MACLOSKIE: REVISION OF FLORA PATAGONICA. 35 



was, in fact, no very good reason. The specific name antarcticus is older 

 than alpinus, and, besides this, there is really a certain small difference 

 between these two, the awns being much larger in A. antarcticus than in 

 A. alpimis. I therefore think it will be more correct to note the latter as 

 a variety of the former. Macloskie separates them, and also names A. 

 antarcticus var. alpinus (A. alpinus Sm.) ; but A. antarcticus var. alpinus 

 (A. alpinus Sm.) is an arctic plant and not known from S. America, and 

 should therefore be eliminated from his explanation. D. 



Yesterday when visiting (June 30, 1913) Upsala I called Skottsberg's 

 attention to his opinion about Alopecurus fuhus, geniculatus, and alpi- 

 nus, but he ultimately expressed himself as agreeing with what I had 

 written. D. 



Alopecurus antarcticus Vahl. (Macl., p. 179) is the right name, A. 

 magellanicus and A. alpinus v. aristatus Hook. fil. being synonyms. 



Alopecurus Lechleri Steud. Mel., p. 180, is undoubtedly only a form of 

 A. antarctictis. Skottsberg does not regard A. geniculatus L. as merely 

 a synonym of A. alpinus Sm.

 S. Patagonia, in the upper valley of Rio Gallegos (Dusen). 



SPOROBOLUS R. Br.

S. ARUNDINACEUS Gray. 



Should be transferred to the next genus. 



S. INDICUS R. Br. Macl., p. 181. 

 This species is not known from Patagonia and, consequently, should be 



deleted.

 empty glume ; the awns minute, subterminal, slender. Rachilla not pro
