STEWART ISLAND: Ulva, rare, Kirk. Sea-level to 3000 ft. 
Confined to New Zealand, but very closely allied to the widely spread 
T. rigidum, Swartz. 
7. T. elongatum, A. Cunn. Precur. n. 231.—Rhizome short, 
stout, erect or inclined, clothed with the bases of the old stipites; root- 
lets many, rigid and wiry. Fronds 4-8 at the top of the rhizome. 
Stipes 3-9 in. long, stout, rigid, terete, rough below and furnished 
at the very base with a tuft of linear bristles, not winged above. 
Fronds 3-8 in. long, 14-3 in. broad, ovate-deltoid, acuminate, rigid, 
dark olive-green, often coated on the upper surface with mosses and 
hepaticee, 2-3-pinnatifid ; main rhachis scarcely winged except at 
the very top. Primary pinne close, rhomboidal-lanceolate, pin- 
nate 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 of 
the lobes of the secondary pinne. Indusium narrow funnel-shaped, 
quite free ; mouth scarcely dilated, entire or very slightly 2-lipped. 
Receptacle stout, rigid, exserted.— Raoul, Choixz, 38; Hook. Ic.

Closely allied to the widely distributed 7. rigidwm, 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 pinne are more imbricate and less divided, and the 
segments are broader and shorter. It is also found in the New Hebrides. 
3. LOXSOMA, R. Br. 
Rhizome stout, woody, creeping, paleaceous. Fronds erect, 
coriaceous, opaque, quite glabrous, 3-4-pinnate ; stipes long. Veins 
free, not anastomosing. Sori marginal, in a sinus of the teeth or 
lobes of the frond, terminating 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 complete oblique ring, burst- 
ing vertically. 
A genus of a single species, endemic in the northern portion of the colony.
