The table shows at once the great preponderance of the Asiatic species, the greater portion of 

 which are i-estricted to the eastern and northeastern parts of Asia. Next in importance come the 

 Americo-Asiatic, which divide themselves into two distinct groups : the American and north Pacific. 

 The latter constitutes, by far, the more prominent part. It contains many interesting species, such 

 as Fritillaria kamtschatcensis, Boschniakia glabra, Rhododendron chrysanthum and kamtschati- 

 cum, Viola Langsdorffii, Olaytouia sarmeidosa, Lupinus JVbotkatensis, Epilobium Behringianum 

 and E. Bongardi, Primula cuneifolia, Gentiana auricidata, Oassiope lycopodioides, Erigeron salsu- 

 ginosus, Lysichilon kamtschaticum, Saxifraga reflexa, etc. The Europeo-Asiatic elements are also 

 liberally represented. If the species which extend into northwestern America are included, they 

 form about twenty-four per cent of the whole. 



In the Kurile flora we have no additions of orders to make to the rich flora of Japan. As to 

 the genera, there are six new additions, namely, Parrya, Tetrapoma, Claytonia, Lupinus, Arme- 

 ria and Dodecatheon. These genera are found only in the northern Kuriles. None of them occur 

 in the island of Saghalin. 



As to the species, 54 are entirely new to Japan ; and 12 species are represented under different 

 varieties chiefly in the alpine regions of the main island. Of these, 13 are circumpolar species; 2 

 species and 1 variety are endemic ( ?) ; 5 species are Europeo-Asiatic, three of which extend into 

 northwestern America; 6 are northern Asiatic; 17, northeastern Asiatic; 18, northern Pacific, and 

 4, American. With the exception of Prun.us Ceraseidos, var. kurilensis, Saxifraga bronchialis , Ar- 

 temisia laciniata, Artemisia sericea, (Jarex macilenta and Carex vaginata, the remaining 60 plants 

 have thus far been found only in the islands lying northward of Urup ! These facts clearly indicate 

 that the vegetation of the southern Kuriles is very much like that of Japan (northern), while tha
