Obs. — The present- genus was founded by Mr. Moore upon 

 a pinnate fronded fern from Assam, and placed by him, on 

 account of its sori being reticulated, next to Hemionitis, under 

 which genus it is also placed in the " Species Filicum;" but it 

 possesses no other point of affinity with Hemionitis, its whole 

 habit and nature of venation agreeing with the meniscioid 

 group of Phegopterideoe, differing only in the venation and sori 

 bring more decidedly reticulated. The name is derived from 

 dictyon, a net, elin?, a bed, in allusion to the reticulated fructi- 

 fication.
