Ferns of British India and Ceylon. 
Tidal backwaters throughout the Indian region. 
(Also throughout the world in warm countries near the sea.) 
GENUS LXXXVII.— PHOTINOPTERIS. ( J. S/;l) 
(P/iofemos, shining ; p fen's, a fern.) 
Veins copiously anastomosing, forming numerous areoles with 
free included veinlets, the primary veins costseform ; fronds pinnate, 
the upper pinnae much contracted and wholly soriferous on the under 
side ; stipe adherent to the rhizome, pinnse articulate with the rachis. 
(Very like Drynaria in its pinnae and venation, but the vernation is 
adherent not articulate.) 
1. Photinopterts rigida. {Wall.) Rhizome repent or scan- 
dent, paleaceous, with elongated brown subulate fringed scales mixed 
with hair-like ones in age, white glaucescent ; stipes short, nearly as 
thick as a writing pen ; fronds T-I-3 feet long, broad-lanceolate, very 
hard-coriaceous glossy, pinnate ; sterile pinnae long-petiolate, distant 
3-6 inches and more long, broad ovate, acuminate, the apex gene- 
rally caudate and curved upwards ; venation manifest, elevated on 
both sides, costules subflexuose, united by transverse veins into four- 
angled areoles, which are again divided into lesser areoles including 
branched free clavate veinlets ; petioles articulated on the rachis and 
dilated into a large orbicular scutiform base ; sometimes these sterile 
pinnae occupy the whole frond, more frequently the rachis is suddenly 
elongated at the apex, and bears 1-13 distant very contracted nar- 
row-linear and fertile pinnae, 5-12 inches long, soriferous except on 
the costa and on the slightly revolute margin. Wall. Cat. 71. 27.
