 A. ALPINUS Sm. var. ANTARCTICUS (Vahl). 

 Syn. A. antarcticus Vahl ; A. magellanicus Lam. 

 There is, in fact, very little difference between A. alpinus Sm. and A. 

 antarcticus Vahl, as E. Hackel informs me. The last mentioned usually 

 is higher ( i m. or still more) and has much longer awn than the former. 

 Its spike varies in length and thickness and the color of the glumes is 

 also varying. The A. alpinus itself sometimes attains a considerable 

 height. The only character of any importance separating them is the 

 much longer awn of the glumes in A. antarcticus. This difference, how- 

 ever, scarcely gives sufficient reason for separating them specifically. A. 

 antarcticus, therefore, may be placed as a variety of A. alpinus.
