2cin. long or less, the raceme equal to or a little longer than the 

 peduncle, the whole barely as long as the leaves: pedicels 2 mm. 



long: bracts subulate, membranous, a little shorter than the 

 pedicel: flowers not verticillate, probably violet-blue, said to be 

 "blue or purple:" calyx with nearly equal lobes, the upper 3mm. 

 long-, 2-cleft into lanceolate bearded divisions, the lower 4 mm. 

 long, minutely 3-toothed, the teeth obscured by the long hairs; 

 the sinus bractless: banner probably little if at all reflexed, 

 broadly ovate when spread out, 5 mm. long, 4 mm. deep; wings 

 moderately inflated, about 3 mm. wide, well rounded on the dor. 

 sal edge; keel blunt and rounded; pods about 12 mm. long, 7 or 

 8 mm. wide, papillose, villous only on the margins, 2-seeded: the 

 seeds large, about 4 mm. across. 



According to Watson the type was collected "near Soda 

 Spring, Candelaria County, Nevada {IV. H. Shockley, May, 

 1886)." A later collection by Shockley (no. 367) is labeled 

 "Sodaville, April and June, 1S88, in open sand." Soda Spring 

 and Sodaville are no doubt one and the same place. These two 

 collections by Shockley are the only known ones from Nevada. 



Watson also cites specimens from "the Mohave Desert, San 

 Bernardino County, California {Parish Brothers, May, 1882).' 

 But the specimens in Mr. Parish's herbarium from the Mojave 

 desert appear to have much larger flowers than the Nevadan 

 type. However, he has a specimen that is more nearly typical. 

 It is no. 96, collected on the "borders of the Colorado Desert, 

 Whitewater, San Diego Co., April, 1882.'' The plant is of the 

 same habit as the type and pubescent like it, but the lower 

 calyx lobe is 2-cleft like the upper one instead of merely mi- 

 nutely 3-toothed. Field study may prove these plants to be dis- 

 tinct.

Since this species is but scantily represented in Nevada and 

 our specimens but doubtfully referred to it at first, I took occa- 

 sion to look "up all the available literature concerning it. The 

 type is apparently in England in the Lambert Herbarium. 

 Pursh described it as follows:
