(Ugena, Cavanillex ; Hydroglos.sum, WiUdenow in jmrt ; Gisopteris, Bernhardi ; Odontopteris, Bernhardi ; Cteisium, 
chaux ; Anthrolygodes, Presl ; Ramondia, J//r6e^; Vallifilix, Tlionars ; Ophioglossi, Sp. ; Auctorum). 
Fructifications forming compressed distichous spikelets, exserted on the marginal teeth. /Sy)0?'e-cases included beneath ovate 
cucullate, imbricated, persistent, scariose, bractiform indusia, solitary on the anterior side of the venules, attached sideways, oval, resu- 
pinate, sessile, or very shortly pedicellate, having a many-rayed apical ring, Ydm forked, often repeatedly, from a central costa ; venules 
free ; in the fertile spikelets pinnate, the velnlets sporangifcrous on the anterior side. 
Fronds branched, the rachis scandent ; the branches usually conjugate, variously digitato — or palmato-partite or pinnatifid, or 
pinnate, the pinnas sometimes articulated and deciduous, — Rhizome csespitose or creeping. — Scandent ferns (Moore.) 
1. L'jyodiwn Scandens (Sw.) Stems rather slender, climbing to a considerable extent, glabrous, or slightly pubescent, pair of 
fronds petiolate, each pair pinnate, pinnules 8-10 from ovate-cordate to oblong-lanceolate or hastate, h to Ih inch long, often shortly lobed 
at the base, articulate on a slight thickening of the apex of flie petiole, sori short, protruding from the margin of segments usually shorter 
and broader than the barren ones. (Bentham), Lygodium Salicifoliura, Fresl. /—Lygodium microphyllum. Br. 2>rod. 1, 162. 
Wynad — very abundant. 
PLATE No. LXL 
2. Lygodium dichotomum (Sw.) Stems climbing and as well as the fronds, perfectly glabrous, pair of fronds stipitate, dichoto- 
mous, each pinnule 2-4 divided to near the base, segments linear from a few inches to above a foot long, ^ to 1 inch broad when barren — 
narrower when fertile. Sori projecting from the margin — Ugena dichotoma, Cav. 
PLATE No. LXII. 
3. Lygodium fie.vuosum (Sw.) Stems climbing, fronds glabrous, or slightly hairy, pair of fronds stipitate-pinnate with the pin- 
nules again pinnate or variously lobed or sub-palmate, terminal segment linear lanceolate, all semilate, sori protruding from the margin. 
Common in most sub-alpine jungles on the western side of our Presidency — Malabar plains— Cuddap.ah and North Arcot 
hills— Nullay Mallays. 
PLATE No. LXIII. 
4. Lygodium Japonicum (Sw.) Stems climbing slender, glabrous or pubescent, fronds pinnate with the pinnaa again pinnate 
pinnules variously lobed, segments short, serrulate, the fertile ones much contracted, sori occupying the whole of the under surface or 
protruding from the mdLigin— Presl. ; Tent. Pterid. Suppl. 109.

(§ 2.) SCHIZ^E^. 
(a) Fructifications 2^aniculate on special contracted pinna^form appendages, 
ScHiz^E^, Smith, Mem. Acad. Turin, v. 419. 
(Ripidium, Bernhcirdi.—lioyAnAmm, 7?iV7iari.— Actinostachys, TFa^/uV;.- Belvisic-e, Sp. J/iVie/.— Acrostichi, Sp. Auctorum.— 
Osmundte, Sp. Auct. — ) 
Fructifications paniculate ; the spore-cases borne on the inner face of contracted fertile crests or appendages, which are digitato- 
pinnate or pectinato-pinnate, erect, incurved, and more or less connivent. — Spore-cctses bluntly ovate, having a many-rayed apical ring ; 
sessile arranged in one or two series on each side the costa of the linear segments, or pinnae of the appendages. Veins reduced to a 
costa or flabellato-dichotonious ; the venules excurreut in the apical teeth.
