1 7. elongatum 4. Cunn. Precir. (1836) n. 231.—Rhizome short, stout, 
erect or inclined, clothed with the bases of the old stipites; rootlets many, 
rigid and wiry. Fronds 4-8 at the top of the rhizome. Stipes 3-9 in. long, 
stout, mgid, terete, rough below and furnished at the very base with a 
tuft of linear bristles, not winged above. Fronds 3-8in. long, 14-3 in. 
broad, ovate-deltoid, acuminate, rigid, dark olive-green, often coated on the 
upper surface with mosses and hepaticae, 2-3-pinnatifid; main rhachis 
scarcely winged except at the very top. Primary pinnae close, rhomboidal- 
lanceolate, pinnate at the base, pinnatifid above; secondary imbricating, 
oblong-cuneate, deeply incised or pinnatifid. Ultimate segments or lobes 
rather broad, usually incised at the tips, the teeth acute; veins stout, 
_ branching, one to each tooth. Sori numerous, in the axils i the lobes of 
the secondary pinnae. IJndusium narrow funnel-shaped, quite free; mouth 
scarcely dilated, entire or very slightly 2-lpped. Receptacle stout, rigid, 
exserted.—Raoul Chorx (1846) 48; Hook. Ic. Plant. viii (1854) t. 701; Sp.

Closely allied to the widely distributed 7’. rigidum Swartz, and considered to be 
a variety of it by Mr. Baker and other pteridologists. But the frond is broader and 
more deltoid, the rhizome is not creeping, and the stipes and rhachis quite wingless ; 
the pinnae are more imbricate and less divided, and the segments are broader and 
shorter. It is also found in the New Hebrides and New Caledonia. 
3. LOXSOMA R. Br. 
Rhizome stout, woody, creeping, paleaceous. Fronds erect, coriaceous, 
opaque, quite glabrous, 3-4-pinnate ; stipes long. Veins free, not anasto- 
mosing. Sori marginal, in a sinus of the teeth or lobes of the frond, termi- 
nating a vein. Indusium cup-shaped or almost urceolate, coriaceous ; 
mouth truncate, entire. Receptacle long, columnar, exserted. Sporangia 
numerous, mixed with jointed hairs, obovoid or pyriform, girt by a com- 
plete oblique ring, bursting vertically. 
A genus of a single species, endemic in the northern portion of the Dominion.

—Rhizome long, stout, tortuous, densely clothed with linear red-brown 
hairs. Stipes 1-2 ft. high, erect, pale- -brown, glabrous, smooth and polished. 
Fronds 9-24 in. long, 6-12 1n. broad, broadly triangular, coriaceous, dark- 
green above, glaucous-white or pale-green beneath ; “rhachis polished, chan- 
nelled. Primary pinnae rather distant, ascending, the upper alternate, tlie
