the rachis flexuose, margined, like tlie costae and costulae densely 

 ferrugineo-hirsute. Pinnae numerous, ascending, petiolulate, trapezoid- 

 oblong, ± 15 mm. long by 6 — 7 mm. broad, obtuse, deeply incised into 

 linear or cuneate, simple or 1 — 2-partite segments, the lower segments 

 decurrent upon the petiole; lobules to 2 — 3 mm. long by nearly 

 1 mm. broad, toothed, acuminate from the base. Testure membranaceous ; 

 colour yellowish when dry; surfaces long-hairy, the hairs ferrugineous. 

 Sori solitary in the axils of the pinnae; indusium obconical, 2- 

 valved to 'j^ — Va'^^s-y down, densely ^hirsute, the valves rounded, 

 long-ciliate.

Rhizome creeping, filiform, sparingly hairy. Stipes filiform, + 2'/i — 3 

 cm. long, brown, sparingly hairy. Fronds elongate-oblong, ± 5 — 6 cm. 

 long, I'/i — 2'/i cm. broad, 2-pinnatifid, obtuse, somewhat narrowed at 

 the base, the rachis very narrowly winged, provided with short, scattered,

 acutely toothed. Texture membranaceous; colour brown when dry. Sori 

 terminal on slightly narrowed segments, in the uppermost part of the 

 frond; indusium obconical at the base, 2-valved, the valves subtriangular,
