NortH Is~tanp: Abundant from the North Cape to the Hast Cape, from 
thence rare and local to Cook Strait. Sour Istanp: Nelson—Port Hills, Kirk ! 
Var. Milnei.cKermMAvDEC Isuanps: Abundant, MacGillivray, T. F.C. Sea- 
level to 1000 ft. 
Also in Australia, Norfolk Island, and the Pacific islands as far north as 
Hawaii. A very variable plant. 
2. D. caudata, R&R. Br. Prodr. 151.—Rhizome short, suberect, 
emitting numerous black wiry rootlets. Stipes 2-4in. long, 
slender, black, smooth or nearly so. Fronds numerous, densely 
tufted, 83-12in. long, rarely more, 3—2in. broad, lanceolate, acumi- 
nate or caudate, usually membranous, pale-green, pinnate almost 
to the top, more or less dimorphic; sterile usually shorter than 
the fertile and less erect, often decumbent, sometimes almost 
flaccid; pinnze oblong or linear-oblong, obtuse, sharply serrate. 
Fertile fronds (IESE usually harsher and more rigid, erect; pinn 
4-14 in. long, 4-4 in. broad, narrow-linear, often attenuate, the 
lower ones usually conspicuously auricled at the base, the upper- 
most decurrent and confluent, terminal pinna usually very long, 
caudate. Sori in a single series on each side of the midrib.—

Apparently a common Australian plant, ranging from Cape York to Tas- 
mania. Some of the New Zealand forms approach very close to the preceding 
species; but usually it can be distinguished by the smaller size, by the sterile 
fronds being of a different shape and more flaccid than the fertile, and by the 
narrow fertile pinnz with conspicuously auricled bases. A small variety found 
on the Rimutaka Range, Wellington, is said to have scented fronds, and to have 
been formerly collected by the Maoris for the purpose of mixing with oil to 
anoint the person; but I have never been able to perceive any fragrance. 
Perhaps Polypodiwm pustulatwm has been mistaken for it. I have seen no 
authentic specimens of Colenso’s D. sqwarrosa, and have followed Mr. Baker 
(Ann. Bot. v. (1891) 221) in referring it to D. caudata. 
18s, ASPLENIUM, Linn. 
Rhizome usually short and thick, more rarely long and creeping. 
Fronds tufted at the top of the rhizome or scattered, stipitate, 
pinnate or 2—3-pinnate or decompound, simple and entire in a few 
species not found in New Zealand. Venation variable, free in the 
great mass of the species, including those found in New Zealand. 
Sori linear or oblong, placed upon the veins, more or less oblique 
with respect to the costa, remote from the margin or close to it 
when the frond is much divided. Indusium the same shape as the 
sorus, attached by its side to the vein, straight or rarely curved, flat
