Nephrodium squamigerum, Hook. & Am. Bot. Beech. Voy. p. 106 ? 



Hab. Kaala Mountains, Oahu, Sandwich Islands. Eimeo, Society 

 Islands. Ovolau, Feejee Islands. 



The fronds of this in our collection are flaccid, and, together with 

 the stipe, from 3 to 4 feet high, subtripinnate at the base, upwards 

 bipinnate, with a simply pinnatifid point. Pinnules oblong, obtuse, 

 somewhat falcate, decurrent at the base, pinnatifid. Stipe, rhachis, 

 and costa beneath concealed by numerous pale, chaffy, reticulated, 

 fimbriate scales, appressed to the surface ; the secondary rhachis above 

 with a brownish short pubescence. Sori small, seated about equi- 

 distant between the costseform vein and the margin of the segments, 

 provided with a delicate, reniform, hirsute, fimbriated indusium. 



We have but little doubt that this is the Nephrodium squamigerum 

 of Hooker and Arnott. Our specimens from the Feejee Islands 

 agree more fully with their description than does the single one from 

 the Sandwich Islands, which is rather young; the scales on the 

 rhachis and costa of the latter are more numerous and broader than 

 on the former ; but there is no character that we can discover which 

 would justify us in considering the plants from the three habitats as 

 distinct from each other, or from the species to which we have 

 referred them.

Hab. Northern island of New Zealand : in forests, on the margin of 

 an extinct crater. 



The stipe of this species is almost twice the length of the frond,
