broadly inflated, the banner is glabrous, more rounded in out- 

 line, the wings deeper, the keel less curved, and the calyx of 

 different shape. The pubescence is practically the same. The 

 flowers are sweet scented. 



This species has an altitudinal range of about 1800 feet. 

 The type was collected well toward the upper limit, which is at 

 about 7500 feet. It inhabits open slopes, growing among the 

 sage brush, and even where thickets of aspen and .Amelanchier 

 occur, is never found in them. 



From about 7500 to 7900 feet was f'umd a purple and white 

 flowered form which does not seem to differ essentially in floral 

 characters. The flowers were less fragrant, the keel slightly 

 more exposed, and the whole plant more pubescent.

The type of this was collected on the "Oregon plains" by 

 Nuttall, and is represented in several eastern herbaria by a piece 

 of the top of a plant showing a rather lax one-sided flowering 

 spike. The semi-spurred flowers have the face of the banner 

 almost concealed by the wings, and have a rounded appearance. 

 The leaves are few and narrow, scythe-shaped. 



In the meadows about Deeth, Elko county, is found :\ lu- 

 pine which Dr. Rydberg says matches closely the original plant. 

 It agrees fairly well with feveral other specimens in the stena- 

 phyllus cover, but I am not certain that these are rightlv placed. 

 While the flower is of the .same type, my specimens are corym- 

 bosely branched, with a rather dense inflorescence of .«;omewhat 

 whorled flowers. The leaves are more numerous, and while nar- 

 row and acute, do not have the same appearance. I am inclined 

 to think that true stenaphyllus ^''\\\ prove to be a northern plant 

 of limited range, but without flowers from the type for dissec- 

 tion, shall refer my plant to it for the present. It is being dis- 

 tributed under number /ojj^.
