3. A. hispidulum, Swartz, Syn. Fil. 124, 321.—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 $—#in. broad, colour olive- 
green, often red or reddish-brown when young, rhachises densely 
hispid-pubescent. Pinnules numerous, closely placed, petiolate, 
4-2 in. long, about +in. deep, dimidiate, rhomboidal, rigid, promin- 
eutly 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.—A. Rich, Fl. Nouv. Zel. 88; A. Cunn.

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, &. Br. Prodr. 155.—Rhizome long, stout,

black, shining, sometimes hairy towards the base, scabrous 
throughout. Fronds 14-3ft. long, 12-20in. broad, broadly 
deltoid, dark-green, copiously 3-4-pinnate; main rhachis flex- 
uous, black, glossy, glabrous or pubescent; secondary rhachises 
usually pubescent. Lower pinne large and broad, often 
12-15in. long, ascending, very compound; secondary pinne 
usually again divided. Pinnules very numerous; fertile small, 
i1lin. long, }-4in. deep, petiolate, dimidiate, broadly obliquely- 
oblong or rhomboid; lower margin straight or slightly hollowed, 
entire, upper and the rounded outer margin deeply toothed or
