single station in his Fl. State Wash. | [906). Howell, Fl. X. W. 



Am. 770. 1903, notes it indefinitely "in waste- places," and Shear 

 1S1 had but one specimen from Oregon and none from further 

 north. In this state it is abundant, as indicated by its represen- 

 tation in herbaria. Shear(8) cites specimens showing a range 

 from Amador to Santa Ana, and Jepson's Flora two from the 

 western middle counties. In the southern part of the state it 

 has a history and records similar to those already given for />'. 

 maximus: Davidson, Erythea 1: 101. 1893, "increasing rapidly; 

 PI. Los. Aug. Co. 32. 1896; Bull. S. Cal. Acad. 6: 11. 1907. — 

 McClatchie, Fl. Pasad. 629. 1895, "Devil's Gate."— Abrams, Fl. 

 Los Aug. 54. 1904, "common in sandy soil." 



In addition to the bromes already considered three others 

 have been reported from onr region. B. madritensis was found 

 for the first time in North America in 1887 at Ft. Tejon, in 

 Kern count}'. It was there and then well established, monopo- 

 lizing a large tract of arid soil. Abrams(J)) has since reported 

 it from the Santa Ana mountains, on the San Diego trail, and 

 according to Shear (IO) it is rather widely distributed in Cali- 

 fornia. In addition to the Ft. Tejon station he cites San Jose, 

 Antioch, and Amador county, and according to Howell (11) it 

 also is found in Oregon. 



In 1905 a few clumps of B. arenarius were found on the 

 Arrowhead road, in the San Bernardino mountains (1*4). Fin- 

 ally we have a single report of the occurrence of chess, B. seca- 

 liiuts, in southern California. It is noted as "rare" at Glendale, 

 near Los Angeles (13). It seems remarkable that so common 

 a species should not be frequently found in grain fields. 



What may be the future of these now rare species cannot be 

 predicted. Perhaps by the end of another period of twenty 

 years, botanists may find them as abundant as are now those 

 which twenty years ago were just beginning their career of con- 

 quest. And it will be cause < f congratulation if they are not 

 obliged to add some other of ilie worthless European bromes, 

 such as /,'. teciorum, B. stcrilis, B. asper^ and />. racetnosus y 

 which are wed established in various parts of the United States, 

 and of which all but one have already appeared on the Pacific 

 coast.
