size from 3-12 inches and more long, and 7-8 inches wide, green 

 when very young, but soon turning dark-brown, glossy, cordate-ovate 

 variously lobate-pinnatifid, sometimes half-way down to thecosta; fertile 

 ones 2-3 feet long, long-petiolate broad-ovate deeply nearly to therachis 

 pinnatifid, segments 5-9 inches long, i-i| 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
