 1889); no locality (C. L. Anderson 120 in 1888; 76 in 1888; 9(5 in 1888— this 

 specimen is about identical with specimens in the Gray herbarium from Doug- 

 las's collection which are evidently typical; 109 in 1888); Bear Valley, San 

 Bernardino Mountains (S. B. Parish 3298 in 1894); San Bernardino Valley (S. 

 B. and AV. F. Parish 1534 in 1882); San Gorgonio (S. B. and W. F. Parish 1533—

 1895); near INIount Shasta (E. Palmer 2626 in 1892— this is the form which 

 Nuttall called Bnmmn oregoniift; it differs from typical B. (■anriatun in its somewhat 

 broader glumes and slightly denser pubescence); southeastern California ( E. 

 Palmer 546 in 1896); New York Falls (Geo. Hansen 627); Berkeley (J. Burtt

35rr. BROMUS CARINATUS CALIFORNICTJS (Nutt.) n. (•(.nib. Bromits 

 califomicus 'Nutt. in Herb. Acad. Nat. Sci. Phil. 



A form intermediate between typical B. rarinafu-'^ and B. cnrinafn.^ Iindkcrkwui^. Dif- 

 fering from the former in its nearly smooth leaves and sheaths and its flowering 

 glumes merely scabrous. From the latter it differs in its narrower spikelets and 

 glumes. 



Nuttall's specimen in the Philadelphia Academy herbarium labeled "u. Calif." is a 

 mere scrap showing only two small ]>anicles from different ]>lants and having a 

 few small upper leaves. This form must be near li. Jionkcrl sHiajfneri Fourn, 

 judging from his description. 



The following specimens from southern and Lower California have been referred to 

 this variety. Loirer Calif ornia: Todos Santos Bay (Miss F. E. Fish 12); Potrero 

 Valley (C. R. Orcutt, in 1889). California: San Diego (D. Cleveland 13); (C. R. 

 Orcutt 511a).

A robust plant, larger in all its parts than the species. Panicles erect, 2-4 dm. long; 

 branches spreading. Spikelets 5-10 flowered, 3-4 cm. long, 5-7 mm. broad; 

 empty glumes slightly broader and less ai'ute than in the species; flowering 

 glumes also broader and scabrous with a broad hyaline margin and an awn 10-15
