Decidedly the most Antarctic of Ferns, occurring only at the very extremity of the American continent, where 

 it is tolerably abundant in the woods.

Hab. Var. /3. South part of Tierra del Fuego, C. Darwin, Esq.; Hermite Island, Cape Horn, /. B. H. 



A species exhibiting a singular predilection for those insidar and peninsular localities, which terminate the 

 continents in the Southern Ocean. Thus it occurs only at the very southern extremity of America and Africa ; at 

 Ceylon, which is nearly the southernmost land of the vast Indian empire ; in Tasmania, which is an analogous 

 position in Australasia ; and in New Zealand and Lord Auckland's group, which bear the same geographical 

 relation to Polynesia. As it also inhabits Bourbon and the Mauritius, it appears to exist all round the world, 

 resting on the highest southern lands of each longitude.

Hab. Falkland Islands; Gandichaud, D'Urville. 



A plant which I have never seen, though I diligently sought for it in the Falkland Islands. It is remarkable 

 that both the French Naturalists who met with it, should have faded to notice the Hymenophyllum Wihoni, which 

 is sufficiently abundant, and generally accompanies the following species.

This singular little species was discovered by the lamented Menzies, in Staten Land. Cape Horn is its southern 

 limit, and Chiloe its northern. It has been probably overlooked in the intervening latitudes.

One of the most extensively diffused of all vegetables, or even Ferns, though avoiding such hot and equable 

 climates as the low lands of the Tropics. In America, it ranges along the Cordillera, from the Arctic Sea and 

 Greenland to the Strait of Magalhaens ; in Europe, from Iceland and Lapland to the Mediterranean ; in Asia, 

 between Kamtschatka and the Himalaya Mountains ; but in Africa it is confined to the Canary Islands and the Cape
