pedunculate, the flowers scattered or subverticillate ; flowers "fragrant", 4 to 7 

 lines long; pedicels 2 lines long; calyx-lips somewhat unequal, the upper shortly 

 cleft, the lower 3-toothed, or sometimes only obscurely so; petals blue, pale lavender 

 or white, the banner with a yellow center changing to dark violet or dark purple ; 

 keel ciliate; pods densely pubescent, 1 to II/2 inches long, 5 to 8-seeded. 



Flood beds of streams and washes, and on tilted mesas, 2600 to 6600 feet: 

 Inyo Co. May- June. 



Field note. — In the desert canons of the Panamint Eange, opening into Death Valley from 

 the west, this floriferous species, at about 3500 to 4000 feet, is seen in its best development. The 

 bushes, 3 to 4 feet high and 4 to 8 feet broad, are in May crowned each with hundreds of racemes 

 and make a fine spectacle in the washes and on the neighboring hill-slopes. The pale lavender- 

 blue flowers, borne in long racemes, are elevated on rather long peduncles and add to the happi- 

 ness of the specific name.
