southward to Peru.—Resembling 11. sericeum in habit, but much thinner m texture, and
the rachis winged.
46. H. senceitm, Sw. ; si. 2-4 in. 1., wiry, naked ; f r . pendent, 6-24 in. L, 2-3
in. hr., elongato-ohlong, obtuse or acuminate, simply pinnatifid ; raclas densely
clothed with close tomentum, free throughout ; pinnce 1-2 m. 1., very luiineroiis,
opposite, rhoiiihoidal-lanceolate, with a cuneate base and niuoli-acummated ape.x,
sometimes only iust.crenated, sometimes pinnatifid more th a n halfway down to
the rachis, the'substance almost coriaceous and soft, with a dense coating ot
tomentum : veins prominent, forked with nearly parallel branches, and often
famished with curious niembranaoeous wings or lainellæ ; son very numerous
to a pinna, small, termina l on the apex of the pinnæ and lÿ e r a l segments ;
rounded, shaggy, with strong reddish-brown hairs.—f t* , bp. L .p . 92.
Hab. Tropical America, from Cuba, Jamaica, and Mexico s o u t h w a r d to Peru and
Brazil.—A curious species, quite peculiar in habit and texture, which Van den BoscU
divides into eight ; viz. sericeum, eriophm-wn, Cúbense, Sturm, plumosum, Kaulf., Karstem-
anum, speciosum, asterothrix, Kunze, and tomentosum, Kunze.

down ; valves denticulate a t the apex, and shaggy like the frond.—Trichomanes
Malingii, H k . Gard. Ferns, t. 64.
Hab New Zealand.—The connection of this curious novelty is certainly with H. sen-
ceum, from which it differs principally in the total absence of a connecting membrane
between the veins of the pinnæ, which, in one form of the South American plant, is par-
tially deficient.
48. H. lineare, Swartz ; st. about 1 in. 1., slender, villose ; f r . flaccid, pendulous,
3-8 in. L, 1-2 in. br., linear, elongated, fully pinnate ; rachis slender, wavy,
yillose, free throughout ; pinnoe spreading, ovato-jliomhoidal, deeply cut into
simple or forked linear lobes, the surface and margin densely hairy ; sori 2 to 6,
termina l on the lateral segments ; invol. about as broad as tlie segments ; vMves
rounded, strongly ciliated.—I I. elegans, Spr. B k . Sp. 1. p . 91. H. trifiduni,

Hab Tropical America, from Jamaica and Mexico southward to Brazil and Peru,
asoendin» on the Andes of Ecuador to 12,000 ft., and occurring also in the Mauritius
from which we have just received specimens from Dr. Meller.—This species is very ñaccid
in habit, and the long narrow fronds form densely interlaced masses on rocks and trees.
Van den Bosch gives the three plants already named as distinct, and his procerum, inclio-
phyllum, Gngeri, and Moritzianum are also included here.

6-18 in. 1., 2-6 in. hr., linear-ohlong and pinnate, or broadly oblong and
bipinnate ; racMs wavy, villose, free throughout ; lower pinnæ m the bipinnate
form often with several pairs of pinnules ; p in n l. 1-3 in. 1., deeply pinnatihd
principally on the upper side ; ult. segm. 1-2 lin. 1., 1 lin. hr., tlie surface and
margin denselv hairy ; sori 6 to 12, terminal on the lateral segments ; mvol, sunk

01, in part.
Hab. Andes of Ecuador and Columbia, ascending to 13,000 ft.—Closely allied to
II. lineare in its manner of growth, but a much larger plant, with broader and shorter
segments. The original II. pulchellum appears to be a small state of sericeum. This and
the preceding are the only simply pinnate hairy species with divided pinnæ.
50. H. Catherines, Hk., MSS. ; st. 1-2 in. 1., erect, wiry, slightly ciliated ; f r .
2-3 in. 1., 1-1-J in. hr., oblong, fu lly bipinnate ; main rachis free throughout,
slightly ciliated ; lower pinnæ broadly liiomhoidal, cleft down to the racliis ; the
lower pinnl. several times forked, with very narrow linear ciliated about
2 iin. I. ; sori 6 or more to each pinna, terininal on the segments of the upper
pinnæ on both sides, considerably broader th an the segments, the cuneate base
sunk in the frond ; the ciliated valves divided about halfway down.
Hab St Catherine’s Peak, Jamaica, at an elevation of 6,000 ft., Wilson; Guadeloupe,
LTIerminier.—A small, neat, deeply-cut plant with inconspicuous hairs The Guadeloupe
plant was distributed by M. Fée as II. prolrusum. Hook., which belongs to the
glabrous section, and is a form of II. polycmthos.
51. IT. Pastoensis, Hk., MSS. ; st. 4-6 in. 1., stout, erect, densely villose ; f r .
6-12 in. 1., 4-6 in. br., ovate-acnminate, fully bipinnate ; rachis strong, erect,
denselv clothed with ferrugiiious hairs ; pinnæ ovate-lanceolate, recurved ; lower
pinnl. L in. or more 1., divided down nearly to_ the costa into very long narrow
linear segments, h a iry principally on the rachis and margin ; sort 12 to 20, te rminal
on and broader th an the segments ; invol. orbicular, free, deeply 2-valved ;
the valves only ciliated,
Hab. Volcano of Pasto, Andes of N. Ecuador, /ameso«.—This and the preceding (both
new species) are interesting, as showing a much more divided type of form in the trond
than was known previously in this section.

Hab Ee»arding these two as British plants alone, we should pronounce them readily
sepa^birby the characters given, which*are taken from our two indigenous p ants ; bu ,
lookin» abroad, wo find them connected by every intermediate stage of gradation.
