EUCALYPTUS TRACHYPHLOIA. 



some cognate Ironbark-trees, all of which however have the stomata isogenous and show a clear 

 line of dehiscence, by which the lid is separated, while the difference of the anthers separate them 

 even sectionally according to Bentham's system. Besides in E. crebra the lid is not depressed, 

 the fruit is not or less contracted at the summit, and the valves are almost terminal. Its real 

 systematic place should be next to E. dichromophloia, from which it can be distinguished in 

 rougher bark, in thinner less elongated leaves of a darker green above and dull paleness beneath 

 (therefore not of equal color on both sides) with recurved edge, in the want of stomata on the 

 upper page of the leaves, in the calyces of less polished smoothness, in smaller fruits with 

 perhaps never or only rarely four valves, and in the absence of any appendage to the fertile seeds. 



Explanation of Analytic Details. — ^1, unespanded flower, the lid partly detached ; 2, longitudinal section 

 of an unexpanded flower ; 3, some stamens in situ ; 4, 5 and 6, front-, side- and back-view of an anther with portion 

 of its filament ; 7, style with stigma ; 8, longitudinal section of a fruit ; 9, transverse section of two fruits ; 10 and 11, 

 fertile and sterile seeds ; 12, portion of a leaf ; all magnified, but to various extent.
