KEY TO THE EUCALYPTUS TREES, MALLEES AND 

 MARLOCKS, CONTAINING EVERY SPECIES OF THE 

 GENUS KNOWN TO OCCUR IN WESTERN AUS- 

 TRALIA. [JUNE, 1924]. 



This key is intended for the use of foresters and others who may wish to 

 determine species of this difficult genus without resorting to finer botanical dis- 

 tinctions. While a general knowledge of the macroscopic features of a plant 

 will, in most cases, serve to identify the more common species, certain finer differ- 

 ences of floral structure have been used — as necessary distinctions in certain cases — 

 but more often as check features. 



This publication is composed of extracts from Bulletin No. 34, and has been 

 published for field use. Further particulars concerning species may be obtained 

 by reference to the full publication, which contains descriptive and botanical notes 

 concerning all Eucalyptus trees known to be indigenous to Western Australia.
