Very near D. Sieboldii, but differs from it by the arrangement of sori 

 wliich are scattered towards the margin, but not along the costa. It is still 

 nearer to D. podopliylla (Nat. Pfl.-fam. Pterid. p. 169 fig. 91, C et A), but 

 distinguishable from it by the acutely serrulate margin of the fronds, by the 

 subentire indusiura and in the venation.
