A. ALPINUS Sm. var. ANTARCTICUS (Vahl) f. LECHLERI (Steud.). 

 Syn. Alopeciirus Lechleri Steud. Syn. Glum., I, p. 148. 



It is, in my opinion, impossible to separate, at least specifically, A. 

 Lechleri Steud. and A. alpinus Sm. I have had the opportunity of 

 examining two specimens of the first mentioned collected at Valdivia or 

 not far from there. The one has the upper part of the culm naked ; in 

 the other the culm is sheathed quite up to the spike. Other differences 

 do not exist. Both specimens are characterized by narrow, subconvolute 

 and subpungent upper leaves and very small spike. The same form was 

 observed by me in the beech forests by Lago Argentine, Lago Viedma 

 and Lago San Martin and probably occurs in the whole district of A. 

 alpinus var. antarcticus. 



The two specimens now in question belong to the collection of Chilian 

 plants made by W. Lechler and distributed by R. F. Hohenacker. The 

 one (No. 440) is determined as A. Lechleri Steud., while the other (No. 

 532) is labelled A. alpinus Sm. They represent, however, evidently only 

 one form standing very near to A. alpinus var. antarcticus and differing 

 merely by its comparatively small spike and upper leaves being subcon- 

 volute, subpungent and narrower than in the var. of A. alpinus Sm. In 

 my opinion the present plant represents only a form of A. alpinus var. 

 antarcticus; it occurs in the forest district of S. Chili and probably of the 

 whole of W. Patagonia, but scarcely outside the forest. D.

A. geniculatus Linn, but with awn from base or middle of inner valve ; 

 stem ascending, knee-jointed ; thyrse compound-cylindrical ; glumes

 In my explanation of the Fuegian and Magellan vegetation, "Die Gefass-

 and A. antarcticus Vahl., under the name of A. alpinus, but for this there
