This, and the Nephroma arctica, are the most noble foliaceous Lichens of the Antarctic regions. The present 
is particularly so, the brightness of its golden thallus, and its great abundance on the sea-ward edges of the 
Fuegian forest, rendering it a very conspicuous plant. It is also found in Chiloe and Juan Fernandez, and 
in the Old World it inhabits New Zealand. Though an ally of S. aurata, it is perfectly distinct from that 
plant, especially in the granular and not powdery margins of the thallus, also in size and general features. It is 
certainly as well marked as any species of Lichen confined to the southern latitudes.

This species was not seen at Cape Horn or the Falkland Islands: but we have specimens from Chiloe and 
Juan Fernandez. It is singular that a Lichen, which abounds in Lord Auckland's group and Campbell’s Island, 
should not be also found at Cape Horn; and that the S. endochrysa of Cape Horn is found in New Zealand, 
but does not spread so far south as Lord Auckland's group. The much greater cold of Fuegia might be prejudicial 
to the S. orygmea, but there is no apparent reason for S. endochrysa being foreign to Lord Auckland's group. I 
suspect that the Acharian plant from Staten Land, referred to as 8. orygmea, is the S.endochrysa, Del.; and that the 
specimens were received from Menzies. 2 
There are very remarkable differences between the Lichens of those two divisions of Antarctic botany which 
are here adopted: the most salient features of which consist in the presence or abundance of the following 
Lichens in only one of the divisions. 
LoRD AUCKLAND’S GROUP AND CAMPBELL’S ISLAND. CAPE Horn. 
Usnea melaxantha. 
Ramalina inflata. Ramalina scopulorum. 
Ster lon 7 / Cetraria Islandica.

Sticta orygmaa. í Stereocaulon corallinum. 
Menziesii, Sticta endochrysa. 
Delisea ? crocata.

Freycinetii. 
This remarkable predominance of certain very widely distributed forms in the southern extremity of the 
Western Hemisphere, and the absence of the same in similar positions in the Eastern, admit of no explanation, 
beyond what climate will afford.

Of this we possess an authentically named specimen, gathered and labelled by Menzies himself: in it the 
cyphelle are pale yellow; as Montagne describes those of his S. hirsuta. M.Delise does not seem to have understood 
the species, and describes apparently a very different plant under this name. It is closely allied to the S. cometia 
of Peru, in which the apothecia are fringed with much longer hairs, and also to the S. Humboldtii, Hook., another 
Peruvian plant with fringed apothecia ; but both of these have white cyphelle. 
Sticta obvoluta is also a native of South Chili and Juan Fernandez.
