Mr.Caldeleugh sent home two tubers, which, being well manured, even the first season produced numerous potatoes and an abundance of leaves.

See Humboldt's interesting discussion on this plant, which it appears was unknown in Mexico,--in "Political Essay on New Spain" book 4 chapter 9.) It is remarkable that the same plant should be found on the sterile mountains of central Chile, where a drop of rain does not fall for more than six months, and within the damp forests of these southern islands.
In the central parts of the Chonos Archipelago (latitude 45 degrees), the forest has very much the same character with that along the whole west coast, for 600 miles southward to Cape Horn.
The arborescent grass of Chiloe is not found here; while the beech of Tierra del Fuego grows to a good size, and forms a considerable proportion of the wood; not, however, in the same exclusive manner as it does farther southward.

Cryptogamic plants here find a most congenial climate.

In the Strait of Magellan, as I have before remarked, the country appears too cold and wet to allow of their arriving at perfection; but in these islands, within the forest, the number of species and great abundance of mosses, lichens, and small ferns, is quite extraordinary.
