Flora of Los Angeles, p. 23, from San Jacinto mountains, and

BROMUS ARENARIUS Labill, Pl. Nov. Holl. 1: 23. Ad. 28. 
A few clumps of this Australian grass were found growing 
along the Arrowhead road, at about 1000 m. altitude, in the San 
Bernardino mountains, June 14, 1905, by Fred M. Reed and the 
writer. Perhaps little more than a casual, but in view of the 
facility and rapidity with which the introduced bromes have 
spread in southern California, it may be expected to establish 
itself. A foreign grass would hardly be expected to make its 
first appearance in America by the side of an obscure mountain 
road. It seems, therefore, not improbable that the present is a 
secondary introduction, and that the plant has obtained a pri- 
mary foothold in some place where commerce might more easily 
scatter the seed, but where it has not yet happened to have met 
the eye of a botanist. Identified by Professor Hitchcock.
