 

 Truckee and Carson Rivers," Nevada. 



Atriplex torreyi was found at Resting Springs (No. 200) ; near Twelve Mile Spring, 

 Resting Springs Valley; at Winters's ranch and other points in Palinunp Valley; at 

 Ash Meadows; at several points in Vegas Valley; at the northern end of Owens 

 River: r.ear Walker's ranch, at the southern end of Owens Lake; between Olancha 

 and Littlo Owens Lake; on the east slope of Walker Pass, at 1070 meters; and at 

 Willow Spring, in Antelope Valley. Dr. Merriani found it also in Aniargosa Canon, 

 California ; valleys of the Virgin and Lower Muddy, and Pahranagat Valley, Nevada ; 

 and the Santa Clara Valley, Utah. 



Atriplex tularensis sp. nov. PLATE XIX. 



Annual, monoecious, white scurfy throughout, erect, 20 to 40 cm. high, with a few 

 opposite branches near the base (or simple), strict, the ends of the stem and branches 

 inclined to be flexuous; lower leaves 1.5 to 2 cm. long, lanceolate, acuminate, taper- 

 ing to an almost sessile base, 3- to 5-nerved, often with minute leaves fasciculate in 

 their axils; upper leaves smaller, passing into the bracts of the inflorescence; flowers 

 in small glomerules sessile in the axils of the leaves and passing above into a long, 

 bracteate, interrupted spike, those of both sexes growing in the same glomeruli ; bracts 

 similar to the leaves, but ovate, acute, and only 2 to 5 mm. long, calyx of male dowers 

 4-partod, a little less than 1 mm. long; fruit 3 to 3.5 mm. long, rhombic-ovate, usu- 

 ally acuminate, with 1 to 3 teeth on either margin above the middle, closely white- 

 scurfy, the valves connate to the middle; seed 1 mm. in diameter. 



Type specimen in the United States National Herbarium, No. 1235, Death Valley 

 Expedition; collected July 13, 1801, on the Tulare Plains of California, about 25kilo- 

 meters south of Bakersfield, by Frederick V. Coville. 



The long, erect, slender, leafy branches of this species give it a characteristic and 

 graceful appearance. 



Grayia spinosa (Hook.) Fl. Bor. Amer. ii. 127(1838), under Chenopodhint; Moq. 

 in DC. Prodr. xiii. pt. ii. 119 (1849). Type locality, " interior of North California." 



This shrub was found near Hcsperia (No. 47) ; on tin; first divide north of Daggett ; 

 on Browns Peak; on Lone Willow Peak, from 790 meters to the summit; on the 

 mountain slopes east of Resting Springs; on the divide between Resting Springs 

 andPahrump valleys; on the eastern and western slopes of the Charleston Mountains, 

 beginning at about 1,000 meters; in the Funeral Mountains, west of Amargosa, from 

 975 meters to the summit; on the divide between Towner's and Ash Meadows; at 

 many points in the Panamint Mountains (No. 015); near the summit station on 

 the road from Mohave to Searles's; near Crystal Springs, in the Coso Mountains; 

 between Lone Pine and Olancha; on the eastern slope of Walker Pass; near the 

 mouth of Tehachapi Canon; and in Antelope Valley. Dr. Merriam reported it in 

 Deep Spring Valley, California; in Fish Lake Valley, between Gold Mountain and 

 Mount Magrnder, Sarcobatus Flat, Oasis, Timpahute, Pahranagat, Desert, and 

 Meadow Creek valleys, and Pahroc Plaiu, Nevada; and in the Boaverdam Moun- 

 tains and Santa Clara Valley, Utah. The shrub is characteristic of that portion 

 of the Lower Sonoran zone which lies above the upper limit of Larrea, yet it often 

 extends down into the Larrea, sometimes to the altitude of 800 or 1,000 meters. 



Eurotia lanata (Pursh) Fl. ii. 602 (1814), under Diotis; Moq. Enum. Chenopod. 

 81 (1810). Type locality, "on the banks of the Missouri, in open prairies." 



We first met with this plant on Browns Peak (No. 171) at, an altitude of about 

 1,300 meters, iu the upper part of the Larrea belt. On Lone Willow Peak single plants 

 in sheltered localities were seen at 1,000 meters, but it was not abundant below 1,340 

 meters. It was recorded afterward on both slopes and the summit of the divide between 

 Resting Springs Valley and Pahrump Valley; on the eastern and western foot-
