Rhizome creeping ; scales dense, brown, linear-lanceolate, the margin beset 

 with sharp, short, spreading, subremote teeth. Fronds 45 — 55 c.M. long, + 

 1.T c.M. broad, broadest + '/j of the way down to the base; upper half 

 obovate, short-acurainale at the point, narrowing gradually below into the 

 linear-cuneate lower half and the short slipe. Texture coriaceous; surfaces 

 naked; the lowest part with a distinct, black, but not prominent midrib; 

 central areolae 1—5 c.M. long, + 4 m.M. broad. Sori long, very numerous, 

 often joining, deeply sunk ; edges of the furrows not raised ; paraphyses linear-

Sori linear-oblong or linear, ff^rming an acute angle with the costa, 

 rarely subparallel to it ; receptacle crossing the areolae. No indusium.
