Late events have contributed to the opening up to us of 

 the Botany of N. China and Japan, whose geographical 

 position naturally led us to expect European forms of Ferns. 

 The present species was at first considered by me to be a 

 state of Aspl. lanceolatum, while Mr. Eaton looked upon it 

 as more related to Aspl. fontanum. More copious specimens 

 have satisfied me it is truly distinct from both. The young 

 fronds are simply and closely pinnated, with obliquelv ovate 

 pinnae.
