Brief notes are given on several forage plants which seem promising 

 for different parts of the State. Aristida oligantha is considered an 

 excellent grass, and what, from an incomplete specimen, appears to be 

 Bromus sterilis is also considered promising for the sage-brush lands in 

 certain parts of the State. 



Notes are given on several weeds and on an unidentified fiber plant 

 said to occur very abundantly in Monterey County. The latter will be 

 further investigated.
