The Pines of Australia. 



Hustralian ConifercB, 



INTRODUCTION. 



The Gymnosperms find their greatest representation in Australia and Tasmania 

 in the Natural Order Coniferae, — one of the most widely distributed botanical 

 divisions scattered over the earth — being represented in both the Northern and 

 Southern Hemispheres, although less so in the latter, and of the thirty-two genera 

 described in Bentham and Hooker's " Genera Plantarum," eleven are found in 

 Australia and Tasmania, viz. : — 



TRIBE I. — Cupressinece. 

 *i. Callitris. 



2. Actinostrohus. 



3. Fitzroya. 



TRIBE II. — TaxodiecB. 

 II. Athrotaxis. 



TRIBE III.—TaxecB. 



16. Phyllodadus. 



17. Dacrydium. 



18. Pherosphcsra. 



TRIBE IV.—Podocarpecs. 



ig. Microcachrys. 

 21. Podocarpus. 



TRIBE V. — AraucariecB. 



23. Agathis. 



24. Araucaria. 



In all, six tribes are listed by those authors, and it will be seen that five 

 of these are found in the Australian and Tasmanian Flora. 



* These numbers are those of Bentham and Hooker, loc. cit., and give the systematic sequence of the 

 genera in that work.
