coloured scales like the base of the stipes. Stipes caespitose, + 20 c.M. 

 long, slender, the base nigrescent-stramineous, the upper part naked, greenish 

 like the main rachis. Fronds 20 — 25 c.M. long, 10 — 13 c.M. broad, acumi- 

 nate, 3-pinnate. Pinnae lanceolate-ovate, short-stalked, often acute. Pinnulae 

 oblong, obtuse, the rachis narrowly winged. Tertiary segments oblong, ad-

 the lower incised and toothed, the others toothed or serrate. Texture 

 herbaceous, rather flaccid; surfaces naked. Sori oblong, more or less curved,

 apart. Texture somewhat firmer.
