Art. LII. — On the Xew Zealand Species of Phyllocladus. 

 By T. Kirk, F.L.S. 

 [Read before the Wellington Philosophical Society, 11th November, 1877.] 

 With the exception of the kauri the celery-leaved j)iiies are the most 

 attractive members of our indigenous coniferse ; their striking appearance 

 at once arrests the attention of the planter, while the singular structure of 

 their foliaceous appendages gives them special interest in the eyes of the 

 botanist. Only five species are known, three of which are found in New 

 Zealand, in many localities forming a marked featu.re in the vegetation. Of 

 the remaining species one is confined to the lofty mountains of Borneo, 

 another which is closely allied to, if not identical with, the New Zealand P. 

 alpina, is found in Tasmania, and, I believe, also in New Caledonia. 



The species vary from dwarf alpine shrubs as P. alpina to handsome 

 trees as P. trichovianoides, seventy feet in height, with a trunk from two to 

 three feet in diameter, and affording timber of great strength and durability. 

 AU the species have the branches more or less arranged in whorls. P. 

 ylauca is invariably dioecious, P. trichomanoides invariably monoecious, P. 

 alpina must be considered monoecious also, but there is reason to believe 

 that this species shows a tendency to assume a dioecious character ; this, 

 however, has not been proved.
