Adams. — Species of Pinus now groivmg in Sew Zealand. 221 



Pinus scopulorum Lemmon. 



By many authorities this is considered a variety of P. ponderosa, but trees 

 growing here more resemble some forms of P. Jeffreyi. The rate of growth 

 is much slower than in P. ponderosa. 



Pinus taeda L. 



This grows well in New Zealand. It is said to have been introduced by 

 the late Mr. Rolleston while Superintendent of the Canterbury Province, 

 hut I know of no trees planted so early. Trees here are 20 ft. high. 



Pinus teocote Cham. & Schlecht. 



Small plants of this Mexican pine are growing at Greendale, and will 

 probably prove to be hardy. 



Pinus tuberculata Gord. 



This is a fast-growing pine in New Zealand, and also remarkable for 

 retaining its cones on the tree unopened for many years, while occasionally 

 cones may be seen almost entirely enveloped in the trunk of the tree. 

 Trees here planted in 1880 have still all their cones on them, not a seed 

 having been released, and cones twenty years old when broken open give 

 forth seed that readily germinates. Introduced about 1869. 



Pinus yunnanensis Franchet. 



This species was discovered in western China by the Abbe Delavay, 

 and first described in 1899. Through the kindness of Professor C. Sargent, 

 of the Arnold Arboretum, seeds were sent to me in 1909, and a goodly number 

 of plants were raised. These have been planted in many places in New 

 Zealand, and everywhere are maldng good growth. Trees planted at Broad- 

 wood, Hokianga, are now bearing cones. This new pine is one of the most 

 beautiful, if not the most beautiful, yet introduced, and will be very much 

 admired for its rapid growth and fine form when better known. 



(3.) Trees whose Leaves are usually Five in a Sheath. 



Pinus aristata Engelm. 



This is one of the American alpine pines ; it is of very distinct appear- 

 ance while young. Trees here are 4 ft. high, and growing slowly but 

 quite successfully. 



Pinus Armandi Franchet. 



This comes from western China. Seeds were received from Professor 

 C. Sargent in 1909, and plants raised from them are now 3 ft. 6 in. high. 

 It appears to be related to the Korean pine (P. koraiensis S. & Z.) in leaf 

 and cones, two of which I received from Kew, though distinct, reminding 

 one of that species. 



Pinus cembra L. 



This European mountain-pine grows slowly here. At Greendale the 

 Siberian form grows much better than the Swiss form.
