Ferns of British India and Ceylon. 127 



GENUS XXXIV.— PLAGIOGYRIA. (Kunze.) 



(Flagios, oblique ; gyros, a circle ; the oblique ring of the capsule.) 



As in Lomaria, except that the capsules have an oblique ring, 

 and the base of the stipe is suddenly dilated, fleshy, triquetrous, and 

 furnished with large spongy glands. 



1. Plagiogyria adnata. (Illume.) Caudex stout short; stipes 

 crespitose, elongated, brown, triquetrous; a span to i\ foot long; 

 slender, naked at the base, dilated and subcarnose, furnished with 

 orbicular spongy glands; fronds a foot and more long, ovate-lanceolate, 

 chartaceous-membranaceous, sterile ones pinnatifid almost to the 

 rachis, below pinnated, but all the pinna? united by a narrow wing; 

 segments mostly opposite distant lanceolate, much acuminated, more or 

 less falcate, the inferior base round, superior base extended upwards, 

 the margins entire or obscurely toothed, the apex strongly serrated ; 

 fertile fronds pinnated; pinna? alternate distant linear sessile, rather 

 obtuse; sori covering the whole under side between the costa and the 

 brown membranaceous very distinct involucre. Bl. En. Fil. Jav. p.

Khasya, 4,000-5,000 feet elevation. 



(Also in Japan and Java.) Mr. Clarke thinks it possible that this 

 is not the same as Blume's Java plant, as the only example of that is 

 a portion of a fertile frond. 



2. Plagiogyria glauca. (Bl.) Caudex stout erect ; stipes elon- 

 gated, subcompressed tetragonous with two furrows in front, the base 

 dilated triquetrous on the anterior face bearing spongy depressed 

 glands, fronds ovate-oblong 1-2 feet long, pinnated ; sterile pinnae 

 numerous, 3-5 inches long, chartaceous, horizontally spreading, 

 sessile, or very nearly so, lanceolate, acuminated at the base, trun- 

 cated beneath, having a gland as much attached to the rachis as to 

 the very short pctio'e ; the margins finely dentate-serrulate, rather
