528 FLORA ANTARCTICA. [Fuegia, the 



Hab. Hermite Island, Cape Horn, and the Falkland Islands; on rocks, &c. Tristan d'Acunka; 

 Petit Thouars. 



The specimens examined, when preparing the short notice of the Antarctic Lichens for the London Journal of 

 Botany, were very imperfect ; and their under-surface exhibiting no cyphellae, we referred them to the S. scrobiculata, 

 which they considerably resemble, especially in colour, and in their fetid scent when moistened. Other specimens 

 showed white cyphellae in abundance, and allied the plant so closely to the European S. limbata, that we can detect 

 no marked difference between them, beyond what is afforded by the colour of the powdery granulations on the 

 surface. 



Delise's description of S. Thouarsii leaves no doubt in our mind of this being his plant. The apothecia are 

 unknown. Fuegian specimens are of a paler colour than the Falkland Island ones.

 Falkland Islands ; very abundant on maritime rocks, &c. Strait of Magalhaens, Port Famine ; Capt. King.

We have added a figure of this much-disputed species, concerning which we have fallen into an error in the 

 previous part of this work, having regarded it as synonymous with the S. glabra of Lord Auckland's group and 

 Tasmania (probably the S. Delisea Fee,), and which differs from the S. Freycinet'd principally in the very shallow, 

 not deeply cupped apothecia. 



Fueria and the Island of Juan Fernandez are the only localities in which we know this species to occur.

Hab. Hermite Island, Cape Horn ; on dead wood. 



Our specimens, which are small and barren, differ in colour and in the less decidedly marked costae, from 

 those of New Zealand ; the lobes also are occasionally furnished with an isidiophorous border. The thallus is 

 about au iuch and a half high, the upper surface of a dirty greenish-brown, the under pale yellow-brown and 

 uniformly covered with a short tomentum, into which the concolorous and rather large cyphellee are sunk. They 

 may, indeed, belong to a state of S. obvoluta, Ach., with the upper surface glabrous ; but hardly to any of the other 

 species enumerated here.

We have before pointed out the singular scarcity, in the Southern Hemisphere, of some of those Lichens 

 which are most abundant in all latitudes of the North Temperate and Arctic Zones. Stereocaulon corallinum 

 affords another remarkable instance of this anomalous distribution. Except, perhaps, the Cenmnyce rangiferina, 

 it is the very commonest of all Lichens in the subalpine districts of Britain and Central Europe, in the Alpine
