[PRELIMINARY REMARKS. | 
Scarcely a branch of Australian economic botany is in a more 
confused state than that which pertains to the timber of the 
Eucalypts. The genus is perhaps the most difficult one in the 
world, intrinsically, and also because of accidental circumstances, 
7.e., difficulty of obtaining flowers and fruit, and irregular flowering 
seasons ; moreover, the trees vary according to climate and soil to 
such an extent as to render the definition of a species rather 
expansive, and as this difference often extends to the wood, timbers. 
of totally different character are sometimes reckoned under the 
same species.
