PINACEAE. 
So many species of Coniferae are now being planted for forestry purposes in New 
Zealand that I cannot doubt that many species additional to the following are 
spontaneously increasing. Whether they are also intruding into fresh ground after the 
fashion of truly naturalized plants I am not so certain. 
Pinus pinaster Ait.'Hort. Kew, ed. 1, iii, 367 (P. maritima Lam.). Reproduces itself 
from the seeds of planted trees, and is now to be seen in many localities in both 
the North and South Islands. (Mediterranean region.)

reproducing itself in many localities. (California, coast ranges between San Fran- 
cisco and Monterey. )
