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



This is one of the most distinct and remarkable species of the 

 genus, and is admirably characterized by A. Richard, in his Botany 

 of the Voyage of the Astrolabe. In the neighbourhood of the Bay 

 of Islands the plant occurs very frequently along the margins of 

 forests, where its tough, wiry, and climbing stems entangle the low 

 bushes and trees, making a passage among them very difficult.

Hab. Bio Janeiro, and Organ Mountains, Brazil. 



In the base of the pinnae of this species a vast variety of forms 

 present themselves, it being either cuneate, subrotund, truncate, cor- 

 date, or auriculate-hastate, and articulated with the petiole ; the sur- 

 face is more or less pubescent according to the nature of the locality, 

 and even on the same individual specimens are found which vary 

 in this respect. The figure given by Raddi, represents the most 

 common form. Perhaps the L. lucens and L. hirfum of Kaulfuss ought 

 to be referred hither.
