Kermaprec Isntanps, NortH anp SoutH Isnanps, CHATHAM ISLANDs, 
‘SrEwart IstAND, AUCKLAND IsnANpDS: Abundant in woods throughout. Sea- 
level to 3000 ft. 
Also found in Polynesia, Java, and the Philippine Islands. The veinlets 
often fork towards the tips of the segments, and in profusely fruited specimens 
there is usually a sorus at the tip of each veinlet. When the fork of the veinlet 
is very close to the tip of the segment the two sori are often included in a single 
indusium, the valves of which, however, are more or less cleft at the apex. All 
gradations can be traced between two indusia placed side by side, and a single 
indusium containing 2 receptacles. Mr. Colenso’s H. megalocarpwm and H. 
polychilum, named specimens of which appear to me to be identical, are founded 
mainly on this peculiarity, and show no other differences. His H. erecto-alatwm 
was separated on account of the broader crisped wing of the rhachis, but the type 
specimens prove this character to be a very obscure and uncertain one. 
9. H. scabrum, A. Rich. Fl. Nowv. Zel. 90, t. 14, £. 1.— 
Usually clothing the trunks of trees, rarely terrestrial. Rhizome 
long, creeping, wiry, more or less bristly with reddish-brown scales. 
Fronds very variable in size, usually from 6in. to 20 in. long, but 
luxuriant specimens sometimes attain 30in., 2-5 in. broad, ovate- 
deltoid or ovate-lanceolate or linear-oblong, acuminate, mem- 
branous, dark olive-green or olive-brown, erect or pendulous, 
3-4-pinnatifid. Stipes 2-6in. long, not winged, more or less 
densely clothed (as are the primary and secondary rhachides and 
cost) with reddish-brown jointed hairs; rhachis winged above, 
wingless below. Primary pinne 1-3in. long, close or rather dis- 
tant, spreading or erecto-patent, rhomboidal-lanceolate or -oblong, 
acuminate; secondary deeply pinnatifid or 2-pinnatifid. Ultimate 
segments linear, obtuse, flat, quite entire. Sori numerous, terminal 
on the lateral segments on koth sides of the pinna. Indusium 
rather small, orbicular or ovate-orbicular, 2-valved to the base ; 
valves usually toothed.—A. Cunn. Precur. n. 235; Raoul, Choix, 39 ;

NortH and SoutH Isnanps, CuHatHam Isnanps: Moist forests from 
Hokianga southwards, not uncommon. Sea-level to 3000 ft. 
A distinct and beautiful species, easily recognised by the reddish hairs on 
the stipes, rhachis, and coste, and by the dark colour of the frond. It 1s 
confined to New Zealand. 
10. H. flabellatum, Lad. Pl. Nov. Holl. ii. 101, t. 250.—Densely 
matted, usually clothing the trunks of trees. Rhizomes long, wiry, 
creeping, often much branched and interlaced, more or less clothed 
with yellow-brown woolly hairs. Fronds very variable in size and 
shape, usually 3-9in. long, but sometimes reduced to less than 
lin., at other times attaining a length of 12in., the smaller speci- 
mens generally ovate and erect, the longer ovate-lanceolate to 
lanceolate or linear-oblong and pendulous, pale shining-green or
