ingf a rounded sac at base but not spurred, the whole orbicular- 

 ovate wlien spread out, i cm. broad; wings moderately inflated, 

 about 5 mm. across, depressed and grooved on either side above, 

 the lower edges gradually rounded to the apex, inclosing the 

 keel; keel glabrous, strongly curved, the purple apex slender, 

 the base not narrowed into a stipe: pods (immature?) 2 cm. long, 

 6 mm. wide, densely white villous but the pods them.selves dark, 

 the whole appearing gray, 5-seeded; seeds oblong-ovoid, 4 mm. 

 long, 3 mm. wide, dotted and mottled with brown, some spots

The type, in the herbarium of the Nevada Agricultural Ex- 

 periment Station, is Cusick jjjga, collected August 5, 1909, in 

 the Wallowa mountains, on the banks of West Eagle creek, 

 Baker county, Oregon, altitude 5200 feet. Air. Cusick writes 

 that it is very abundant in the Wallowa and Blue mountains of 

 Oregon at altitudes of 5000 to 7000 feet, growing in dense, large 

 masses on stream banks. 



While averse to describing fragmentary material, the type 

 consisting of two flowering tops, a fruiting spike and a basal leaf, 

 I have been unable to obtain better material. This species has 

 been referred to L. polyphylhcs^ but differs considerably. It has 

 smaller flowers, much larger bracts, longer and acuter calyx 

 lobes of quite different shape, a narrower flower, the banner with 

 a deeper sac at base, and above all, in the stipeless keel, an un- 

 usual feature. Of the known species, it is probably related to 

 L. Burkci.
