Linnseus gives “Siberia” as a locality for the N. American 
Asplenium (Camptosorus) rhiaophyllu.m. The Siberian plant is 
however since acknowledged to be a new species, distinguished 
by the entire absence of lobes or auricles at the base of the 
frond, which are so characteristic of the United States. But 
even in Siberia the present species appears to be of very rare 
occurrence,, insomuch that the late learned author of the 
Ilora Rossica (Ledebour) was obliged to declare “species 
mihi ignota.” Only two stations for it have been yet re- 
corded in all the Russian dominions; and now that it has 
been detected in the island of Tsus Sima, off the coast of 
Korea, the discoverer there accompanies his specimen by the 
remark “ the only specimen found and that is the one here 
represented. 
Camptosorus and Antigramme only differ from Scolopen- 
pendrium by the partial anastomosing of the veins ; in the 
former next the costa ; in the latter next the margin. To me 
it seems most natural to unite both with Scolopendrium.
