INSULAR FLORAS. 35 



the essentially Asiatic Luchu Archipelago, to the south 

 of Japan, and the Kurile chain in the north, connecting 

 Yesso with Kamtschatka. 1 The list of vascular plants 

 collected in Sulphur Island numbers twenty-seven, includ- 

 ing five ferns and one epiphytic orchid, Luisia teres. Seve- 

 ral of the plants are identified with Japanese species, and, 

 with one exception, the rest are common littoral plants 

 of the Pacific, or of wider range. The exception is

 South Africa and Bourbon Island. We suspect that it

 cal D. viscosa, rather than this comparatively local 

 species. 



Ceylon is so near the mainland of India, with which

 sense of the word ; yet, for many reasons, it claims a 

 mention here, and more particularly on account of the 

 important recent literature.' 2 Ceylon is so well situated, 

 so easy of access, its flora so rich, its climate so good, 

 and its botanic garden so well adapted for scientific work, 

 that it is to be hoped that the laboratory which has been
