above with a few subulate scales on the rachis of the pinnae, and with 
hairs on the rachis of the segments, ternately divided, or subpedately

petiolate or subsessile lanceolate acuminate, deeply pinnatifid to 
the apex, or with the apex long caudate, segments oblong obtuse 
subtruncate, serrated at the sterile portions of the apex ; sori lateral 
on the segments, never extending to the apex or base ; veins rather
