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 Pliegopteridece, differing only in the venation and sori 
being more decidedly reticulated. The name is derived from 
dictyon, a net, cline, a bed, in allusion to the reticulated fructi- 
fication.
