young. Stipes S— 15 c.M. long, naked. Fronds IS'/j— 4S c.M. long, 10—30 

 C.M, broad, deltoid to lanceolate-triangular, 3 — 4-pinnatifid. Pinnae lanceolate, 

 the lower deltoid, produced on the lower side. Pinnulae lanceolate-deltoid, 

 subsessile, obliquely cuneate at the base. Segments oblong, cuneate at the 

 base, deeply pinnatifid with erecto-patent, ligulate, simple or 2-fid lobes 5 — b 

 m.M. long, 1—2 m.M. broad, those of the fertile fronds oblong, '/j na.M. broad 

 at the base, with a suddenly dilated, cuneate, soriferous apex. Texture + 

 coriaceous; surfaces naked. Sori numerous, 1 to each ultimate lobe, com- 

 monly with 1 — 2 horns beyond; indusium nearly 2 X *s long as broad,

Rhizome creeping, densely fibrillose. Stipes 15 — 23 c.M. long, erect, 

 strong. Fronds 50 — 45 c.M. long, 15 — ^30 c.M. broad, deltoid, 4-pinnatifid. 

 Pinnulae of the lower pinnae deltoid-lanceolate, the lobes of the tertiary seg- 

 ments cut down nearly to the rachis into narrow, linear laciniae. Texture 

 coriaceous. Sori semicylindrical, on the dilated apices of the laciniae, with-, 

 OHt horns; indusium long, 5 — 4 X sis long as broad.

Sori roundish or oblong, submarginal, solitary and terminal on the veins. 

 Indusium half-cupshaped or semicylindrical, attached at the base and sides, 

 open at the outer edge. Receptacle distinct. 



Rhizome creeping, hairy or fibrillose. Stipes 2-seriate, adherent. to the 

 rhizome. Fronds variously divided; ultimate free divisions rhomboidal-oblong 

 or linear-triangular, broadest ± at the base, the upper base rather broadly 

 and the lower rather narrowly cuneate; veins free, simple or- branched.

 as a section of Dennstaedltla (Philipp. Journ., II, 126).
