feet. Boutan, Griffith. Ceylon, Gardner, n. 1 2 2 6 , alt. 2 3 0 0 feet.—Like not a
few others o f the Niphobolus group, this is a species, and I believe a very distinct
one, more easily recognized by the eye than defined b y words. It is remarkable
for the bright, deep, ferruginous colour o f the w h o l e tomentum, and for the
fronds not unfrequently having angles and even long-acuminated lobes at the
margin, while the base tapers down so gradually as to form a wing to the short
stipes. N. sticticus of Kze. in Hohenacker, is identical with this ; and, possibly,
Niphob. fissus o f Blume is not really different.
308. P. (Niphobolus) Lingua, Sw.; caudex very long
creeping rather slender flexuose paleaceous with ferruginous
subulate scales, stipites 3-6 inches and more long remote
always ai'ising from a short very paleacous branch of the
caudex, upper scales longest and spreading, fronds 4-8
inches long lanceolate or ovate or oblong obtuse or acumi­
nated densely and very compactly stellato- and sometimes
subsquamuloso-tomentose at length glabrous above, sori
subelevated copious in 4-6 close series between the primary
or costular veins and from 9-20 between the secondary
veins.—Sw. Syn. Fil.p.29.

but an easily-recognized species.
309. P. (Niphobolus) detergibile, J . Sm. ? vix Don ?; cau­
dex rather stout densely fibroso-radicant paleaceous especially
about the base of the stipites with finely subulate ferruginous
scales, stipites 4-6-8 inches long aggregated clothed as is
the whole plant with a dense compact mass of whitish or
ferruginous stellated tomentum which not unfrequently peels
off in dense cottony masses from the upper side of the frond
leaving that part quite naked and glabrous, fronds from 4-16
inches long | - 1 | inch broad carnoso-coriaceous younger
ones often ovato-acuminate mature ones lanceolate finely
