GRAMINEiE. 485 



14. POLYPOGOK Desf. 



1. POLYPOGON LITTORALIS, Smith. 



Hab. San Francisco, California.— This, in Bolander's distributed 

 sets, was called P. fugax, Nees (P. Monspeliensis, var. fugax, Trin.) ; 

 but later specimens lead me to refer it as above. It seems to be a com- 

 mon grass upon the coast, and grows in similar situations with the P. 

 Monspeliensis, which, though of frequent occurrence, is not in the col- 

 lection. Mr. Bolander states that the present species is much earlier 

 and more abundant than P. Monspeliensis, from which it is readily dis- 

 tinguished by its more open panicle and shorter awns. 



15. G A S T R I D I U M, Beauv. 



1. Gastridium australe, Beauv. 



Hab. San Francisco, California, and since found to be very common 

 upon dry hills in most portions of the State. 



16. AGROSTIS, Linn. 



1. Agrostis scabra, Willd. 



Hab. Gray's Harbor, and common along the California coast. 



2. Agrostis cantna, Linn. 



Hab. Near the mouth of the Spokane River; collected in Cali- 

 fornia by Bolander.
