 fornia; the shorter one, Brewer 1077, Mount Diablo, California, tin- details from the former. Plant

7. Festuca microstachys Nutt. 



Festuca microstachys Nutt. Journ. Acad. Phila. n. s. 1: 187. 1847. "Pueblo de los 

 Angeles, Upper California." 



We have been unable to locate Nuttall's type specimen. It is not at Kew nor in 

 the Philadelphia Academy of Sciences. Nuttall's description, however, is so com- 

 plete that it ia hardly possible to mistake the plant.
