seven volumes have appeared. The expedition was under the direction of 
Dr. Otto Nordenskjold, and extended over the years 1901 to 1903. The 
Antarctic , the vessel that carried the expedition, was shipwrecked, resulting 
in the loss of a good share of the collections, including part of the mosses. 
From the material saved the author determined not less than 201 species, of 
which 137 belong to the Magellanic Region including the Fuegian Archi- 
pelago and the Falkland Islands; 80 belong to South Georgia, and 23 to the 
Antarctic Region proper. Of this number 65 species are new to science, four 
of these serving as the types of new genera. Mr. Carl Skottsberg, the botan- 
ist of the expedition, is honored for his courage and perseverance by having 
dedicated to him one of these genera, Skottsbergia paradoxa, a most curious 
dicranaceous moss with asymmetric peristome. 
The work 0.0 vers 298 pages, accompanied by eleven plates superbly exe. 
cuted by the author himself, who shows here again, as in all his publications,, 
the artist as well as the scientist, both of the first order. These plates illus- 
trate fourteen of the hew species, namely; Andreaea verrnculosa, A. 
pumila t A . heterophylla, Skottsbergia paradoxa , Verrucidens turpis , 
Pseudodistichium austrogeorgicum, Grimmia antarctici* Orthotrichum vit- 
talum, Tayloria Dubyi, Bryum cep ha lozioides , Exodokidium subsymmetri- 
cum, Bartramia leucocolea, Conostomum perangulatum and Breutelia 
Skottsbergii. 
In addition 61 figures are printed in the text, which falls into three parts; 
First. La Flore Bryologique des Terres Magellaniques, pp. 4-187, estab- 
lishing 243 endemic species out of 444 now known. 
Second. La Flore Bryologique de la Georgie du Sud, pp. 188-240, show- 
ing 42 endemic species out of 93 known. 
Third. La Flore Bryologique de l’Antarctide, pp. 241-282, with 24 
endemic species out of 47 known. 
By his keen analytic method, the author compares what is known of 
each flora, not only’ from the Swedish expedition, but from all prevous 
sources of information, with the adjacent floras here discussed, as well as 
with those of Tasmania, New Zealand, Northeastern Asia and our arctic 
region. After the critical chapters, there follow, in each case, systematic 
l[sts of the regions discussed. 
To enter into the details of the findings in their critical comparisons is 
not possible in a short review. Suffice it here to state that the author shows 
conclusively that the Magellanic moss flora shows closer affinity to the Aus- 
tralian moss-flora than to that of Patagonia. And the intervening groups 
of islands, of Falkland, South Georgia, Kerguelan Land, together with the 
Auckland and New Zealand groups, are probable the highest outcroppings 
above the ocean surface of once continuous or nearly continuous land- 
mass. In summing up the problems presented in the moss flora of the 
Antarctic continent, Mr. Cardot closes thus : 
“ What are the origins of this flora? The question touches closely on the 
problems of the origins of the South Continental flora. Should one recognize 
in the present Antarctic flora a direct or actual picture, weakened to be sure.
