This was placed with H. sanguinolentum by Hooker, and is doubtless closely allied 
to it. But it 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/Walld. Sp. Plant. v (1810) 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 membranous, 3-9 in. long, 13-4 in. 
broad, triangular with usually a broad base, acuminate, quite glabrous, 
2-3-pinnatifid. Rhachis with a broad much-crisped wing which extends 
a most to the base of the stipes. Primary pinnae ?—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. in Annals Bot. v (1890-91)

NortH AND SoutH ISLANDS, Stewart IstanpD: Not uncommon in damp woods. 
Sea-level to 2000 ft. 
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.

5. H. atrovirens Col. in Tasm. Journ. Nat. Sci. u (1846) 186.—Usually 
terrestrial. Rhizome slender, wiry, creeping. Fronds few, somewhat 
rigidly erect, membranous, dull dark-green, 2-6im. high, $—-1 in. broad, 
linear-oblong or lanceolate, quite glabrous, 2-pinnatifid. Stipes about half 
the length of the frond, winged almost to the base; rhachis flexuose, 
winged throughout, wings flat, not crisped. Pinnae 5-10 on each side, 
alternate, the lowest usually the largest, }-2 in. long, erecto-patent, irregu- 
larly pinnatifid. Segments simple or forked, linear, obtuse, flat, quite entire. 
Sori few, terminating the segments, quite free. Indusium small, ovate, 
2-valved almost to the base, slightly broader than the segments; valves 
obtuse or subacute, entire or jagged.—Cheesem. Ill. N.Z. Fl. 11 (1914) t. 235.
