ZXX. OENEEA OF PEEKS: 



piferous one two deeper furrows in which the sori lie. Bhizome 

 creeping, ecalj, — Totally distinct from the Gymmogrammea, and, 

 as it appears to us, from all the established genera of ferns. 

 Ex. : O. pentagonus (Grammitis bieulcata. Hook,) 



(b) Veins imiform reticulated, withont free included veinlett.

Sori non-indusiate, linear, continuftus or interrupted; the 

 receptacles sub-marginal or medial, superficial or somewhat im- 

 mersed. Veins uniform reticulated, forming elongated longitu- 

 dinal or oblique areoles, without included free veinlefs. 



Fronds simple lobate or pinnate, rigid ; the sori and costa in 



T. niphoholoides, clothed with stellate hairs. Rhizome creeping.

Sori non-indusiate, linear, continuous j the receptacles sub- 

 marginal, immersed ; the interior thickened margin of the groove 

 elevated and sub-indusiform. Veins uniform reticulated; the 

 venules anastomosing in unequal elongated oblique areoles, with- 

 out included free veinlets. 



Pronds polymorphous, simple or lobed, coriaceous ; the fertile 

 more or less contracted. Bhizome creeping. — ^A well-marked 

 genus, differing from Schizoloma in the absence of an induaium, 

 and from Z>»yB»ojfo«siHB in the" absence of free included veinlets.
