CATALOGUE OF SPECIES. 181 



Atriplex lentiformis (Torr.) Sitgr, Hep. 169 (1854), under Obione; Wats. Proc. 

 Amer. Acad. ix. 118 (1871). Type locality, "on the Colorado of California." 



This species occurred along the bed of the Amargosa at Saratoga Springs; near 

 Resting Springs (Nos. 261, 265) ; at the mouth of the Vegas Wash (No. 303) ; and in 

 the Tulare Plains south of Bakersfield (No. 1238). Dr. Merriam and Mr. Bailey 

 found it also in Oasis Valley, Pahranagat Valley, and the valleys of the Virgin and 

 Muddy, Nevada, anil in the Santa Clara Valley, Utah. In the southern end of Resting 

 Springs Valley a specimen was seen 4.52 meters long, partly reclining, with a 

 trunk 30 cm. in circumference. 



Atriplex parryi Wats. Proc. Amer. Acad. xvii. 378 (1882). Type locality, "near 

 Colton, California." This locality is undoubtedly incorrect, for the type specimens 

 without ([iiestion came from the opposite side of the San Bernardino Mountains. 



This little known species of greasewood appears not to have been recorded from 

 any place since its iirst collection, but a part of the National Herbarium specimen of 

 Parish Brothers' No. 1350, of 1882, from "Rabbit Springs, Mojave Desert," is the same. 



It was first met with at Saratoga Springs, Death Valley, and until the fruit was 

 examined it was taken to be a peculiar form of Atriplex confcrtifolia. As we after- 

 ward became familiar with the plant it could be readily distinguished from that 

 species not only by the form of the leaves, but also by its general appearance in the 

 winter state. It is smaller than J. confertifolia, has a more evenly rounded form, 

 and bears much more numerous and slenderer branches. The species occurred at 

 Resting Springs (No. 274) ; at Ash Meadows (No. 439) ; about an alkaline dry lake 

 between Ash Meadows and Towner's ranch; on the mesa east and north of Keeler 

 (No. 813) ; on the west shore of Owens Lake ; and north of Searles's, along the margin 

 of the borax flat. In all these localities it occurred abundantly, growing about 

 alkaline lakes or along alkaline stream-beds and usually at a sufficient distance from 

 them to obtain a dry top-soil of drifting sand. Dr. Merriam and Mr. Bailey reported 

 it in Oasis Valley, Grapevine Canon, and Sarcobatus Flat, Nevada, and in Owens 

 Valley, between Lone Pine and Big Pine, California. 



Atriplex phyllostegia (Torr.) in Wats. Bot. King Surv. 291 (1871), under Obione; 

 Wats. Proc. Amer. Acad. ix. 108 (1874). Type locality, "on dry foot-hills and near 

 hot springs, between the Truckeeand Humboldt Rivers, Western Nevada." 



In the first publication cited above the authority for the species is given as Torrey, 

 without reference to manuscript or herbarium, and there is no corroborative evidence 

 in the book to show that the description was furnished by Torrey. But accompany- 

 ing the type specimen in the National Herbarium are enlarged drawings of the dis- 

 sected flowers and some notes in Dr. Torrey's handwriting. It is evident, therefore, 

 that the description is his. 



This was' seen near Saratoga Springs (No. 302) ; at the Mitchell ranch, Resting 

 Springs; near Twelve Mile Spring, Resting Springs Valley; at Ash Meadows ("No. 

 370); and on the east shore of Owens Lake, near Keeler (No. 875). It may be ex- 

 pected almost anywhere in the desert in moist, alkaline, clayey soil, especially in 

 spots where water may have stood during the spring rains. 



Atriplex polycarpa (Torr.) Pac R. Rep. iv. 130 (1857), under Obione; Wats. 

 Proc. Amer. Acad. ix. 117 (1874). Thename was first printed under Obione, without 

 description, in Emory's Report, 149 (1848). Type locality, as taken from the speci- 

 men of the Pac. R. Rep., "hills and gravelly places, on Williams' River," Arizona. 



This greasewood is the common and characteristic one in clayey valley bottoms 

 throughout the Lower Sonoran zone of the desert. Specimens were collected on the 

 south slope of Browns Peak (No. 181), and near Bennett Wells, in Death Valley 

 (No. 196).
