MOUSSES ET COUP D'OEIL SUR LA FLORE BRYOLOGIQUE DES 

 TERRES HAQELLANIQUES. PAR J. CARDOT. 



J. M. HoLziNGER, Winona, Minn. 

 This is one of the scientific reports published under the auspices of the 

 Belgian government on the antarctic Belgian expedition in 1897, 1898, and 

 1899, in a fine quarto work entitled, " Resultatsdu Voyage du S. Y, Belgica." 

 The author had published a " Note preliminaire " in the Revue Bryologique 

 t. 27, pp. 38-46 (1900), where he reports 26 species from the Strait of Magellan 

 and Terra del Fuego, 5 of which are new, and 26 species from the Strait of 

 Gerlache, 14 of which are new. In the final report before us both regions 

 are credited each with 30 species. The Strait of Gerlache is between 64° aod 

 65° S. Lat., and 61° and 62° W. long, and the the expedition spent in its ex- 

 ploration from Jan. 24th to Feb. 12th, 1898, making during that times 20 

 landings. 



The final report now before us covers 48 pages of printed matter, illus- 

 trated by 14 plates executed in the author's superb style. Following are the 

 25 species and varieties figured: Andrecea pycnotyla, A. pyginaea. A. de- 

 pressinervis , Cynodontiinn Fiiegianuni, Dicraninn Magellanicum. D. 

 laticostatuin, Ceratodon antarcticus, Webej'a ci'-uda inibricata, W. 7iutans 

 ^orma, Rhacomitrmm fiavescens, Orthotrichum antarciicuin, Dissodon 77iir- 

 abilis, Weber a Racovitzce, Bryum imperfectiini, B. inconnexuui, B. austro- 

 polare, B. Gerlachei. B. amblyolepis, Pseudoleskea antarctica, Polytrichuin

The printed portion of this report, covering 48 pages, falls into three 

 parts: i. A Survey of the Moss-flora of the Magellanic Lands. 2. The 

 Mosses of the Straight of Gerlache. .3. Systematic Catalogue of the Species 

 -of the Belgian Expedition. 



In the last part the author supplements by full Latin descriptions the 

 "brief characterizations in the Revue Bryologique of 1900. The second part 

 deals with the geographical affinities of this, the first considerable collection 

 of antarctic mosses, J. D. Hooker in 1843 having brought back only 3 mosses 

 from that far south latitude. These affinities are shown to be less close with 

 the mosses of the Magellanic Lands in the latitude of southern S. America, 

 than they are with the circumpolar moss flora of the northern hemisphere: 

 •as if these cold-region floras had been wedged apart, in geologic time, by the 

 intrusion of the tropical and temperate zonal floras. 



In the Magellanic Lands the author includes not only the territory of 

 Patagonia and the islands included in Terra del Fuego but also the islands 

 along the Pacific coast of S. America as far north as the Chonos Group in 

 about 42° S. lat., and the Falkland Islands in the Atlantic Ocean. The num- 

 ber of species known from these lands including those of the present report 

 is 227, four-fifths of which, curiously enough, are acrocarpous mosses. The 

 first part of the report makes a detailed analysis of the geographical affini- 

 ties, with interesting results, presenting with his discussion four lists as fol-
