Notes on Fournier's Mexican Species and Varieties of Bromus 



* 



By C. L. Shear 



In the spring of 1900, Mr. A. H. Baldwin, an artist of the De- 

 partment of Agriculture, then employed in the Division of Agros- 

 tology, visited Paris and while there examined some of the speci- 

 mens of Bromus cited by Fournier and preserved in the Herbarium 

 of the Museum of Paris. Through the courtesy of the Director 

 he was permitted to make sketches of these plants and to take 

 spikelets from each ; he also made notes in connection with his 

 sketches, and by aid of these it has been possible to identify some 

 of the forms treated by Fournier. While there is still much to 

 be desired in order to make a thoroughly satisfactory disposition 

 of the Mexican species, it is thought best to present the informa- 

 tion thus acquired in the hope that it may be of some use to 

 students of Mexican grasses. 



With the exception of Ceratochloa festucoides the species and 

 varieties are taken up in the order in which they are given by 

 Fournier in his work. 



Bromus exaltatus Bernh. Linnaea, 15 : Lit. 90 



B. subalpimis Rupr. Bull. Acad. Roy. Brux. 9: 237. 1842, is 

 cited as a synonym of this. Consultation of this citation shows 

 this name to be a nomen nudum. A comparison of three of the 

 specimens cited by Fournier (Gal. 5769 & Liebm. 488 and 501) 

 with the original description of Bernhardi leaves considerable 

 doubt as to whether they are correctly referred. Only an exam- 

 ination of the type which we have been unable to locate will 

 decide the question. Dr. Trelease informs me that it is not in the 

 Bernhardi Herbarium. No. 925, C. L. Smith, Sierra de San 

 Felipe, Sept., 1894, seems to belong here. 



Bromus anomalus Rupr. Fourn. Mex. PI. 126. 1886 

 This is attributed to Ruprecht in Bull. Acad. Roy. Brux. O 2 : 



* Fournier, Mexicanas Plantas, etc., Pars secunda. Graminae, 125-128. 1886.
