Hab. New Zealand ; in the vicinity of the Bay of Islands. Val- 

 paraiso, Chili. 



Kaulfuss united to Labillardiere's P. rugulosum, which is said to be 

 a native of New Holland, a fern from Chili; in which he is followed 

 by Hooker and Arnott. For ourselves, we had some doubts at first, 

 as to the identity of our New Zealand plant with the one from 

 Chili; but a careful comparison has convinced us that they are one 

 and the same species ; the Chilian plant being only a little more 

 rigid than the New Zealand one, which slight difference may be the 

 result of locality or climate.

 Poli/podium divergens, Willd. Spec. PL 5, p. 209. 



Hab. Organ Mountains, Brazil. 



We doubt very much whether the P. effuswm of Swartz be speci- 

 fically distinct from this. The segments of our plant are perfectly 

 smooth and naked, with a very partial pubescence on the upper side 

 of the stipes, rhachis, and costa. 



32. POLYPODIUM PALLIDUM, Sp. Nov. 



P. ccesjritosum; stipitibus scabro paleaceo ; fronde ampla tripinnata ; pin- 

 nulis lineari-oblongis obtusis adnatis decurrentibus, inferwribus pinna- 

 tifidis, superioribus crenatis, laciniis ovato-oblongis obtusis, margine 

 recurvato, apice dentato, rhacJii costa venisque paleaceo-hirsutis ; venis 

 diclwtomis; soris parvis numerosis juxta marginem positis. 



Hab. Tahiti, Society Islands : in woods near Point Venus. 



Plant ccespitose. Stipes about 2 feet long, of a pale straw-colour, 

 oval and slightly compressed, with two whitish marginal bands in 

 front, which extend to the main rhachis ; the surface rougJiish to the 

 touch, and throughout sparsely furnished with pale, long, slender, fim-
