Dacrydium, 



51. A strong botanical resemblance of tins Pine was found to those of the same 

 genus growing in the Pacific Islands. 



5^. The principal constituent of the leaf oil is a terpene, which appears not to 

 have been pre\-iously recorded. 



53. The methyl-ether of eugenol occurs in the leaf oil of this species. 



54. The steam-distilled oil from the timber of this tree, and to which the odour of 



the wood is due, is composed mostly of the methyl-ether of eugenol. 



Pherosphaera. 



55. .\ further extension of the geographical range of this genus in New South 



\\'ales is shown. 



56. The principa' constituent of the oil of this delicate prostrate Conifer is pinene. 



57. The sesquiterpene cadinene is also a pronounced constituent of the oil. 



Phyllocladus. 



58. The morphological, anatomical, chemical, and foliaceous character of the 



Phylloclades are fully detailed, and as the leaves are quite degenerate organs 

 in the species, their functions are thus performed by proxy as it were. 



59. The substance of greatest interest occurring in the !eaf (phylloclade) oil of this 



tree is a solid, readily crystallisable diterpene; it is dextro-rotatory, and 

 melts at 95° C. The name Phyllocladene is proposed for it. 



60. Pinene occurs in quantit}' in the leaf (phylloclade) oil and practically in a 



pure condition. 



61. The bark contains both tannin and a glucoside having d3^eing properties. 



Podocarpus. 



62. The microscopical character of this timber differs from that of Araucaria, or 



of Agathis, but resembles more generally that of Callitris. Macroscopically 

 it differs from them all. 



General. 



63. A botanical survey of the Pines of New South Wales is now given for the first 



time.
