66 PATAGONIAN EXPEDITIONS : BOTANY. 



deum pratense Brongniartii (Wad.., p. 251) is a complete verbal translation 

 of H. secalinum Schreb. var. chilense (Brongn.) Desv., as given by Des- 

 vaux in Gay, Flor. Chil., VI, p. 458. Also by oversight Macloskie gives 

 one and the same plant, viz., H. secalinum var. chilense (Speg., Prim. 

 Flor. Chub., p. 630, in collibus siccioribus) as belonging both to Hordeum 

 chilense Brongn. and to H. pratense Brongniartii Macl. 



Hence we must delete from Macloskie's list H. pratense, H. chilense, 

 H. pratense Brongniartii and H. pratense chilense, deleting the first of 

 these, and absorbing the other three in H. secalinum var. chilense (Brongn.) 

 Desv. This occurs in E. Fuegia ; Patagonia, in the steppe from its north- 

 ernmost to its southernmost section ; hitherto, however, not known from 

 the coast-district. D.

ELYMUS L. 



E. ERIANTHUS Phil. Anal. Mus. Nac. Chile, 1892, p. 13, t. 3, fig. 3. 



Syn. Elymus Spegazzinii F. Kurtz. 



Elymus erianthus Phil. syn. E. barbatns; but this name must be replaced 

 by E. Spegazzinii, as E. barbatus seems to be only a manuscript-name. 

 Hooker and myself have not succeeded in finding this name in the litera- 

 ture, and enquiry of Mr. Kurtz has not brought us any answer. D. 



E. Patagonia, Puerto Mazaredo in bushy steppe ; S. Patagonia, near 

 Sta. Cruz emporium in the steppe, by Lago Viedma on drift-sand, in the 

 mountains between Lago Viedma and Laguna Tar.
