monly lilac-purple, sometimes darker, 6 mm. long, 5 mm. deep, 

 the -apices of banner and wings only 1 mm. apart. The banner 

 has a yellow spot, as described, its sides turned back, the edges 

 almost meeting, the face narrow with a deep groove, nearly con- 

 cealed by the wings. The wings are broadly inflated, deeply 

 and shallowly furrowed along the lower half of the upper edge 

 where they fit into the groove of the banner. The slightly pro- 

 truding keel is curved almost at right angles, sparingly short 

 pubescent toward the stout and bluntly pointed apex, 2.5 mm. 

 deep at the middle. 



Figure 19. Floral parts of Lupirms meionanthus, enlarged. 



The above notes, the cover illustration, and the drawings 

 of the floral parts were taken from my no. 9773, collected in 

 coarse granite sand on forest slopes back of Franktown, which 

 is in the type region, only a few miles north of Carson. It is 

 rather common in the Sierra Nevada in both Nevada and adja-
