Trichomanes. | FILICES. 943, 
1. T. reniforme, Forst. Prodr. n. 462.—Creeping over the ground 
in moist forests, or clothing the trunks of trees and rotten logs. 
Rhizome stout, hard, rigid, wide-creeping; rootlets woolly. Stipes 
2-8in. long, erect, wiry, glabrous. Fronds 2-4in. broad, quite 
entire, broadly reniform with a deep sinus, dark-green and trans- 
lucent when fresh, brown and almost horny when dry, flat or 
undulate, glossy, quite glabrous; veins radiating from the base, 
numerous, close, prominent, repeatedly dichotomous, spurious 
venules wanting. Sori very numerous, crowded, often encircling 
the whole of the margin of the frond. Indusium narrow cup- 
shaped or almost bell-shaped. Receptacle far-exserted, stout, 
columnar, covered with sporangia.—A. Rich. Fl. Nouv. Zel. 95;

NortuH anp SoutH Isnanps, STEWART IsLAND, CHATHAM IsLANDS: From 
the North Cape southwards, abundant in damp woods, except on the eastern 
side of Canterbury and Otago, where it is rare and local. Sea-level to 3000 ft. 
Kidney-fern ; Raurenga. 
A very distinct and beautiful species, quite unlike any other. The frond 
differs from that of all the other species in having from 4 to 6 layers of cellules. 
It is confined to New Zealand, its reported occurrence in Australia (Handb. 
N.Z. Fl. 747) not having been confirmed. 
2. T. Lyallii, Hook. and Bak. Syn. Fil. 77.—-Small, pendulous, 
very delicate, clothing the trunks of trees in damp forests. 
Rhizome branched, creeping, capillary, sparingly clothed with 
simple or stellate red-brown hairs. Stipes 1-2in. long, very 
slender, filiform. Fronds 3-ldin. long and broad, deltoid or sub- 
orbicular in outline, delicately membranous and diaphanous, digi- 
tately or flabellately divided almost to the base. Segments simple or 
dichotomously branched, linear, obtuse, flat, minutely denticulate ; 
margins ciliated with branched rufous hairs. Sori few or many to a 
frond, deeply sunk in the tips of the segments. Indusium obconical, 
the width of the mouth about equalling the depth of the tube; 
margins ciliated, not dilated nor bordered. Receptacle included.— 
Thoms. N.Z. Ferns, 45; Field, N.Z. Ferns, 70, t. 5, f. 4. Hymeno- 
phyllum Lyallii, Hook. f. Fl. Nov. Zel. ii. 16; Handb. N.Z. Fl. 355. 
NortH anpD SoutH Istanps.-— From the Great Barrier Island and Cape 
Colville southwards, not uncommon in dense moist forests, but rare or absent 
on the east coast of the South Island, plentiful in Westland and the south-west 
of Otago. Stewart Istanp: Mount Anglem, Kirk. Sea-level to 3000 ft. 
Exactly intermediate between J’richomanes and Hymenophyllum, so far as 
the structure of the indusium is concerned. It is purely a matter of taste as to 
which genus it should be referred to.
