Veiy near D. Sieholdn, but diifers from it by the airangement of sori 

 wliich are scattered towards the raargin, but not aloug the costa. It is still 

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

 distinguishable from it by the acutely seri-ulate margin of the fronds, by the 

 sulientire indusium aud iu the venation.
