Polystichum Maximowiczii Diels and P. flagellare C. Chr. — 

 the species which are of especial character, peculiar to them- 

 selves, and are very different from any other species of 

 Polystichum. The resemblance of these handsome ferns and 

 Monachosorum is indeed very great, and I have wondered 

 if the former two may not be referred to the latter genus. 

 I shall return to this matter later on. Another interesting 

 fern to be mentioned is Cryptogramma Brunoniana Wall, which 

 resembles closely C. crispa R. Br. which is known to us from 

 Hokkaido. As to the geographical distribution of this interesting 

 fern, I shall refer to afterwards.

 questions the occurrence of this species in Argentine. 



New to the Formosan flora. Although the Botrychium is 

 quite common in the low-lands of Japan, it has never been 

 found in the plains of Formosa.
