soris copiosis, involucro demum hemispherico amplo.

This again is a Fern, with as much claim to be placed in 
Hemitelia as in Cyathea. Could we see the involucre in its 
young state, we should probably find it covering the whole 
sorus with a globose membrane: but, in a more advanced stage, 
it is quite open on the outer or upper side, towards the margin 
of the segment ; but still covering the sorus like a hood. We 
shall have occasion to observe a similar structure in the Ceylon 
Cyathea Walkere. —(See our Tan. DCXLVII.)
