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.

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

This plant I believe 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
