 angula laeve. 



In sylva, cum Thea. Kujoodoo versus, Tingree Feb. 1836. 



The metamorphosis of the fronds is very evident in the 

 composite axis of the fructification : the nature of the thecae 

 is very distinct, almost enough to warrant the total separa- 

 tion of the tribe from Filices ? It. Ass. 405.

Epiphytica in arboribus, surculis brevissimis dense paleaceis, 

 frondibus simplicibus lanceolato ensiformibus, integris, acumi- 

 natis carnosis, tactu mollibus, in stipitem complanato ancipito-

Venatio. Vena primaria frondis basin versus tantum sub- 

 distincta, caeterum frons occupata est, venulis anastomosanti- 

 bus reticulas irregulares oblongas formantibus. 



Sori lineares continui vel interrupti his impositi, rarius ve- 

 nulas connectentis occupantes, depresso parenchymate fron- 

 dis nempe utrinque venarum soriferarum elevato. 



In arboribus Cheikwar, Feb. 8, 1836. 



The venation of this genus may in one view be compared 

 to that of Vittaria, that is as consisting of a central vein, and 

 many secondary ones running very obliquely, these being con- 

 nected by branches, running either transversely, or downwards.
