POPULAR MISCELLANY. 



Origin of Greenland A r egetation. Some 

 interesting conclusions are drawn by Mr. 

 Clement Reid from a comparison of the 

 views of Prof. Warming and Prof. Nathorst 

 concerning the origin of the flora of Green- 

 land. Prof. Warming fixes the boundary 

 between the European and American prov- 

 inces of the arctic flora as in Denmark 

 Strait, and not in Davis Strait, as botanists 

 have generally placed it. The flowering 

 plants of Greenland include three hundred 

 and eighty-six species, none of which are 

 confined to that country. Of these, exclud- 

 ing the circumpolar forms, Prof. Warming 

 finds in the list thirty-six characteristic 

 Western against forty-two Eastern species ; 

 but suggests that as the flora of arctic Ameri- 

 ca is better known, the balance will prob- 

 ably be in favor of the Western forms. He, 

 however, includes among the Eastern plants 

 only those now living in Europe, while he 

 classes the Asiatic-American species as 

 Western. Prof. Nathorst reviews these con- 

 clusions on the basis of a map of the local 

 distribution of Eastern and Western forms in 

 Greenland. He thus finds that the coast 

 nearest to Iceland contains European forms 

 alone, the southern coast contains European 

 forms in a majority, and that part of the west 

 coast nearest to America yields principally 

 Western species ; but taking Greenland as a 

 whole the flora is more European than 

 American. He also finds that the Ameri- 

 can element of the flora of Greenland is not 

 entirely cut off by the Denmark Strait, but 

 extends eastward as far as Iceland. Prof. 

 Warming believes that the nucleus of the 

 present flora of Greenland represents part 

 of the original flora which was able to live 

 through the Glacial epoch on the non-glaci- 

 ated areas ; but Prof. Nathorst shows that 

 the few non-glaciated mountain-tops must 

 have been far too high for any phanerogams 

 to exist on them, and all the lowlands were 

 then covered with ice and snow. Both the 

 Eastern and Western elements of the present 

 flora of Greenland must, therefore, be sup- 

 posed to have entered the country in post- 

 glacial times. The tables of distribution 

 show at what points a large number of the 

 plants entered ; they came from the nearest 

 land, whether European or American. The
