O b s . Amoiigst Gunn’s specimens of this plant and Hypolepk tenuifolia, I find specimens of S y p . tmmfoha.
Hook, (a New Zeaiaud species), whicli I regi-et haring overlooked previously. It may be known by its small size
and simply bipinnate fronds, and is perhaps ouly a small state of U. tenuifolia. Mr. Gunn’s specimens are from
the cataracts of the South Esk Eiver and Wcsteru Mountams, elev. 2000 feet (ii. 1544 and 1544 ?).

D is t r ib . New Zealand, Java.
Roots fibrous. Fronds an inch to a span long, tufted, linear-oblong, ovate or lauceolate, coriaceous, opaque,
scaly at the very base of the stipes, perfectly glabrous elsewhere, deeply pinnatifid. Pinnules somewhat distant,
linear, blunt, dccurrent, quite entire, or lobed, or subpimiatifid. often irregularly, with one or two lobes lengthened
or running out into a tail. Son round or oblong. Rachis aud short stipes winged nearly to the base.—Dwarf
states have small, linear, lobed fronds.

A very abundant tropical genus of Ferns, generally growing on trunks of trees, distinguished by the naked

pinnatifid, perfectly glabrous, rising from a stout, creeping rhizome. (Name from 4>vpa, a swelling; in allusion to
the thickened base of the articulated frond.)

A very common and variable -piant.—Rhizome stont, creeping, generally quite glaucous, partially scaly, sometimes
thickly covered with membranous paleæ. Fronds numerous, 3 inches to 14 foot long, coriaceous, perfectly
smooth, shining, with a thickened mai'gin ; some entire, lanceolate, acute, others broader and pinnatifid ; pinnules
close or distant, nan-ow-linear or broadly oblong ; margins thickened, blunt or acute. Sori numerous, large, globose
or oblong, partially sunk in the frond. Costa very stout aud prominent. Stipes stout, scarcely winged above,
obscurely jointed on to the rhizome.

Rhizome creeping, often short, scaly. Fronds densely crowded, 4 inch to a foot long, quite glabrous, rarely
pubescent, sometimes pilose or ciliated, erect, very coriaceous, linear-lanceolate or obovate-laiiccolate, blunt, or narrowed
at the point, (piite entire, narrowed into a sliort winged or margined stipes. Sori oblong or linear, oblique,
iu one series on each side the obscure costa, in small varieties becoming couflueiit into a mass. VHns wholly immersed,
forked, free. (Name from ypapp-q, a line; in alliision to the linear sorus.)

D is t r ib . South-eastern Australia and New Zealand, Fuegia, and the Falkland Islands.
This is an extremely variable Fern, often cUiated with caducous hairs, especially on the stipes. Mpine specimens
form deuse Moss-like patches of small, obovate, coriaceous, blunt fronds, 4 inch high, with confluent son
towards the apex. In dry rocky places, again, it assumes the form of a very narrow, rigid, why frond. The scales
on the rhizome also vary extremely iu length and colour.

Principally tropical Ferns, with (rarely simple) pinnate, bi-tripinnate, tufted fronds, having no rhizome or a
veiy short one.— Sori naked, linear, occupying the veins and venules, hence often running in lines and forking ; also
covering the spaces between the veins, and then becoming confluent. (Name from yvpvo% naked, and ypapp-q, a
line; in allusion to the liuear sorus, which has uo indusium.)

D is t r ib . Australia, New Zealand, Pyrenees of Northern Spain.
This little plant is abundant in extratropical Australia and Tasmania, and has also been gathered iu the
Pyrenees, but I know of no other countries which it inhabits.—Fronifs densely tufted, 3-5 inches long, villous,
often glandular, pinnate ; roots of numerous tufted fibres. Pinna 2-5 liues long, alternate, distant, shortly stipitate,
cuncatc or flabellate, more or less incised or lobed, rarely quite entire. Sori linear, scattered, often confluent.
