88 BOTANY OF THE DEATH VALLEY EXPEDITION. 



is a small-leafed form resembling the prevailing northern forms of this species as 

 found m Montana, Idaho, and Washington. 



Astragalus triflorus Gray, PI. Wright, ii. 45 (1853), Type locality of Gray's 

 plant, "sandy hanks of the Rio Grand.', below El Paso." The I'haca In flora of De 

 Candolle, Astrag, 50 (1802), appears, from an examination of the original descrip- 

 tion and plate, to he clearly a different plant. It came from Peru. 



In Furnace Creek Canon (No. 3G3), and on the western slope of the Charleston 

 Mountains {No. 373). 



Astragalus virgineus Sheldon sp. nor. 



Annual, erect, 5 to 10 cm. high, loosely branching, pubescent throughout with short 

 spreading hairs; leaves2.5 to 3.7 cm. long; leaflets 3 to 6 mm. long, obtuse; stipules 

 triangular-acute; peduncles as long as the leaves; racemes short-capitate, 3- to 6- 

 flowered; flowers small, 4 to 6 mm. long; calyx teeth subulate, spreading, longer than 

 'the subcampanulate tube, corolla ochroleucous; pod 6 to 10 mm. long, coriaceous 

 obovate, one-celled, transversely rugose, sessile in the calyx, woolly pubescent with

Type specimen in the United States National Herbarium, No. 1910, Death Valley 

 Expedition; collected May 6, 1891, below St. George, in the valley of the Virgin 

 River, Lincoln County, Nevada, by Vernon Bailey. 



The species is nearest to AsWagalm aridus Gray, but is much lower and has a 

 shorter, non-gibbons jiod. 



Glycyrrhizalepidota Pursh, Fl. ii. 480 (1814). Type locality, "on the banks of 

 tlic ,M issouri." 



No specimens of Glycyrrhiza were collected west of the Sierra Nevada although 

 thoy were abundant near Visalia. The plant occurring in that region is probably 

 the variety glutiuoHa. The fruit of this species, covered as it is with hooked 

 spines, resembles the fruit of Xanthium Ktnnnarium, and like it is very annoyin^ in 

 the manes and tails of horses. 



The plant was recorded from Pahrump Valley, Ash Meadows, Lone Pine (No 895) 

 Olancha, South Fork of Kern Riyer, and Tehachapi Canon. It grows best in rich' 

 moist, slightly alkaline loam. ' 



Vicia califomica Greene, Fl. Fran. 3 (1891). Type locality, "Calaveras Co.," 

 California. 

 Tehachapi Valley (No. 1120). 



Lathyrus paluster L. Sp. PI. ii. 733 (1753). Type locality European. 

 Grapevine Mountains (No. 17G0). 



Cassia armata Wats. Proc. Amer. Acad. xi. 13G (1870). Type locality, "in the 

 mountains of S. California, between Fort Mohave and Cajon Pass." 



This was first seen between Stoddard Wells and Daggett (No. 133). It occurred 

 in the vicinity of the latter place and northward in the desert about 15 miles nearly 

 to the first high divide. Afterward it was found again along the northwest foot of 

 Pilot Knob, at Lone Willow Tanks, at the south foot of Hrowns Peak, in Loim- Val- 

 ley, on a spur of the Funeral Mountains between Saratoga Springs and Amargosa 

 and on the eastern slope of the same range, west of the latter place. Dr Mcniam 

 reported the plant also from Leach Point Valley and the great bend of the Colo- 

 rado Riyer. Its habitat is usually the dry, sandy beds of shallow washes in the 

 open desert, and its common companion is llpnenodea mhola. It cannot be con- 

 sidered an abundant shrub, yet over a comparatively restricted portion of the desert 

 it occurred frequently. The species is particularly interesting in the fact that 

 while belonging to a characteristically tropical and subtropical genus, the species
