i Whether this new fern and its allied 

 species should be referred to Alliyrium 

 or Diplazium, is very ^questionable. The 

 habit of these J ferns is rather of the 

 Athi/riwm-type, but; the sori are some- 

 times of the Diplaziitm-iype. Very 

 remarkable for its having very long 

 slender tails at the apex of the pinna;.
