Pinus excelsa Wall. 



This was introduced by Potts in 1868. Trees measured in 1885 were 

 27 ft. higli. At Greendale P. excelsa grows faster than P. strobus or 

 P. Lambertiana, and is the most promising of the pines having five leaves 

 in a sheath. 



Pinus flexilis James. 



This was introduced about 1903 by the Hon. E. H. Rhodes. Two trees 

 of this species given to me at the time are now each 8 ft. high. 



Pinus koraiensis S. & Z. 



Small plants of this pine introduced in 1906 are growing here, and appear 

 quite hardy.

Pinus Lambertiana Dougl. 



This comes from western America, and grows there to a larger size 

 than any pine in any other part of the world. Some of the oldest and 

 largest trees at Greendale have died, probably through drought. Trees 

 planted here in 1881 are now 23 ft. high, but give no promise of becoming 

 the giants they are in California. 



Pinus Mastersiana Hayata. 



Small trees of this rare species have been raised from seed sent from 

 Formosa two years ago. 



Pinus Montezumae Lamb. 



For plants of this species I am indebted to Mr. Shaw, of the Arnold 

 Arboretum, who spent two years in Mexico studying the pines of that 

 country, and sent me seeds of this and other pines in 1911. Trees 

 growing here are very distinct in appearance, and give promise of successful 

 growth. 



Pinus monticola Dougl. 



Trees of this species growing at Greendale are 8 ft. high, and appear 

 to be capable of growing successfully under local conditions. 



Pinus peuce Grisebach. 



This Macedonia pine was raised from seed sent to me by Dr. Augustine 

 Henry, who in his turn received the seed from King Ferdinand of Bulgaria 

 in 1908. The young plants look healthy and promising. 



Pinus rudis Endl. 



This is considered by Mr. Shaw a variety of P. Montezumae. Plants 

 raised here from seeds sent by Mr. Shaw can be distinguished, while young, 

 from that species by a different shade of green ; otherwise in length of leaf 

 and habit they are the same. 



Pinus strobus L. 



This was early introduced, as it was growing at Governor's Bay, Canter- 

 bury, in 1866, and was reported in 1868 from the Hutt, WeUington. 

 P. strobus is considered a valuable forest-tree in the eastern States of 

 America, but does not seem suitable for general planting here, although 

 trees at Greendale have reached a height of 48 ft.
