Falklands, etc.] CRYPTOGAMIA ANTARCTICA. 227 
Haz. Hermite Island, Cape Horn; from the sea to the mountain tops. Falkland Islands; very 
abundant. Var. 8. barren rocks near the top of Kater's peak. 
This species was also found abundantly in Lord Auckland’s group and Campbell’s Island, though omitted in the 
first part of the Flora Antarctica. It is further a native of New Zealand and Tasmania; of North-west America, 
from California to Sitka, and we possess a specimen labelled as from the Mauritius. 
Specifically, this differs from P. physodes only in the length of the lobes of the thallus, and these are so variable 
as to lead to some doubts of the validity of the species. In Tasmanian specimens the lobes are often much dilated 
and plane, the membranes of which it is composed, and which are normally inflated, being here, not only in contact, 
but firmly united together; thus effecting a passage between this species and the forms to which P. perlata, ۰ 
belong. 
We have authentically named specimens of the North-west American P. physodes, ß. vittata, which is only a 
narrower state of P. enteromorpha. Norwegian specimens also of the latter plant appear to be clearly referable to this.

Has. Hermite Island, Cape Horn; on stems of bushes and on branches of trees, on the mountains. 
Chonos Archipelago, C. Darwin, Esq. 
Probably only a small, or alpine, form of P. enteromorpha ; 14 was found in similar situations in Lord Auckland's 
group, and on the top of Mount Wellington in Tasmania. Besides being a native of Great Britain and alpine 
situations in northern and midland Europe and of the Sandwich Islands.

Haz. Staten Land, Menzies. Hermite Island, Cape Horn; on rocks and trunks of trees above the 
limit of the evergreen Beech. 
By the apothecia this beautiful species may be distinguished, both from P. diatrypa and P. enteromorpha, some 
of our specimens, indeed, are on the same piece of wood with P. diatrypa, both retaining their characters. They 
entirely agree in every other respect with one collected by Menzies, except in being of a pale lemon colour.

4. PARMELIA sazatilis, Ach.; Synops. p. 203. Engl. Bot. t. 603. Mougeot et Nestler, n. 347 and 738. 
Has. Hermite Island, Cape Horn, and the Falkland Islands; abundant on alpine rocks. Cockburn 
Island, Graham’s Land; very scarce. 
None of these specimens are in fruit, but they accord perfectly with Scottish and other European examples. 
The lobes of the thallus vary a good deal in size and colour, according to exposure. What is believed to be this 
plant was seen at Cockburn Island, on the verge of Antarctic vegetation, but, as the specimens were lost 
previous to comparison, some doubt may be entertained of the correctness of this habitat. Besides being abundant 
throughout Europe, advancing as far north in Spitzbergen as vegetation extends, and in Temperate and North 
America, this species has been found on the Mexican Andes, on the barren grounds bordering the Polar Sea, and 
also in the Arctic Islands.
