Setaria californica Kellogg Proc. Cal. Acad. Sci. 1: 26 (1873). Collected at 

 Shasta, on the Sacramento Eiver, and described as being about 12 feet high, with 

 erect, cylindrical spikes a foot long, with densely villous rachis, and smooth 

 flowering glume. From the description and the fact that this prominent form 

 has not been collected since, there can be little doubt that it was a form of 

 ChRtochloa italica, escaped from cultivation but not persisting.

 purascens.
