spike smaller, nearly sessile : pistillate spikes shorter and 

 thinner, lighter colored, shorter stalked, the upper 2 or 3

 obtuse, usually shorter: perigynium not so long and 

 slender-beaked. Western Territory.' ' — No mention is 

 made of the probable affinity with Boott's C. luzulcefolia, 

 or of the possible identity with his C. Lemmoni. This 

 seems the more curious when this same author (L. H. 

 Bailey) in the following year proposes his G. albida as an 

 ally of C. luzulina Olney, 11 with no reference to G. luzulce- 

 folia Boott or to G. ablata Bail., not speaking of the true 

 C. Lemmoni W. Boott. 



Having had access to a number of specimens identi- 

 fied by Professor Bailey himself as representing G. ablata 

 we naturally depended on the correctness of the determi- 

 nation. But some years ago, when called upon to name 

 some Californian Garices, we came across the so-called 

 C. Lemmoni, and being unable to identify this by means 

 of comparing the original diagnosis, we submitted the 

 specimens to C. B. Clarke. Again it is through the kind- 

 ness of this excellent botanist that the difficulty became 

 removed, and we were informed that Boott's C. Lemmoni 

 had been sent to Kew as C. ablata Bail., while the 

 so-called C. Lemmoni was an undescribed species for 

 which Clarke proposed the name cequa; it was based upon 

 material collected by C. F. Baker in California: San 

 Mateo (n. 811). 



To prevent future difficulty regarding the identification 

 of C. Lemmoni W. Boott we might reprint the original 

 diagnosis: "Csespitosa. Culmis 2 ped. altis, latere y 2
