DiIsTRIBUTION OF THE GENUS. 
See under Pseudopanax ferox, p. 35, ante. 
DISTRIBUTION OF THE SPECIES. 
This species is only found in New Zealand, but the form with trifoliolate 
leaves is practically restricted to the Auckland District and the northern part of 
Hawke’s Bay. Mr. J. Buchanan states that it occurs in Otago, but gives no 
locality: it does not appear to have been found in that district of late years. 
Var. unifoliolata occurs in forest districts from the southern parts of Auck- 
land and Hawke’s Bay to Stewart Island, often in great abundance.
