Kirk. — On a revised Arrangement of N.Z. Species of Dacrydium. 387 



This species is the yellow silver pine of Westlaud, where it is highly 

 valued for its durability. It is occasionally utilized on the Thames Gold- 

 field.

T. Kirk, MS. ; Hook, fil., Icones Plantarum, t. 1218. 



A dioecious tree 40-50 feet high, trunk 1^-2^ feet in diameter, bark 

 whitish, branches slender. Leaves of seedling plants terete, of early 

 branches sub-terete, or trigonous, or subulate, decurrent, erecto-patent, 

 compressed, \-\ inch long. Fruiting branchlets very slender, -^Vnrs" iiich 

 in diameter ; leaves rigid, broadly triangular, compressed, carinate, slightly 

 imbricate, obtuse. Male catkins terminal, solitary, oblong, x^g— rV ^^^^^^^ long. 

 Nuts (immature) solitary, or 1-3, yV^xtr inch long, obtuse, not compressed. 



North Island : Whangaroa — Hector ! ; Great Barrier Island — J. Spring- 

 all and T. Kirk (1871). 



South Island : Greymouth to Okarita (in all probability extending 

 northward to the mouth of the Buller and southwards to Martin Bay) ; 

 not observed further inland than the Ahaura plain. 



In the young state this species closely resembles the preceding, but the 

 leaves are slightly trigonous ; the minute leaves of the fruiting branches, 

 and the small obtuse nuts, which are usually two in number, distinguish the 

 mature state from all other members of this section. The wood is white, 

 dense, and extremely durable. 



My first knowledge of this plant was from dried specimens in the young 

 state received from Dr. Hector in 1869, and collected by him at Whangaroa. 

 In 1871, Mr. Springall and myself collected young plants on one of the 

 high ranges in the interior of the Great Barrier Island, but owing to the 

 approach of night we were unable to search for trees. It was only on 

 visiting the west coast of the South Island in January, 1877, that I was 

 able to identify the young state of the northern plant with the present 

 species, which, although long valued for the durability of its timber, and 

 forming an article of export under the name of Westland pine, or white 

 silver pine, had not come under the observation of botanists. 



The early leaves have some resemblance to those of Podocarp)us dacry- 

 dioides, but the plant is stouter, with longer and flexuous branches.
