Ferns of British India and Ceylon. 325 
uniform from a central costa, venules anastomosing sometimes trans- 
versely parallel, forming parallelogrammoid areoles, with excurrent 
free or occasionally connivent or anastomosed veinlets, sometimes 
uniting in roundish or oblong hexagonal unequal oblique areoles, with 
variously directed simple or divaricately forked veinlets, the veins of 
the fertile frond when contracted less developed ; fronds simple or 
rarely lobed, rigid, coriaceous, opaque, the fertile often contracted.

wide-creeping, paleaceous with lanceolate-setaceous scales j stipes dis- 
tant, 1-2 inches long, furnished at the base with lanceolate-linear 
often hairy scales; fronds dimorphous, carnose-coriaceous, dark 
green above, but hoary with sparse stellated pubescence beneath, and 
paler and even white with more copious compact hairs ; sterile fronds, 
2-4 inches long, spathulate or elliptical-lanceolate, obtuse; fertile ones 
6-8 inches long, linear or oblong obtuse or acute, both kinds tapering 
below into the stipe, costa sub-carinate, costules sunk obscure, their 
areoles including four (sometimes only three or two) veinlets, which are 
generally free with clavate apices, though they sometimes anastomose ; 
sori deep sunk in the tomentum and in the substance of the frond on 
each side of the costa, arranged 5-6 in obliquely transverse series, 
capsules long stalked, mixed with long stalked stellated scales.
