Var. polymorphum Cheesem.-—Fronds smaller, pale-greem, usually simply pinnate, 
rarely branched at the base. Surfaces of the pinnae and indusia quite glabrous.—

Kermapurc Istanps, Norra Isnanp: Not uncommon in woods at low elevations, 
usually in rich alluvial soils. Souru ISLAND : Apparently rare and local. Nelson—

Sea-level to 1000 ft. , 
Also in Norfolk Island, east Australia, Fiii, New Caledonia, New Hebrides, Java, 
and southern China. 
3. A. hispidulum Swartz Syn. Fil. (1806) 124.—Rhizome short, stout, 
creeping. Stipes 6-15in. long, stout, erect, scabrous, dark-brown or 
almost black, more or less clothed with short greyish-white pubescence 
when young, becoming almost glabrous when old. Fronds broad, 6-12 in. 
or more across, dichotomously forked at the base, both forks irregularly 
flabellately divided into 3-7 linear secondary divisions 3-8 in. long by 
18 in. broad, colour olive-green, often red or reddish-brown when young, 
rhachises densely hispid-pubescent. Pinnules numerous, closely placed, 
‘petiolate, 4-$ in. long, about jin. deep, dimidiate, rhomboidal, rigid, pro- 
minently nerved, more or less hispid, especially on the under-surface, upper 
margin and the obtuse tip finely toothed, lower margin entire. Sori 
numerous on each pinnule, contiguous, placed in the notches of the upper 
and outer margins. Indusium orbicular-reniform, minutely hispid. —

Krrmapre Isuanps, Norra Istanp: Abundant as far south as the Hast Cape 
and Raglan, from thence somewhat rare and local to Cook Strait. SourH [SLAND:

The rather harsh hispid-pubescent fronds distinguish this from all the other New 
Zealand species. Outside New Zealand, it extends through the Pacific islands and 
Australia to tropical Asia and Africa. 
4. A. formosum R. By. Prod. (1810) 155.—Rhizome long, stout, creep- 
ing, scaly. Stipes 1-3 ft. high, dark purplish-black or quite black, shining, 
sometimes hairy towards the base, scabrous throughout. Fronds 1}-3 ft. 
long, 12-20in. broad, broadly deltoid, dark-green, copiously 3—4-pinnate ; 
main rhachis flexuous, black, glossy, glabrous or pubescent; secondary 
rhachises usually pubescent. Lower pinnae large and broad, often 12-15 in. 
long, ascending, very compound ; secondary pinnae usually again divided. 
Pinnules very numerous; fertile small, 44 in. long, ++in. deep, petiolate, 
dimidiate, broadly obliquely-oblong or rhomboid; lower margin straight _ 
or slightly hollowed, entire, upper and the rounded outer margin deeply 
toothed or incised; texture firm; under-surface glabrous or pubescent with
