2. District of South Georgia and the South Sandwich Islands.
For information on the climate and vegetation of South Georgia
I need only refer to a previous article (35). South Georgia has,
as seen before, also constituted a province together with the
Falklands. If we only look at the flowering plants, this might be
explainable, for they are all common to the Fuegian district (53).
But we must also pay some attention to other groups, and then
we shall see that endemismus occurs in a very high degree. Of
my collections the liverworts are described (40): distinct relations
are shown to both antarctic and other subantarctic lands, but Mr.
Stephani added not less than four new species, and all the
liverworts known are not twenty. The first news I have received about
my mosses is that Mr. Cardot has described two new South-Georgian
genera, of which one is a quite new type of moss (9); he has
told me in a second letter, that of 78 species collected by me 38
are endemic, 34 are also found in the Magellan territories, 14 on
Kerguelen, 14 in the New-Zealand district, 6 in the Antarctic and
7 in the boreal zone. The marine algæ described by Reinsch
contained 66 % of endemic species. To this fact I may add that a
fugitive glance at my collections has led me to believe that there
is a remarkable affinity between South-Georgian and antarctic algæ.
The South Sandwich Islands, no doubt, form a still more distinct
transition to the Antarctic than South Georgia. No scientist has
ever visited them. Forster saw them from a short distance and
relates of them (19, p. 420): »Ueberhaupt hatte das ganze Land
den ödesten, schreckenvollsten Anblick, den man sich nur denken
kann. Nicht eine Spur von Grün, ja nicht einmal die unförmlichen
Amphibien [1], die wir auf Neu-Georgien gesehen hatten, waren
hier zu sehen.»
3. District of Kerguelen.
Includes, besides Kerguelen Island, the Marion, Prince Edward’s,
Crozet’s, Macdonald and Heard Islands.
