Adams. — Species of Pinus ?iow growing in New Zealand. 223 



Pinus Torreyana Parry. 



This is quite unlike any other five-leaved pine, the leaves being long 

 and much stouter, reminding one of some forms of P. Jeffreyi or P. Conlteri, 

 but the tree has a more open head. The species was introduced here in 1870, 

 and has grown rapidly. The largest tree in the Christchurch Botanic Gardens 

 is 90 ft. high, and there is a large one also in the public gardens, Timaru. 

 These heights are much greater than the floras give, but the tree is 

 unlike any other in its appearance, so that there can be no doubt as to 

 its identity. 



In addition to the pines cited above, plants have been raised here of 

 pines under the following numbers — 1370, 1378, 1390, and 1396— from 

 seeds collected by Mr. E. H. Wilson in western China, and kindly sent to 

 me by Professor Sargent, of the Arnold Arboretum. 



Articles on the introduction and growth of pines will be found in the 

 " Transactions of the New Zealand Institute," as follows : — Vol. 1 (1869) : 

 Here Mr. Ludlam mentions seventeen species as growing in his pinetum ; no 

 heights are given. Vol. 4 (1872), p. 368, in a paper read before the Wel- 

 lington Institute, Mr. Pharazyn gives the height of seven species of pines 

 growing in 1871. In vol. 12 (1880), p. 357, there is a list of trees given 

 that were planted in 1866, and their height; the list contains eight species. 

 In vol. 29 (1897) a list of twenty-six species growing at Taita, Hutt, is 

 given, with their height in 1896. 



In the " New Zealand Country Journal," vol. 3, p. 37, will be found 

 a list of the pines growing at Ohinitahi, Governor's Bay. The list contains 

 twenty-one species of pines, the date of planting, their rate of growth, 

 and much other valuable information. In discussing some peculiarities of 

 Pinus tuhercidata, Potts incidentally mentions that his plants were raised 

 from seeds imported by the New Zealand Government and distributed 

 through the Geological Survey Department. 



In an appendix to the Journals of the House of Representatives, 1877, 

 an account is given of a number of plantations in New Zealand, mostly 

 of eucalypts, but twelve species of pines are mentioned as having been 

 observed growing in them.

 Author at Greendale, Canterbury, New Zealand. 



By T. W. Adams. 



[Sead before the Philosophical Institute oj Canterbury, 7th July, 1915.] 



The collection contained the acorns of thirty species, and the leaves of 

 sixty-three species or varieties, all of which are grown by the author. 

 The species were as follows : — 



Quercus acuta Thunb. 



The leaves are more suggestive of a laurel than an oak. It is quite 

 hardy at Greendale. Planted, 1893. Height, 5 ft. A native of Japan.
