Hab. S. Brazil, Gardner, 128 ; Venezuela, Fendler, 216.—Most like P. suspensum in
cutting, but suberect, and the texture so rigid that the frond will scarcely adhere to
paper.
^ 176. P . pulchrum, M. & G. ; rhizome stout, shortly scaly ; st. suhtufted 3-4
in. 1., rigid, erect, blackish, glossy ; f r . 12-18 in. 1.,‘ 2-3 in. hr., cut down’ into

Hab. Mexico and West Indies to Peru and South Brazil.—Well distinguished by its
nnely-cut pectinate habit and simple oblique usually distinctly-marked veinlets with the
son tCTminal upon them. P. ferrugineum (M. & G.), Hk, Sp. 4. p. 182. and P. apicula-
turn (Kze.), Hk. I. c. p. 185. both seem small forms of this, rather thicker in texture than
usual. P. L Herminieri, Fée, Fil. Ant. t. 12. belongs here.

bright-ferrugmous ; st. 3-6 in. 1., firm, erect ; f r . 1-3 ft. 1., 4-6 in. hr., cut down

pubescent ; vems obscure, forked ; sori in a single medial im e .—Mett. Polyp,

but the scales are different, and the lower pinnæ not reduced.
179. P . pectinatum, L. ; rhizome stout, fibrillose ; st. rigid, erect, 2-6 in. 1.,
naked or finely villose ; f r . 1-2 ft. 1., 2-6 in. br., cut down to the rachis into

Ilk . Sp. 4. p . 204.
Hab. Mexico and W. Indies to Peru and Brazil ; common.—Similar in habit to the two
last, but larger, with the veinlets pellucid in the living, and consequently inconspicuous in
the dried plant, usually twice forked, and producing the sorus from the tip of the lowest
branch.
180. P . meridense, Klotzsch ; rhizome creeping, the scales fibrillose, dark-
brown ; St. 3-6 in. ]., wiry, black, scarcely at all villose ; f r . 6-9 in. 1., 3 in. br.,

scales ; st. 6-9 in. 1., firm, erect, ebeneous, finely villose ; f r . 1 ft. or more 1.,
3-4 in. hr., cut down to the rachis into oiisourely undulated suhacute horizontal
pinnæ j in. hr., dilated a t the base, the lowest not reduced ; texture coriaceous ;
rachis and both sides finely villose ; veins immersed, once forked ; sori in tivo
rows midway between the edge and inidrib.—B k . Sp. 4. p . 206.
Hab. Andes of Ecuador, Spruce, 5281.—Very near tbe last, from which it differs by its
finely-villose stem and surface and medial sori. The two are much more coriaceous than
pectinatum, with the veins hidden, and lower pinnæ not reduced.
182. P . Moritzianum, Link ; rhizome stout, creeping ; scales lanceolate-subulate,
ferruginous ; st. 4-6 in. 1., naked, glossy, erect ; f r . erect, 12-18 in. 1., 3-4

lin. hr., which are slightly dilated a t the base and then narrowed gradually to
an acute point ; texture th in ; rachis and hoth sides finely villose ; veinlas
