TRICHOMANES. 
TRICHOMANES FILICULA. (Bory.) The fern here figured is the true Pelicula of Bory,— Plate No. VII of the Ferns 
of Southern India is the Schmidtianum of Van den Bosch and is included by Sir W. Hooker under the 7. pyxideferum L. and the name 
_on the plate should be altered from Filicula to pyxidiferum L. The true Filicula is distinguished by having a distinctly two-lipped invo- 
lucre and belongs to the section or subgenus Didymoglossum, but is not otherwise distinguishable from pyxidiferum, and I have always 
looked upon them as the same species, they are both common on the Nilgiris and throughout India, 1 annex Sir W. Hooker's descrip- 
tions of both species with localities, 
T. FILICULA. (Bory.) ; rhizome wide-creeping, tomentose, rather slender, stipes 1-2 inch long, naked, slightly winged

boidal, pinnatifid down to a narrowly-winged rachis ; the lower pinnule again deeply pinnatifid ; ultimate segment linear ; texture firm, 
membranaceous ; a central costa in each segment, spurious venules none or indistinct, sori 1 to 4 to a pinna, axillary or terminal on the 
segments ; tube sunk or somewhat exserted, the mouth very distinctly two-lipped, the lips subtriangular with a rounded apex, —Hk. Sp.
