Allium serratum Wats. 



No. 7861, collected May 26, on dry hills west of Redding, 

 Shasta county, under trees. This form has smaller deeper col- 

 ored flowers than those from Kern county. The writer is of the 

 opinion, based upon field observations, that several species are 

 included under this name, and that the distinctive characters in 

 this case are found in the flowers rather than in the markings of 

 the bulb coats.
