primary ones irregular, enclosing between them several areoles 
with free included veinlets. Sori numerous, large, orbicular, form- 
ing a single row on each side of the midrib, medial or rather nearer 
the margin than the midrib.—dA. Cunn. Precur. n. 174; Raoul,

usually on trees or rocks, but sometimes on the ground. Sea-level to 3000 ft. 
Found also in Norfolk Island, Lord Howe Island, Australia, and Tasmania, 
and very closely allied to the tropical P. Phymatodes, Linn. 
10. P. novee-zealandiz, Bak. in Hook. Ic. Plant. t. 1674.— 
Rhizome long, stout, woody, as thick as the finger, densely clothed 
with large tawny ovate-lanceolate scales. Stipes 6-12 in. long, 
firm, erect, pale-brown, shining, quite naked. Fronds scattered 
along the rhizome, large, 1-4 ft. long, 6-14in. broad, oblong- 
lanceolate, acuminate, thinly coriaceous, dark-green, quite glabrous, 
deeply pinnatifid or almost pinnate at the base; rhachis narrowly 
winged. Segments (or pinne) 8-20 pairs, opposite or nearly so, 
ascending, 4-8 in. long, about 4in. broad, linear-lanceolate, acumi- 
nate, quite entire or obscurely sinuate, the lower ones sometimes 
narrowed towards the base. Veins indistinct, copiously anasto- 
mosing; areoles rather large with included free veinlets. Sori 
large, globose, forming a single row on each side of the midrib, 
rather nearer the margin than the midrib.—Ann. Bot. v. (1891) 479;

Waikaremoana, A. Hamilton! Waimarino Forest, R. Curtis! forest to the 
west of Ruapehu, H. C. Field ! Usually on logs or climbing up trees, rarely 
on the ground. 1500-3000 ft. 
Apparently confined to the forest country in the central portions of the 
North Island. Closely allied to P. Billardieri, but the rhizome is much stouter, 
and densely clothed with shaggy spreading scales; the fronds are larger, often 
4 ft. long, and more deeply pinnatifid ; the segments are more numerous, longer 
and narrower; the venation is not so distinct, and the texture thinner. There 
is also no tendency to the polymorphism of the fronds so noticeable in both 
P, Billardieri and P. pustulatum, and simple fronds are apparently unknown. 
23. NOTHOCHLAINA, R. Br. 
Rhizome short and tufted or long and creeping. Fronds usually 
small, erect, pinnate or 2-3-pinnate; under-surface more or less 
densely scaly or woolly or coated with white powder; texture 
coriaceous. Veins free, forked, not anastomosing. Sori marginal, 
oblong or rounded, terminating the veins, at first distinct, but soon
