reduced to short triangular lobes, so that the frond is narrow-linear in out- 
line. Veins obscure, simple or forked. Sori oblong or rounded, usually 
one at the base of each segment of the pinnae, more rarely 2-4 to a segment.—

NortH AND Soutrn Isnanps, Stewart Is~tAnp, CHATHAM ISLANDS, AUCKLAND 
AND CAMPBELL Istanps: From the North Cape southwards, abundant in forests on 
the trunks of trees, more rarely on rocks. Sea-level to 3500 ft. 
Also in Tasmania and. Victoria. 
3.-P. dictyopteris Metten. in. Ann. Sci. Nat. xv (1861) 72.—Rhizome 
small, short, knot-like, densely clothed with brownish lanceolate scales, 
emitting woolly rootlets, some of which creep and produce new tults of 
fronds. Fronds tufted at the top of the rhizome, 4-12 in. long, 3—-?in. 
broad, lanceolate or linear-lanceolate, acuminate, very gradually narrowed 
to the base or to a short stipes, quite entire, bright-green, rather fleshy but 
hardly coriaceous, quite glabrous; midrib stout, evident. Veins hidden 
in the substance of the frond, anastomosing, forming elongated hexagonal 
areoles without included free veinlets. Sori large, broadly oblong or rounded, 
prominent, rather far apart, in a single row on each side of the frond, nearer 
the midrib than the margin.—P. Cunninghamii Hook. Sp. Fil. v (1864) 58 ;

Norra IsnaAnp: In forests from the North Cape to Cook Strait, not uncommon, 
usually on the trunks of trees or on rocks. Sourn Istanp: Nelson—Maitai Valley, 
T. F.C. Marlborough—Buchanan. Canterbury—Akaroa, Raoul. Sea-level to 2500 ft. 
Also in the New Hebrides. I have seen no specimens from the south of Nelson. 
Mr. Phillips Turner sends me a curious crested form obtained near Wellington. 
4.P>pustulatum Forst. f. Prodr. (1786) n. 436.—Rhizome very long, 
much branched, climbing up the trunks of trees or over rocks, everywhere 
clothed with squarrose linear-subulate dark-brown scales. Stipites scattered 
along the rhizome, 2-4 in. long, firm, slender, glabrous. Fronds very vari- 
able in size and outline, dark-green, thin and membranous, quite glabrous, 
sometimes 3-9 in. long, 4-2 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, 
1_1in,. broad, straight or faleate. Veins not very distinct, anastomosing, 
forming large irregular areoles with included free veinlets. Sori rather 
small, distant, broadly oblong or rounded, forming a row parallel with the 
margin and just within it, sunk in a shallow cavity of the frond and thus 
forming a pustule on the upper surface.—A. Cunn. Precur. (1836) n. 175 ;
