 1-2 dm. long, lax: flowers scattered ; pedicels and calyx densely 

 pubescent with short strictly appressed silky hairs ; lower lip of 

 the calyx about 5 mm. long, lanceolate, almost twice as long as 

 the short ovate upper one : corolla yellow or light pink ; banner 

 slightly exceeding the wings, with a few short hairs on the back, 

 with a darker spot, about 8 mm. long : pods densely silky pubescent. 



This species is nearest related to L. sulpJnircus, but differs in 

 the more silvery pubescence, the smaller flowers and the appressed 

 pubescence of the calyx and pedicels. The type grew at an alti- 

 tude of 1900 m.
