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 dilate i, fleshy, triquetrous, and 
furnished with large spongy glands. 
1. Plagiogyria adnata. {Blume.) Caudex stout short; stipes 
caespitose, elongated, brown, triquetrous; a span 'to 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 pinnae united by a narrow wing; 
segnaents mostly opposite distant lanceolate, much acuminated, more or 
less falcate, the inferior base round, superior base extended upwards, 
the margins entire or obscurely tootlied, the apex strongly serrated ; 
fertile fronds pinnated; pinnae 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 poss'blethat 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, acuninated at the base, trun- 
cated beneath, having a gland as much attached to the rachis as to 
the very short petiole ; the margins finely dentate-serrulate, rather
