me a definite idea as to the appearance of the species, and I soon 

 found a specimen of it in my own herbarium, C. F. Baker's 1348, 

 collected in Clear creek canyon, Ormsby county, distributed as 

 "Lupinits silvestris Drew," an untenable name, for which Dr. 

 Greene had some years before substituted L. Ehneri. It was 

 collected in the mountains west of Carson, and is from the type 

 region. 



Search in the Station herbarium brought to light another 

 collection, Kennedy 1448 from Incline, Washoe county, eleva- 

 tion 6300 feet. This had been determined by Professor Aven 

 Nelson as L. ingratus, Greene, originally described from New 

 Mexican material. 



Last summer I collected it on the east slope of Slide moun- 

 tain, elevation 6700 feet, and, as I recollect, in formation other 

 than granite. Slide mountain proper is composed entirely of 

 granite. The plant was found only in a narrow belt at the ele- 

 vation noted, growing in rather rich soil in the forest where 

 there is considerable undergrowth, and is evidently a woodland 

 species. All of the plants observed had white or creamy flow- 

 ers, but one of Kennedy's from Incline shows flowers with a 

 trace of bine, thereby confirming the original diagnosis. 



The plant is much taller than Watson had supposed, the 

 larger ones being three feet high, and with a considerable 

 spread of branches. The floral parts illustrated in figure 16 are 

 taken from my Slide mountain specimens, no. 10208. 



The leaflets are oblong or oblanceolate, obtuse, the largest 

 4 cm. long, 8 mm. wide, but those that are folded, as many are 

 in drying, appear to be somewhat lanceolate and acute. They 

 are equal to or longer than the petiole. The bracts are lanceo- 

 late-subulate, 4 mm. long, and are fairly persistent, thus appear- 

 ing shorter than the pedicels (5 mm.) of mature flowers. The 

 pubescence of peduncle, pedicel and calyx while short, is rather 

 too prominent to be called "minutely puberulent." The upper 

 calyx lobe is 2-toothed, according to all the flowers examined. 

 As seen in the dried state, the banner appears to be a little 

 shorter than the wings, its sides are not only turned back, but 

 ar<- somewhat inrolled, the face narrow and deeply grooved, es-
