T^3o. THA-YEXtl^^, Copeland. 



Sori round or oblong, on much contracted higher segments of deeplj^ 

 pinnatifid or pinnate fronds. No indusium. 



Rhizome tortuose or scandent, woody. Fronds articulate at the base, 

 placed on specialized short branchlets of the rhizome, at least the barren 

 ones induplicate, or convolute at the base so as to form a humus-collecting 

 corniform sack; veins anastomosing copiously; areolae with free veinlets. 



Papua, Philippines. 



Fertile fronds stipitate, not humus-collecting at the base. 



(1) Th. nectarifera. 

 Fertile fronds sessile, humus-collecting at the base. (2) Th. cornucopia.

Rhizome stout, woody, tortuose, scaly towards the extremity, the 

 scales adpressed, orbicular, peltate. Fronds dimorphous. Barren fronds 

 (cup-leaves) sessile, ovate, pinnatifid, induplicate, the lobes oblong, obtuse. 

 Fertile fronds stipitate, oblong-lanceolate, 45—60 cm. long, simply pinnate. 

 Pinnae numerous, the lower ones adnate, lanceolate, provided beneath 

 with copious dot-like glands, the higher narrowed or contracted, linear, 

 tortuose, soriferous, with the lamina more or less cut away between the sori.

Rhizome scandent, often descendent, clothed with small, lanceolate, sub- 

 peltate, acuminate, adpressed scales. Barren fronds (cup-leaves) sessile, to 

 50 cm. long, deeply pinnatifid, convolute at the base. Fertile fronds 

 similar to the barren ones but longer, with the higher segments narrowed 

 or contracted, linear, moniliform, soriferous, with the lamina deeply incised 

 between the sori.
