3—4 m longae, 70—90 cm latae, bi-tripinnatae, subcoriaceae v. fere 
membranaceae, flaecidae. Stipites rhachidesque graciles, basi squamis 
fuscis lineariis vestiti, supra alte canaliculati, virides, lana flavofusca et 
squamis lineariis dense vestiti, subtus subasperi, fusci, lana decidua et 
squamis membranaceis, Pinnae 35—45 cm longae, 12—14 em latae, ob- 
longo-lanceolatae, acutae; pinnulae 60—70 mm longae, 15—18 mm latae, 
lineario-oblongae, acutae, profunde pinnatifidae; segmentae, 8—9 mm 
longae, 3 mm latae, oblongae, falcatae, obtusae, integrae v. crenulatae. 
Sori copiosi, parvi, 0,5—0,6 mm lati. Indusium membranaceum, fimbriato- 
lacerum persistens. — A magnificent species, with a tall, slender trunk, 
15—20 m high; the base composed of aerial rootlets, reaching 3 m or 
4 m from the ground, where it may be 1--2 m in diameter. Fronds 
fall away when they wither, leaving a clean scar; thus the upper portion 
of the trunk is comparatively smooth. The diameter, 1,5 m from the 
top of a trunk 11 m tall, was only 11 em. — Fronds numerous, the 
stipes forming an angle of 100°—120° with the top of the trunk, 3—4 m 
long, 70—90 cm broad, 2—3-pinnate, subcoriaceous or almost mem- 
branous, flaccid, dull green above, paler beneath. Stipes slender, base 
clothed above and on the sides with copious linear brown scales; stipes, 
rhachides, and costae deeply grooved above and slightly on each side, 
green above, brown below, upper surfaces densely covered with yello- 
wish-brown wool intermixed with small linear scales, undersurfaces 
slightly asperous, sparingly covered with yellowish-brown deciduous wool 
and membranous scales. — Primary pinnae 35—45 cm long, 12—14 cm 
broad, oblong-lanceolate, acute or acuminate; secondary pinnae 60— 
70 mm long, 15—18 mm broad, linear-oblong, acute or acuminate, obs- 
curely faleate, deeply pinnatifid, Segments 8—9 mm long, 3 mm broad, 
oblong, faleate, obtuse or subacute, entire, or finely crenulate, or the 
fertile segments lobulate; costules scaly pubescent; veins forked, free. 
— Sori copious, small, 0,5—0,6 mm in diameter, nearer the costule than 
. the margin. Indusium membranous, splitting irregularly, persistent. — 
Kermadec Islands: Forest (chiefly in wet forest) Sunday Island. — 
Endemic. Apparently closely allied to some Polynesian species.
