12 rnOCEEDIKGS OF THE 



Isliinds. The first f^roiip he termed " Asturian," tlie second 

 "(luUicau" types. He showed that the derivalion was due to a 

 former land-connectiou, unsul)mei-ged during the Glacial Epoch. 

 Engler held that the reimiuigratiou of the Atluntic element took 

 place in post-glacial times, and Dr. Scharff dealt incidentally with 

 It in his chapter on the Lusitanian fauna published in 1899. The 

 subject assumed greater prominence at the British Association. 

 Meeting at Portsmouth in 1914, when Mr. Clement Keid gave 

 an address on the relation of the present plant population of 

 the British Isles to the Glacial Period, and contended that no 

 temperate flora could have survived the rigours of that liuie, 

 but that the present flo.a came in towards the end of that 

 period. 



Dr. Stapf showed that two classes of plants became evident as 

 the work went on ; one, such as had their Continental areas in 

 A\'estern France and the Iberian Peninsula, and the other, those 

 ranging beyond these limits over North Africa, and the Medi- 

 terranean as far as the Caucasus and Syria. The first may be 

 called "Atlantic'*' in a restricted sense, the second "Mediter- 

 ranean," both together as " Southern." The complete list was 

 drawn up by comparing the last editions of Babington's ' Manual ' 

 with Koch's ' Synopsis,' with a few necessary restrictions, but 

 excluding IJieracium, liuhns, and Rosa. In this way 1500 species 

 remained, of which 150 answered to the definition of Southern 

 elements, or about 10 per cent. These were traced in their 

 distribution, and the result recorded in the maps shown. The 

 littoral species, amounting to fully one-third of the Southern 

 elements, must affect the cartographic result ; the inland or non- 

 littoi-al Soutliern species of the British flora number 9.'3, one-half 

 following the Atlantic, and the other half the Mediterranean 

 type of distribution. 



' I\Ir. J. C. Shenstone, Prof. G. S. Boidger, Mr. John Ilopkinson, 

 and Dr. C. E. Moss discussed various points raised, and Dr. Stapf 

 replied.
