Casspitosum, frondibus carnoso-crassis subcoriaceis biformibus 
subtus (junioribusque supra) squamis imbricatis copiosis 
aureo-nitentibus tectis interne reticulatim venosis, sterilibus 
spatbulatis integris integerrimisque costatis in stipitem 
brevem attenuatis, fertilibus longe stipitatis pinnatis, pinnis 
oblongis obtusis costatis, stipitibus aureo-squamosis.

A very beautiful and remarkable Fern, which I possess 
from two travellers, but both specimens probably gathered 
in the same locality, Chatham Island, of the Galapagos. From 
apparently a small fibrous root, many fronds arise, the whole 
underside and stipites of which are densely clothed with toothed 
lanceolate and much acuminated scales, of a glossy golden 
colour. The upper sides of the fronds have only a few scattered 
chaffy hairs. The sterile fronds are simple (undivided), but the 
fertile ones are pinnated with 5-9 rather small, oblong, obtuse, 
sessile pinnae, the underside of which is uniformly clothed with 
capsules mixed with the chaffy scales: — the venation, very 
difficult to be accurately distinguished, consists of anastomosing 
veins, which form oblong, hexagonal areoles: so that this 
would be a true Acrostichum of Presl, probably a Neurocallis 
or Cheilolepton of M. Fee (if the two genera are in any 
way really distinct) : yet having a habit very different from 
any known species of them.
