A. venulosum, Wall. A. obscurum, B l.
Hah. F . India, Philippines, Malayan Peninsula.—This differs from the three preceding
by the under side being nearly or quite naked, and in tlie position of the sori. A. callosum,
Blume, quite agrees with this, except that there is a large prickle-like gland at the base
of the pinnæ, and sometimes also of the veins.

oblong lobes ; t e x t u r e subcoriaceous ; both s u r f a e e s naked ; c o l o u r bright-green ;
v e i n s about 9 on each side, conspicuous above, witb a sorus on each midway to
the edge.—H k . Sp. 4. p. 71.
Hab. Fernando Po.—A large plant, most like N. truncatum in habit and texture, but
the rhizome creeping.
Kronds large, pinnate ; caudex erect or suherect. Sp. 177-196.
f Pinnm entire or slightly lohed, so that most ofthe veinlets unite. Sp, 177-184.
177. N. glandulosnm, J . Sm. ; st. tufted, 1 ft. or more 1., naked or slightly
villose ; / r . 1 foot or more L, 4-6 in. hr., with 8 1 2 spreading pinnm on each

margin entiie or slightly lohed, the base abruptly truncate and sometimes
auricled; texture papyraceo-herbaceous; rachis and under surface naked or
slightly villose, sometimes g la n d u la r; fertile pinnm contracted, the main veins
