The present fern is especially interesting on account of its 

 resemblance to those peculiar Japanese ferns, which have doubt- 

 fully been referred to Polystichum. Ihty are Polystichum Ma- 

 ximowiczii Diels, and Polystichum flagellare C. Christensen. 

 The former is first established by Baker who refers it to Poly- 

 podium ; then the fern is transferred to Ptilopteris by Hance, 

 next to Phegopteris by Christ and finally to Polystichum 

 by Diels. The latter, P. flagellare, is referred to Polypodium 

 by Maximowicz, then to Phegopteris by Mr. T. Makino, after- 

 wards to Ptilopteris by the same author, and finally to Poly- 

 stichum by C. Christensen. When I examined these two 

 species, I have found that they are very peculiar and far diffe- 

 rent from any species belonging to Polypodium, Phegopteris, 

 or Polystichum,. but very like to Monachosorum in its habit,
