1. Davallia tenuifolia, (Sw. Syn. Fil., p. 133) — Caudex creeping, woolly with subulate ferruginous scales, stipes long, frond erect 
ovato-lanceolate generally elongate, glabrous subcoriaceous brown, when dry, bi-tri-pinnate with the rachis compressed and winged (in other 
words bi-tri-pinnatifid) the segments or ultimate divisions approximate forked linear-cuneate truncate, the apex slightly erose, involucres 
terminal and solitary or in pairs short (transversely)-oblong slightly erose. {Hook. Sp. Fil. i, 186) ; (Davallia remota, Kaulf.) 
Coonoor, very common — Coimhatore kills, at an elevation of 5,000 feet only — Ananmllays—Coorg, dr. 
PLATE No. XVI. 
2. Davallia hullata, (Wallich Cat. n. 258)— Caudex creeping, clothed with copious subsquarrose ferruginous subulate crinite scales, 
frond deltoideo-ovate, submembranaceous tripinnate, fertile specimens copiously bullate on the upper surface, lower primary pinnae 
subopposite ovate acuminate, pinnules lanceolate deeply pinnatifid, segments entire or again inciso-pinnatihd, segments falcato-in curved 
linear acute, involucres oblong cup-shaped, truncate from the inside of the falcate segment arising from the sinus of a small inner tooth. 
{Hook. Sp. Fil. i, 169.) 
Anamallays, on rocks and trees 3,000 to 4,000 feet elevation— Wynaad — a rare fern. 
PLATE No. XVIL 
3. Davallia elegans, (Sw. Syn. Fil., p. 132.)— Caudex stout creeping, scaly and woolly, fronds tall subcoriaceous, ovato-acumi- 
nate, tri-quadri-pinnate, pinnules lanceolate, pinnatifid acuminate striated with pseudo-veins between the true veins, ultimate pinnules 
lobato-crenate, lobules entire or more usually one or two toothed, involucres half-cup-shaped, a little elongated sunk inserted upon the lobe, 
compressed tnincate at the mouth. {Hook. Bp. Fil. i, 164.)

PLATE No. XVIII. 
Prosaptia, Presl. Tent. Pt., 165. 
(Davallia, Auctorum; Humatse sp., Desvaux.) 
Sori indusiate oblongo-rotundate, immersed in a short marginal cyst open externally ; the receptacles terminal at the apex of 
the costa. Indusium sub-coriaceous, continuous with and scarcely differing from the under surface of the frond, forming an extrorse cavity 
in, as it were the substance of the frond itself. Veins simple from a central costa or costaeform vein ; the latter usually, and one or two 
of the upper veins (branches) sometimes soriferous. 
Fronds pinnatifid, rigid, subcoriaceous. Rhizome tufted decurrent. This genus differs from Davallia in the texture of the 
indusium, being homogeneous with that of the frond. {Moore.) 
1. Prosaptia contigua, (Presl.) — Tufted or with a very short somewhat creeping caudex, fronds aggregate, lanceolate attenuate 
at both extremities on a short stipes pinnatifid throughout from the margin almost to the costa glabrous, segments linear entire or sub- 
pinnatifid with one or more lobules towards the extremity, sori solitary terminal upon a segment or lobule. {Hook. Sp. Fil. i, 161) ; 
(Davallia contigua, Siu. Syn. Fil., p. 130) ; (Polypodium, J. Sm.) ; (Trichomanes contiguum, Forst. Prodr. n. 463.) 
Anamallay Hills, on trees and rocks, banks of the Toracadoo river, at an elevation of 4,500 fiitt — a rare fern. 
PLATE No. XIX. 
2. Prosaptia Emfrsonii, (Presl.) — Tufted, fronds aggregate, sessile lanceolate, pinnatifid from the margin half way down to the 
costa, attenuated and entire at the apex, the lobes oblong, obtuse entire, bearing 1 — 6 sori at the apices. {Hook. Sp. Fil. i, 161); 
(Davallia Emersonii, Hook. et. Grew, Ic. Fil., t. 105.) 
Anamallays, viith tJm preceding. Palghat Hills— a rare fern.

TRIBE I. (§ 5) VITTARIE.^. 
ViTTAEiA, Smith Mem. Acad. Turin, V, 413. 
(Runcinaria, Midler; Aristaria, Miiller Parenchymaria, Milller.) 
Son non-induciate, linear, continuous ; the receptacles lying in an extrorse marginal furrow, t. e., a groove open exteriorly in the 
extreme margin of the frond. Veins obscure, simple, combined at their apices by the receptacle.
