1 cm. long, nearly 4 mm. wide, 3 or 4-seeded, the seeds 3 mm. 

 across, somewhat flattened, whitish or pinkish, smooth. 



As described by Kellogg, this has u a very neat, symmetri- 

 cal stool, of deep lilac blue spikes involved in dense clustered 

 foliage of much beauty, with the aspect of an annual. Found 

 at Donner Lake, summit of Sierra Nevada mountains, Califor- 

 nia, July 14th, 1870." It is still abundant in low sandy ground 

 at the lower end of Donner Lake, where I collected it last July 

 under no. 9829. My no. 6864, collected at the same place in 

 1903, distributed as L. minimus, is this species. There can be 

 no doubt concerning this determination, for Miss Eastwood has 

 compared my specimens with the type. 



Kellogg says the lower calyx lobe is occasionally 3-toothed. 

 His first statement, "stem sufTrutescent, ,, is an obvious error, for 

 the plants themselves do not show such a character, and there is 

 no lupine in this region except perhaps L. Breweri that might 

 be said to have a suffrutescent stem. His later statement, "with 

 the aspect of an annual," is, however, very appropriate. Dr. 

 Kellogg's descriptions are, as a whole, excellent, and one can 

 usually determine his species from them, but occasionally he 

 made statements that can not be reconciled with the facts. 



Lupinus Torreyi Gray, is said to be a synonym of L. con- 

 fertus, and so far as concerns the original, collected by Torrey 

 at Washoe Lake, this is no doubt true, but Torrey 's 89 from 

 near Donner Pass is no doubt L. sellulus. 



L. sellulus is related to L. confertus, but may be easily rec- 

 ognized by its lower stature, more compact growth, and smaller 

 more numerous leaves, which although strongly pubescent, are 

 not so silvery, and by the narrower raceme of smaller flowers. 

 It has as yet been found but sparingly in Nevada, and all the 

 specimens except one are from Washoe county. The exception 

 isJC F. Baker fj/j, collected in Snow Valley, Ormsby county, 

 in 1902, ^distributed as a new species, but fortunately not de- 

 scribed. It differs from material from type locality in having a 

 slightly more open growth, and the lower calyx lobe is minutely 

 3-toothed instead of prominently 2-toothed. The shape of the 

 calyx is the same, and the floral parts are of the same size and
