Polypodium. | FILICES. 1013: 
Nortu Istanp: In forests from the North Cape to Cook Strait, not 
uncommon, usually on the trunks of trees or on rocks. SourH ISLAND: 
Nelson—Maitai Valley, 7. #7. C. Marlborough—Buchanan. Canteroury— 
Akaroa, Raouwl. Sea-level to 2500 ft. 
Also in the New Hebrides. I have seen no specimens from the south of 
Nelson. 
8. P. pustulatum, Yorst. Prodr. n. 436.—Rhizome very long, 
much branched, climbing up the trunks of trees or over rocks, every- 
where clothed with squarrose linear-subulate dark-brown scales. 
Stipites scattered along the rhizome, 2-4 in. long, firm, slender, gla- 
brous. Fronds very variable in size and outline, dark-green, thin and 
membranous, quite glabrous, sometimes 8-9 in. long, 1-2 in. broad, 
linear-lanceolate, acuminate, gradually narrowed into the stipes, 
quite entire ; at other times 6-18 in. long, 2-6 in. broad, cut down to 
a broadly winged rhachis into few or many linear-lanceolate 
acuminate segments ; segments rather distant, 1-3 in. long, +1in. 
broad, straight or falcate. Veins not very distinct, anastomosing, 
forming large irregular areoles with included free veinlets. Sori 
rather small, distant, broadly oblong or rounded, forming a row 
paraliel with the margin and just within it, sunk in a shallow 
cavity of the frond and thus forming a pustule on the upper sur- 
face.—A. Cunn. Precur. n. 175; Raoul, Choix, 37; Hook. Sp. Fri.

NortH AND SoutH ISLANDS, CHATHAM IsLANDS: Abundant in woods from 
the North Cape to Nelson, Marlborough, and Westland, from thence less common 
to the south of Otago. Sea-level to 2500 ft. 
Found also in eastern Australia, from Queensland to Victoria, and in 
Norfolk Island. The fronds are fragrant when freshly dried, and were formerly 
used by the Maoris for scenting oil for applying to the person. Mr. Carruthers 
(Fl. Vitiensis, 369) considers that this is Forster's P. scandens, and that his 
P. pustulatum is the same as P. Billaraiert. 
9. P. Billardieri, &. Br. Prodr. 147.—Rhizome long, stout, 
creeping, often glaucous, clothed with appressed ovate-lanceolate 
acuminate scales, which are dark-brown or almost black with 
usually a pale scarious margin. Stipes jointed on to the rhizome, 
2-8 in. long, stout, firm, erect, smooth and glossy, quite naked. 
Fronds numerous, scattered along the rhizome, bright-green, coria- 
ceous, quite glabrous, polymorphous ; sometimes 3-9 in. long, 
4-2 in. broad, lanceolate or ovate-lanceolate, entire; at other times 
6-18in. long, 3-9in. broad, deeply pinnatifid. Segments varying 
in number from 1 to 12 on a side, 1-5in. long, 4-1+in. broad, 
oblong-lanceolate or linear, usually acuminate, confluent at the 
base with the broadly winged rhachis. Veins conspicuous, the
