POLYPODIACEjE. 261 



sium supra-axillary on the inner edge of a lacinia, somewhat urceolate- 

 cylindrical, the mouth entire. Receptacle slender, and sometimes 

 exserted for half an inch. 



The specimens from the Feejee Islands evidently belong to the 

 variety (3. of Hooker, having their " ultimate and penultimate divi- 

 sions broader and more crowded." The round stipe and main rhachis 

 are not unlike those of T. angustatum, to which also, the outline and 

 colour of its fronds bear no inconsiderable resemblance.

 PI. 8, t. 701, & Spec. Fil. 1, p. 134. 



Hab. Vicinity of the Bay of Islands, New Zealand : in dense and 

 humid forests ; terrestrial. 



Plant cgespitose; the rootstock erect and slightly elongated, crowned 

 by a tuft of nearly erect fronds, 4 to 6 in number, of a deep green 

 colour, 3 or 4 inches long, deltoid-ovate, and bipinnate. Pinnules 

 crowded and imbricated, oblong, cuneate at the base, incisely-lobed j 

 the lacinise entire and acute, or bifid, with a very thick and promi- 

 nent venation. Sori copious. Indusium supra-axillary, free, cylin- 

 drical, with an attenuated base, and an entire scarcely spreading 

 mouth. Receptacle curved, exserted twice or thrice the length of the 

 indusium. Stipe from 3 to 6 inches long, with a few scattered brown 

 scaly hairs at the base; the rhachis perfectly round and smooth. 



This species, so far as we can learn, has only been detected on 

 the northern island of New Zealand. It is very nearly related to 

 the T. rigidwm of Swartz, and differs from that species only by the 

 broader and imbricated pinnules, the larger and more cylindrical 

 indusium, and the round stipe and main rhachis.
