Tricuspis pulchella (Ton*.) 

 Southern California, (Doctor Cooper.) 



TESTUCACE^. 



Poa annua (Linn.) — Low spear grass. 



Moist places everj^whei-e ; useless. 



Poa pratensis (Linn.) — Green meadow grass. 



Meadows at Oakland, sparingly. It seemed to do very well. Roots 

 stoloniferous ; perennial; April. Thrives best on rather dry meadows. 



Poa trwialis (Lin.) — Rough meadow grass. 



Sparing in meadows, more frequently on dry hillsides, especially 

 among the chapparel of the Coast Range. It is doubtful whether this 

 grass has been introduced. April; useless? 



Poa (?) 



Collected at Eureka, by Mr. Schmitt. Too little known to me. 



Atropis Callfornica (Munro) — Squirrel grass. 



"The foliage very fine, and considered of no value. Comes in after 

 the wild oats have become exterminated by close feeding." — (Professor 

 Brewer.) Very common throughout the State; perennial; March, April. 



Brizopyriim Douglasii (Hook.) 



On drifting sand west of San Francisco, and near Bolinas Bay. It is 

 a low, beautiful, dioecious, perennial grass, with extremely long runners, 

 which are well adapted for fixing the loose and flowing sands advancing 

 with fatal sureness upon our city. April ; as a fodder grass, useless. 



Brizopyrum spicatum (Hook.) — Spike grass. 



Salt marshes near the Bay of San Francisco, and upon saline soils in 

 the interior. Useless for agricultural purposes. April. 



Briza media (Lin.) — Quaking grass. 



Borders of a run near Mission Dolores. Of the same species I received 

 some time ago a panicle from Owen's Valley. It seems to have been 

 but lately introduced. Of little value. May; annual. 



Glyceria nervata (Trin.) — Manna grass. 



Sierras and Mendocino County. Useless.
