EUCALYPTUS DIVEESICOLOR. 



Drummond's collections contain this species under jSTos. 39 and 59. 



E. diversicolor among West Australian species bears some similarity to E. marginata, but the 

 leaves are still paler beneath, the lid is almost constantly shorter, particularly so in proportion to 

 the tube of the calyx, the anthers are not broader than long and their glandular protuberance is 

 much larger, the fruit is longer in comparison to its width, the valves are also longer and the 

 seeds very much smaller ; besides bark and wood are totally different. 



The Karri-tree cannot in nature be confused with E. patens, the Blackbutt-tree of West- 

 Australia, on account of the greatly persistent and rough bark of the latter, which has besides 

 more curved leaves of almost equal coloration on both sides, the anther-gland very faint, the fruit- 

 rim narrower, the valvular portion of the fruit at first flat and consisting usually of four rarely 

 five pieces, the seeds larger. 



What as E. goniantha is mentioned by Bentham from the Frankland-River belongs to 

 E. diversicolor. 



The diametric measurement of the woody fibre, and the proportionate number of the me- 

 dullary rays and vascular tubes, as contrasted with their copiousness in some other kinds of 

 Eucalyptus-woods, is set forth in the following columns, whereby some idea of the relative density 

 of the timber and the closeness of the woody texture may be obtained.
