LIST OF NATURALIZED PLANTS 



REPORTED TO OCCUR IN NEW ZEALAND, 



WITH THE DISTRIBUTION OF THOSE FOUND IN THE PROVINCE OF AUCKLAND SHOWN 



IN DETAIL. 



PiANUNCULACEiE. 



Ranunculus acris, L., Europe, P., 2-3-4-6, t Ace. Den. Pas. 



,, repens, L., Europe, P., 3-4, Ace. Den. Pas. Inu. 



,, parvijiorus, L., v. australis. Possibly introduced, according to 

 Dr. Hooker. It has, however, the appearance of a truly indigenous 

 plant, and as such it seems best to regard it. 



Papaverace^e. 



Papaver Rhceas, L., Europe, A., 1, Una Col. Via. Local. I have observed 

 this plant in a solitary locality at the north-western extremity of the 

 island ; it may, however, be expected to occur commonly as an agrestal 

 plant.
