Rostkovia magellanica (Lam.) Hook. f. appears to be the proper name 

 of Lamarck's species, first named by him Juncus magellanicus (Lam. 

 1798); next Rostkovia sptuzrocarpa Desv. (1808), and afterwards Rost- 

 kovia magellanica (Lam.) in Hooker's Flora Antarctica. 



JUNCUS L.

Represented in our district by the typical plant as well as by the varie- 

 ties europcBus Engelm., litoralis Engelm. and mexicanus (Willd.) Ok. 

 (= J. mexicanus Willd.). 



The typical plant itself is undoubtedly the commonest of these forms. 

 It occurs not seldom abundantly on the more or less saliferous grounds 

 of the river-valleys, at least in S. Patagonia. 



J. BUFONIUS L. Macl., p. 298. 

 Not rare, at least in S. and Central Patagonia ; also in the Falklands 



Ids. 



J. CHAMISSONIA Kunth. Macl., p. 298. 



Is to be transferred to y. imbricatus Laharp as a variety of that species. 







J. CYPEROIDES Laharp. Macl., p. 298. 



Syn. y. graminifolius E. Mey. 

 Also in W. Patagonia, Chonos Archipelago. 



J. DEPAUPERATUS Phil. Macl., p. 298. 



Should be deleted. Dusen's earlier statement of the occurrence of this 

 species in Fuegia based on Buchenau's determination of his specimens is 

 not correct. These specimens belong to y. inconspicuus D'Urv. of Pflan- 

 zenreich June., p. 169. D.
