220 Ferns of British India and Ceylon. 
phous, the fertile much contracted, pinnatifid down to a broadly 
winged rachis into 3-4 pair of pinnae or lobes on each side, 6-12 
inches long, 1-2 J inches broad, lowest pair often bifurcate, margins 
quite entire in the sterile, more or less crenated in the fertile, sub- 
coriaceous, glabrous on both sides ; main veins distinct nearly to 
the margin, with cross veins forming series of large areoles in which 
are included netted veinlets and simple or forked free veinlets ; sori 
large, generally in two pretty regular series between the main veinlets, 
nearly always at the apex of the free veinlets, often continued all 
down the wing of the stipes ; indusium generally more or less reni- 
form, sometimes elongated and irregular. Presl. Rel. Hcenck^ 28.

more long, with many scales close to the base ; fronds very variable 
in size, from 8 inches up to several feet, deltoid in outline, apex 
pinnatifid, below which are 1-4 pair of pinnae, which are either only 
lobed or completely pinnated with the secondary pinnae deeply pin- 
natifid, or even again pinnated {i.e. tripinnate), with the tertiary 
pinnae deeply pinnatifid (quadripinnatifid), the lowest pair of pinnae 
are always deeply pinnatifid or pinnate on the lower margin, but the 
other pairs are generally much less so and often only lobed down, 
texture thin, surfaces glabrous in some vaiieties, but in others hairy 
on the upper surface and puberulous on the costas and costules
