Hab. Matia or Aurora Island, Society Group. 



Rootstock short, erect (4 or more inches high), covered with the base 

 of the old stipes, and throwing out all round strong lateral roots, 

 which support it in an erect position. Stipe 6 to 12 inches long, 

 often as thick as a swan's quill, nearly round, with a single groove m 

 front, which continues up the rhachis; the surface in a recent state 

 concealed with reddish-brown palece, intermingled with matted hairs, 

 which finally disappear. Fronds from one to 4 feet in height, usually 

 erect, and growing in tufts, linear-lanceolate, pinnate ; the young ones 

 having a rusty appearance from the presence of reddish-brown deci- 

 duous scales and matted woolly hairs on both sides. Pinnce numerous, 

 close together, subcoriaceous, oblong-elliptical or lanceolate, sidfalcate, 

 obtuse or slightly acute at the point, and truncate-auriculate at the base, 

 where they are articulated with the rhachis, furnished with a row of 

 white chalky dots at the points of the veins on the upper surface just 

 within the margin. Sort marginal, continuous, usually confined to 

 those pinnse situated on the upper half of the frond. 



The cretaceous intramarginal line of dots on the upper surface of 

 the pinnae, the articulation of the latter with the rhachis, and the 

 habit and general appearance of the whole plant, present a strong 

 resemblance to species of the genus Nephrolepis, Schott.
