nent in the younger fronds when dry)— 2-3 series of very irregnlar-shaped areoles on each side of the costa, which are empty or contain one 
or two clavate simple or forked free veinlets, sori generally covering the whole back of the linear fronds without order, the elliptic (gene- 
rally sterile) fronds are sometimes slightly contracted and fructified at the apex. Metten. Pobjp., p. 123, t. 3 and 9-10 -—Hook. Sp.

(It is very doubtful if this fern should be retained in this genus). 
Common in the lower forests of the Anamallays, Wynad, Coorg, &c., parasitic on trees.

(Polypodii Sp., .1mc<.— Phymatodis Sp., Fresl). 
Sori non-indusiate, large rotundate, or by confluence elongated, sometimes immersed : the receptacles produced on tlie points 
where several reticulated veins join, i. e., compital. Veins pinnate prominent from a central costa ; venules compoundly anastomosing 
in two or three series of irregular quadrate areoles, within the ultimate of which are produced free divaricate sterile veinlets. 
Fronds pinnatifid or pinnate, dimorphous, the sterile short sessile, querciform, strongly veined ; the fertile many times larger, 
with the segments articulated, llhizome creeping. 
1. Drijnaria quercifolia. (L.) Caudex creeping, short, stout, densely clothed with red-brown satiny lanceolato-subulate soft 
scales, fronds coriaceous or sub-coriaceous of two kinds ; sterile ones varying in size from 3-12 inches and more long and 7-8 inches wide, 
green when very young, but soon turning dark-brown, glossy, cordato-ovate variously lobato-pinnatifid, sometimes half way down to the 
costa ; fertile ones 2-3 feet long, long-petiolate broad-ovate deeply, nearly to the rachis, pinnatifid, segments 5-9 inches long, 1-1| wide 
oblong acuminate entire, venation manifest, costules distinct rather distant, united by transverse veins forming 4-6 primary soriferous 
areoles filled up with a network of small quadrangular areoles with or without free veins, sori compital small, numerous, two in each pri- 
mary areole, consequently in two series between and parallel with the costules. Hooker Sp. Fil. v, p. 96 ; — Polypodium quercifoliimi, Lin,

Sori indusiate, transverse marginal, generally on a reflexed tooth or lobule ; normally sub-orbicular, small distinct, sometimes 
contiguous and by lateral confluence elongate, the receptacles punctiform at the apex of the veins. Indusium membranaceous or formed 
of revolute portions of the slightly altered margin of the same form as the sorus. Veins simple or forked from a central costa ; venules 
free. 
Fronds usually small, pinnate variously pinnatifid or bi-tri-pinnate ; membranaceous or sub-coriaceous, sometimes pulverulent 
or densely hairy or scaly beneath. Stipes and rachis generally ebeneous. Rhizome tufted or creeping— (Moore). 
This genus differs from Pteris in the receptacle being punctiform instead of linear elongated.
