Ferns of British India and Ceylon. 343 
size from 3-12 inches and more long, and 7-8 inches wide, green

variously lobate-pinnatifid, sometimes half-way down to the costa; fertile 
ones 2-3 feet long,long-petiolate broad-ovate deeply nearly to therachis 
pinnatifid, segments 5-9 inches long, inch wide, oblong acuminate, 
entire ; venation manifest, costules distinct rather distant, united by 
transverse veins forming 4-6 primary soriferous areoles filled up with a 
net-work of small quadrangular areoles with or without free veins ; sori 
compital small, numerous, two in each primary areole, consequently in 
two series between and parallel 
with the costules. Polypodium
