long, pale, falling away early: pedicels slender, i cm. long, short 

 villous, as is the calyx: upper calyx lip 8 mm. long, split at the 

 apex for 2 mm., the sinus closed, the whole broadly lanceolate 

 when spread out, 4mm. wide at base; lower lip shortly 3-toothed, 

 oblong when spread out, 4 mm. wide at base, nearly 2 mm. at 

 apex: corollas 13 mm. long and as deep, distance between apices 

 of banner and wings 7 mm.; banner with edges turned back and 

 parallel, violet, lower part of the face yellow with purple dots, 

 the middle and upper parts white, the whole orbicular when 

 spread out; wings violet but paler on the sides, moderately in- 

 flated, completely inclosing the keel, united for 5 mm. at the 

 apex, 9 mm. deep across the middle; keel sparingly short ciliate 

 on the lower half, 4 mm. deep at the middle, strongly curved, 

 the apex purple: fruit not seen. 



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

 periment Station, is Heller 10042, collected May 18, 1910, near 

 Eugene, Lane county, Oregon, along the railroad in low, moist, 

 grassy places. 



It is a handsome species, the well rounded clumps covered 

 with large violet and white flowers presenting a pleasing appear- 

 ance. The casual ob.server would probably fail to note the true 

 character of the plant, for the trailing woody stems are hidden 

 in the grass. Its nearest relative is L. variicolor, from which it 

 differs in much greater size, heavier woody branches, larger and 

 more succulent herbaceous stems, narrower aud paler bracts, 

 narrower and more silky calyx, and larger and paler flowers. 



There is a specimen of it in my variicolor cover, H. E. 

 Brown yi8, collected near Mendocino, California, June, 1898. 

 In 1898 I collected it at Montcsano, western Washington, and 

 distributed it as L. littoralis. The plant from "Crescent City," 

 Del Norte county, California, collected by Howell, and men- 

 tioned by Greene when describing L. propinquus (Erythea 1: 

 126), is also this species.
