 smoother above, the petioles but little longer ; raceme 2-3' long, 

 5 - 10-flowered, rather long-peduncled ; bracts short, subulate ; pedicels 

 1 - 2" long ; calyx silky-pubescent, minutely bracteolate, upper lip 

 parted, the ovate acute lobes nearly equalling the broad entire lower 

 lip ; petals 6 - 1" long, the yellow banner shorter than the rose-colored 

 wings ; pod slightly puberulent or glabrous, 1' long. — In the Sierra 

 Nevada, from Bear Valley to the Yosemite ; a handsome and well-

48. L. hirsutissimus, Benth. Rather stout, 1° high or more, very 

 hirsute with spreading, straight, and viscid " stinging " hairs ; leaflets
