83. P. (Eupolypodium) papillosum, Bl. ; caudex creeping 

 paleaceous with brown subulate scales, stipites 6 inches to a

 glabrous brown glossy, fronds a span to a foot and more long 

 2 inches wide membranaceous subpellucid dark-green elon-

 tenuated at the base deeply almost quite to the base pectinato- 

 pinnatifid glabrous, segments linear-oblong obtuse exactly 

 horizontal obscurely serrated only at the apex, veins mani- 

 fest distant erecto-patent forked, branches spreading, supe- 

 rior one bearing the sorus nearer the margin than the costule 

 sunk in a very deep cavity or sack forming a very elevated 

 papilla on thS upper side. — Bl. Fil. Jav. p. 191. t. 88. Br. in

Hab. Bourbon, Bory, Cannichael.—My only specimens of this apparently rar

 a foot long l|-2 inches wide coriaceous (pendulous ?) elon-' 

 gato-oblong acuminate cuneate at the base, of the same co- 

 lour on both sides (destitute of white cereaceous matter) 

 deeply pinnatifid to within 1-2 lines of the base, segments
