Rhizome creeping, densely black-hairy. Stipes + 3 — 4 cm. long, 

 narrowly winged in the upper half. Fronds deltoid-ovate, + 5 — 6 cni. 

 long by 3 — 4 cm. broad; main rachis narrowly winged. Pinnae sub- 

 horizontal, oblong, cut down to a winged rachis; lowest pinnulae again 

 deeply pinnatifid with linear, simple or forked segments to 6 mm long 

 and ± ',,, — 1 mm. broad, blunt and rounded or emarginate at the apes, 

 provided with many oblique or sublongitudinal, flexuose or nearly straight 

 spurious veinlets between the margin and the simple costa. Texture 

 membranaceous; edges slightly but distinctly crisped; surfaces naked. 

 Sori terminal on abbreviated segments, the indusium narrowly winged, 

 acute at the base, 2-valved 'l.,-waj down; valves bluntish or rounded.

EMzome creeping, black, capillary, short-tomentose. Stipes scattered 

 but subcaespitose, + I'/, cm. long, capillary, black, naked, as is the 

 whole plant. Fronds triangular, ± 2 cm. long, broadest at the base, 

 cut down to a broad wing to the rachis into 6 pinnae. Highest pinnae 

 shortest, 2 — 3-fid at the apes, lower opposite, to 1 ' , cm. long, and 5 

 mm. broad at the base, deeply incised with 5 lobes on each side, which 

 are partly incised again. Ultimate segments obtuse, rarely acute, + 2 

 mm. long, 1 mm. broad. Testure thin; colour pale-green; a single 

 central vein in each lobe, reaching the apes. Sori axillary, on the 

 anterior side of the pinnae, ± 3 on a side ; indusium oblong-campanulate,
