January, 1939 
pressed to the midrib; lowest seg- 
ments smaller, sometimes free; 
lateral veinlets numerous, very 
fine, less than 1 mm. apart at the 
margin 
Sori more distant from the midrib, in 
one or two rows on each side, 
sometimes confluent covering the 
whole under surface; lateral vein- 
lets rather distant. 
Fronds all similar, broadest in the 
middle, the segments all adnate 
to the rhachis, the lowest much 
reduced, or rarely a large free 
pair of pinnae at the base; sori 
distinct. 
Fronds broadly elliptic, up to 45 
cm. long and 8 cm. or more 
broad; apex not elongated .... 
Fronds linear-oblong, 2.5-2.75 
cm. broad; apex elongated 
Fronds more or less linear, 2-5 cm. 
broad, the fertile, segments more 
distant, narrower; lowest pair 
often free and abruptly elongated; 
sori confluent 
Fronds pinnate at least in the lower part, 
the pinnae distinct; sometimes the 
upper part undivided. 
Fronds undivided for the most part, 
with a few short broad pinnae 
below 
Fronds divided for the most part, but 
frequently with a long terminal 
segment. 
Plants small and decumbent or sub- 
decumbent; fronds pinnate be- 
low the middle, narrow-linear, 
texture membranous to sub- 
coriaceous. 
Sori close but distinct. 
Fronds about 3 cm. broad, 
subdimorphic; sterile fronds 
broader than the fertile . . 
Sori confluent, covering the 
under surface Lomaria-like. 
Fronds very dimorphic, 1-2 
cm. broad, the sterile ones 
very short and subdecum- 
bent, fertile ones twice as 
long, erect 
Fronds subdimorphic, the fer- 
tile ones somewhat longer 
than the sterile
