decurved, opaque, dull brownish-green, 2-6 in. long, 1-24 in. broad, 
broadly ovate to ovate - lanceolate, acuminate, 3—4-pinnatifid. 
Stipes 1-3 in. long, usually narrowly winged above, villous with 
scattered spreading hairs; rhachis narrowly winged throughout, 
rather slender, flexuous, more or less villous, as are the partial 
rhachides and coste. Primary pinne closely placed, often over- 
lapping, lanceolate-deltoid ; secondary rhombic-ovate, again once or 
twice pinnatifid. Ultimate segments crowded, very narrow, linear, 
obtuse, flat. Sori numerous, terminating the segments, free. In- 
dusium broadly ovate, obtuse or subacute, broader than the 
segments, 2-valved to the base; valves smooth, entire.—Kirk in

This was placed with H. polyanthos by Hooker, and is doubtless closely 
allied to it. Butit differs markedly in the much more finely cut 4-pinnatifid 
fronds, in the villous stipes, rhachis, &c., in the much narrower segments, and 
in the smaller sori. 
4. H. australe, Wild. Sp. Plant. v. 527.—Forming matted 
patches on rocks or among moss, more rarely on the trunks of trees, 
pale-green when young, becoming lurid-green in age. Rhizome 
creeping, branched, wiry. Fronds erect or decurved, very mem- 
branous, 3-9in. long, 14-4in. broad, triangular with usually a 
broad base, acuminate, quite glabrous, 2-3-pinnatifid. Rhachis 
with a broad much-ecrisped wing which extends almost to the base 
of the stipes. Primary pinne #~2 in. long, rhomboidal-lanceolate, 
spreading, often decurved at the tips, deeply pinnatifid ; secondary 
again pinnatifid or irregularly forked. Ultimate segments narrow- 
linear, obtuse, quite entire, more or less crisped, rarely flat. Sori 
usually numerous, terminal on the segments, free. Indusium 
orbicular or broadly ovate, usually broader than the segments, 
2-valved to the base; valves broad, rounded, entire or slightly 
erose.—Bak, Annals Bot. v. (1890-91) 193. H. javanicum, Spreng.

A common plant in Tasmania, and from thence extending northwards to 
Malaya, India, and Ceylon. It is easily distinguished from the other New 
Zealand species by the broad conspicuously crisped wing of the rhachis and 
stipes.
