pale brown or stramineous; the rhachis mostly proliferous near the apex 
with 1—3 gemmae. Frond deticcerois membranous or flaccid, open, ovate 
to ovate- -oblong, 11/2—2 ft. long 0—16‘ broad at the base, pinnate, 
with pinnatifid apex, the lowest si neither shorter nor more distant 
than those next above. Pinnae mostly opposite in 14—18 pairs, spreading, 
the lowest 6—9‘ long, shortly stipitate (°/4' or less), often broadest near 
the middle (1—13/<‘), cut to near the costa into oblong, obtuse or subfalcate, 
subentire or sinuato-dentate lobes or segments which are 2—4” broad 
and separated by broad rounded sinuses. Nervatio Pecopteridis. Veins 
excurrent, pinnate with simple veinlets at angles of 30—40° (their costule 
at 60—70°), in 6-—-9 pairs. Sori short, 1’ or less, straight asplenoid on 
ei marginal half of the veinlet and generally, but not always, touching 
e edge, the first anterior often diplazoid, rarely uncinate or didymo-

even running down the opposite side also, didymochlaencia. Invol. in all
