This plant is abundantly introduced on the Pacific coast from Vancouver Island to 

 southern California, but apparently not elsewhere in North America. The oldest 

 specimens we have seen hear the date of L886. Collectors have for the most part 

 labeled xtmywrosot microstachys. From the Former it is easily distinguished byita

 icately branching panicle, but shade or diminutive forms simulate bromoides closely. 

 The best distinction in such cases is furnished by the palea. in pacifica the indexed
