7. Pleopeltis tridactyla. (Wall.) Aquatic, caudex creeping, branched, the young apices only paleaceous with blackish lanccolato- 
subulate scales, stipites more or less apart, 1-3-4 inches to 1 foot long, winged upwards, and as well as the back of the costa and costule.s 
furfuraceo-squamose, fronds 2-3-9 inches long, f-lj and 2 inches wide, firm membranaceous very dark, dirty green (when dry often 
black) lanceolate acuminate entire, (rarely sub-liastato, tri-lobate or tri-partite, or 5 fido-pinnatifid) below long-tapering into a gradually 
decurrent wing upon the petiole, glabrous above, margin entire, venation very conspicuous, costules prominent beneath, rather wide apart, 
extending about two-thirds of the way to the margin, then uniting and forming large costal areoles, within which the sori have their 
origin, a second series of smaller areoles is formed nearer the margin, and these and the rest of the frond are filled up with a net-work of 
smaller irregular areoles including free simple or forked veinlets which have clavate apices, sori small not very numerous, 1-3 in each, 
large areole compital upon the secondary veins of the primaiy areole, often confluent into transverse, oblong or linear (grammitoid) sori.

(I have never seen the fronds tri-partite or pinnatifid in any of the Southern Indian or Ceylon specimens).

valley (Coimbatore hills),

8. Pleopieltis Wightiana. (Wallich.) Caudex creeping, blackish, paleaceous with rather dirty-brown ovato-lanceolate scales, 
stipites sub-aggregated a few lines to 1-2 inches long, fronds extremely variable in size and texture, from 3-4 inches to 1^ foot, and from 
I of an inch to nearly 2 inches wide, lanceolate or linear-lanceolate coriaceous and opaque, or coriaceo-membranaceous or quite membrana- 
ceous, bluntly or sharply acuminated, much and gradually attenuated, at the sometimes quite sessile base, the margin entire or subsinuate : 
venation reticulated with free included veinlets, but there are primary veins which form large costal areoles including the lesser ones 
and numeifous forked free veinlets and the compital sori, sori often much sunk (with protuberances at the back) forming a single series 
nearer the costa than the margin varying much in size, when young wholly or partially covered with very compact peltate long- stalked 
scales which are soon deciduous, then the sori becomes very large and pulvinate. Hook. Sp. Fil. v, 57; — Wall, Cat. n, 2,222 ; — Polypo-

9. Pleopeltis lepidota. (Willd.) Caudex long-creeping, paleaceous with lanceolate ferruginous scales, stipites remote, 1-2-4 
inches long, fronds coriaceo-carnose, 3-9 inches long, ^ to | inch wide, lanceolate more or less acuminate, long and gradually attenuated at 
the base above, sparingly beneath, copiously furnished with orbicular ovate, small appressed peltate scales dark in the centre, pale in the 
circumference and denticulate veins immersed indistinct, the primary veins form largo obliquely elongated areoles, which include very 
irregular and different -sized areoles and a few free veinlets which are rarely forked, sori generally very large and often exceedingly pro- 
miiient, pulvinate globose or oval, stalked scales mixed with the spore cases. Hook. Sj^. Fil. v, 56 ;— Willd. in Sc/decht Adunbr., p. 17,
