HARDY CONIFEROUS TREES 151 



on a healthier and more clothed appearance than 

 is the case when cultivated inland. The speci- 

 mens above referred to were growing in black 

 moory soil. 



P. RADIATA, Don. (Synonyms : P. insignis 

 macrocarpa, Hartweg ; P. insignis of some.) Upper 

 California. 1829. — ^Though this tree bears some 

 resemblance to the better-known P. insignis yet 

 the two are widely different, P. radiata being a 

 much hardier tree when planted in inland situa- 

 tions. The foliage, too, is stouter, shorter, and 

 of a duller green, while the cones are much larger 

 and more persistent than those of P. insignis. 



When well grown it is a distinct and beautiful 

 tree with a massive, well-rounded top and usually 

 clothed with branches to the ground - level, the 

 diameter of branch-spread equalling the height 

 in many of the home-grown specimens. 



The largest P. radiata that I have measured is 

 growing on the lawn in Cooper's Hill Park, which 

 is 65 feet high with a branch-spread of 63 feet and 

 a stem-girth of 12 feet 7 inches at a yard from the 

 ground. The cones are produced in great abund- 

 ance usually in circles around the branches as 

 well as on the stem where they persist for many 

 years. As many as twenty-five whorls of cones 

 may be seen on some of the branches. 



Another fine specimen is growing on a hillside on 

 the Churchhill Estate in North Ireland, and it is 

 remarkable how like in appearance is this tree and 

 the one at Cooper's Hill. The soil on which both 

 trees are growing is gravelly and the situation 

 elevated. When most of the established trees of 

 P. insignis along the coast were injured or killed
