scattered white hairs. Pinnules of the barren frond larger, often 3in. long 
or more, more membranous, upper and outer margins deeply lobulate, the 
lobules incised. Sori numerous, placed in shallow depressions at the top of 
the teeth or lobules, broader than long, transversely oblong or oblong- 
renitorm.—Hook. Sp. Fil. ii (1858) 51, t. 868; Hook. f. Fl. Nov. Zel: ii

o. A. affine Willd. Sp. Plant. v (1810) 448.—Rhizome long, creeping, Mob 22% 
stout, clothed with glossy dark chestnut-brown scales. Stipes 4-12 in. 
long or more, stout, erect, shining-black, rough and scaly at the very base, 
smooth and polished above. Fronds 6-15 in. long, 3-9 in. broad, ovate- 
deltoid in outline, bipinnate or tripimnate at the base, pale-green above, 
usually glaucous beneath, quite glabrous or the secondary rhachises pubescent 
above. Pinnae 2-3 pairs with a long terminal one sometimes 6-9 in. long, 
in large specimens the lowest pair again branched. Pinnules 4-1 in. long, 
4-2 in. deep, petiolate, dimidiate, broadly obliquely-oblong or rhomboidal ; 
lower margin straight, entire, base truncate ; upper margin and the obtusely 
rounded apex deeply crenate-toothed ; texture firm, subcoriaceous. Sori 
numerous, rather large, 6-14 to a pinnule, placed in small notches at the 
tips of the lobes of the upper and outer margins, not in the sinuses between 
the lobes. Indusium orbicular-cordate or reniform.—Hook. and Bak. Syn.

KERMADEC [sLANDS, NoRTH AND SoutH Isntanps, Stewart ISLAND, CHATHAM 
istanps: Abundant in lowland districts throughout. 
Also in Australia, according to Bentham (FI. Austral. vii (1878) 724). Very variable 
in size, the amount of hranching of the frond, and in the size and shape of the pinnules. 
When growing on exposed rock-faces it is often dwarfed to an inch or two. Most ot 
the Chatham Islands specimens that I have seen are less compound, with larger and 
coarser narrower pinnules, corresponding, I presume, with the variety Chuthamicum 
of Mr. Wield (N.Z. Ferns, 81). A curious form gathered by Mr. Hamilton on limestone 
crags at Moteo, near Puketapu, Hawke’s Bay, has the tips of the pinnae largely 
cristate, and the pinnules very irregular in shape. It is the A. Cunninghamii var. 
heterophyllum of Coleniso (Trans. N.Z. Inst. xx (1888) 218). States with the secondary 
thachises somewhat pubescent above, and with rather narrower and more acute pinnules, 
seem to show a marked approach to A. fulvum. 
6. A. fulvum Raoul Choix (1846) 9.—Rhizome long, creeping, clothed 
with brownish subulate scales. Stipes 4-12 in. long, erect, dark reddish- 
brown or almost black, rough with minute projections throughout, more 
or less scaly towards the base. Fronds 6-I5in. long, 3-9 in. broad, 
ovate-deltoid in outline, 2-3-pinnate or rarely in large specimens 4-pinnate
