 Davy in Jepson, Fl. W. Mid. Cal. 36. 1901. Dr. Stapf, who has examined the type specimen 

 of 1'. calif ornica at Kew, informs me that it is the species that has been called Phalaris amethys- 

 tina by California botanists, but which he considers distinct from that species, the type of 

 wliich is from Chile. I have examined tlie type specimen of P. amethystina in the Trinius 

 Herbarium and agree with Dr. Stapf tliat it does not belong to tlie same species as our Cali- 

 fornia plant. The glumes are shorter and scabrous. (F. ameihysUna Trin. Mem. Acad.
