370 FLORA ANTARCTICA. [Fuec/ia, the 



Valparaiso, and Conception, again at Yaldivia, finally disappearing at the Chonos Archipelago. Though we are 

 now fairly acquainted with the botany of America south of lat. 33°, a more complete collection from the coast and 

 mountains between the southern extreme of Chiloe and Cape Tres Montes is wanting; the proportion of new 

 species would probably be small, but the investigation would exhibit the range of many Yaldivian and Fuegian plants, 

 not contained in the invaluable Herbarium of Mr. Darwin, the only naturalist whose good fortune it has been to 

 visit and explore that unfrequented line of coast.

Hab. Falkland Islands ; Gaudichaud. 



When botanizing in the Falkland Islands early in the winter of 1841, I found what I considered to be this 

 plant, growing amongst grass in wet spongy bogs ; it was, however, in a very bad state, and the specimens, unfor- 

 tunately, lost. 



Brongniart unites this with U. plileoides, Pers.; but M. Kunth has kept it distinct.

This plant I bebeve to be specifically the same with the North-European and American A. alpinus, of which 

 Smith considered it to be a variety. What appeared specific differences, were pointed out by Mr. Brown {in Appendix
