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

 which are restricted to tiie 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, hy far, the more prominent part. It contains many interesting species, sucii 

 as Frilillaria kamtschatcenfiis, Bosclmiakia glabra. Rhododendron chrysanthum and Tcamlscltuti- 

 ciim, Viola Langsdorffii, Claytonia sarmentosa, Lupinus JVootkalensis, Epilobium Behringianum 

 and E. Bongardi, Primida cuneifolia, Geniiana auriculala, Casniope lycopodioides, Erigeron salsu- 

 ginosus, Lysidiilon Icamtschalicum, Saxifraga reflexa, etc. The Europeo-Asiatic elements are also 

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

 form al)out twenty-four per cent of the whole. 



In the Kuriie 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, Telrapoma, 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 nesv to .lapan ; and 12 species are represented under difierent 

 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 Prnnus Ceraseidos, var. hnrilensis, Saxifraga hroncJiialis, Ar- 

 temisia laciniala, Artemisia sericea, Carex inacilenta and Carex vaginala, the remaining 60 plants 

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

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