sub-opposite pairs ; lower ones with half-inch petiole ; upper 
more shortly stalked, all sharply toothed throughout, six 
inches long, one to one and a half inches broad at the base, 
and for three inches, then tapering to a rather elongated 
sharp point. Base on the upper side at a right angle to the 
pinna mid-rib, and slightly decurrent; lower base very oblique. 
Sori linear, three-quarter inch long, reaching from near the 
mid-rib to near the edge, and sometimes shorter ones between 
and rather nearer the edge. Veins mostly forked, with the 
sori on the upper line, the other barren, or with short sori
