having searched for it in vain, and having come to regard it as 
extinct, or wrongly attributed to their region. JOHNSTON’s station 
and BREWER’S are not widely separated. 
Yucca BAccata Torr. Bot. Mex. Bound. Surv. 221. 1856.—Abun- 
dant on mesas and foothill slopes of New York (Barnwell, 10281, 
June 4, 1915), Ivanpah, and Providence mountains, in the south- 
eastern part of the Mojave Desert. Associated with Y. brevifolia 
Engelm. and Y. mohavensis Sargent. From the last species, the 
acaulescent forms of which it much resembles, it can readily be 
distinguished by the yellow-green color of the foliage. The plants 
are acaulescent, or nearly so, in few-branched clumps, the close 
panicle elevated on a scape not more than a meter high. 
PHYLLOGONUM LUTEOLUM Coville, Contr. U.S. Nat. Herb. 4: 
190. pl. 21. 1893.—Furnace Creek, Death Valley (10008, May 18, 
1915). Very sparingly scattered among the pebbles covering the 
dry bed of the stream, immediately above the small marsh from 
which the stream rises, probably the exact spot where CovILLE, on 
April 7, 1891, collected the two specimens on which he founded the 
genus, since which time the plant had not been rediscovered. ‘Two 
small specimens were also seen in a dry wash between Furnace 
Creek and Saratoga Springs. So far as known, the species is an 
endemic of Death Valley, and very rare even there. The plants 
are prostrate, and the largest found had stems hardly 3 cm. long. 
ATRIPLEX CONFERTIFOLIA Wats. Proc. Amer. Acad. 9:119- 
1874.—This is one of the most widely distributed plants of the 
Mojave Desert, and often the dominant species, but it has not 
been found in the Colorado Desert, where A. canescens James 
occupies a like dominance. The latter species is found in most 
parts of the Mojave Desert, but constitutes a very subordinate 
part of the plant cover. 
* SALICORNIA UTAHENSIS Tidestrom, Proc. Biol. Soc. Wash. 
26:13. 1913.—A small colony on the borders of Panamint Marsh, 
at a point on the road from Lone Willow Spring to Ballarat (10403; 
May 9, 1915). 
} AMARANTHUS DEFLEXUS L. Mant. 2:295. 1771.—This ama- 
ranth, which is so abundant in the streets of the cities about San 
Francisco Bay, is equally abundant in the streets of Santa Barbara
