1. Alsophila lateh'osa (Wall.) Stipes and main racMs muricated with short elevated points, fronds bi-pinnate. pinnaj lanceo- 
iate, pinnules narrow-lanceolate, acuminate, pinnatifid, almost to the rachis, segments narrow-oblong, acute falcate, sub-coriaceous, serrated, 
rachis and costa with small bullate scales, and one generally at the base of the sorus, veins all once forked, sori much elevated, cylindrical, 
copious, occupying nearly the whole segment — Hook. Sp. Fil. i, 37. Pohjpodium latehrosum. Wallich.

This is the common tree fern.

2. Alsophila crinita (Hooker.) Stipes and main flexuose rachis pale colored, rough witli minute points and muricated with 
very short blunt black spines, fronds bi-pinnate, coriaceous, rachis everywhere hairy above, beneath clothed as well as the costa with ciliated 
scales, some short and minute, the majority very long slender appressed resembling coarse shaggy hair, pinnules sessile, narrow-lanceolate 
gradually tapering into a very slender point deeply pinnatifid almost to the rachis, segments narrow, ovate, oblong, rather obtuse, falcate, the 
margin (when dry) strongly recurved, pale beneath where the costa and even the veins are often hairy, veins forked, sori occupying nearly 
the whole length and breadth of the segments, and in a measure covered by the crinite scales — Ilool-. Sp. Fil. 1. 54. 
Nilgiris — a ravine on the road from Ootacamund to the Davie Shola — Sisparah ghat, common — Higher ranges of the Anamallays.

3. Alsophila glabra (Hook.) unarmed, fronds bi-pinnate, pinnas ovato-lanceolate, nearly sessile acuminate, pinnatifid about one-third 
down to the rachis segments, ovate, slightly falcate, serrated, tufts of hairs in the axils of the pinna% rachis and costa more or less strigose 
and scaly, — sori situated on the middle of each veinlet, therefore in a double line on each segment — Hooker, Sp. Fil. 1, 51. Gymaosphsera
