EUCALYPTUS PEUINOSA. 



melanophloia dilates slightly over the width of the style, and the fruit (so far as I have become 

 aware) gets never so large as that of E. pruinosa, it being especially shorter and also distinctly 

 contracted at the edge. 



Among trees with roundish sessile greyish opposite leaves only to E. pulverulenta need be 

 alluded here in reference to their distinguishing marks ; but it has its umbels solitary and axillary, 

 its anthers elongated and opening with longer slits and its fruits flat- or convex-rimmed. 



The connate leaves, smaller flowers, shorter lid, longer anther-slits and most particularly the 

 sharply triangular seeds, surrounded by a diaphanous membrane, distinguish E. gamophylla 

 readily from E. pruinosa. 



The very pale bloom of the foliage, which suggested the specific name, is chemically of waxy 

 nature. 



E. pruinosa might prove a good tree for fuel and perhaps also for technical purposes in 

 any tropical country : it would at all events be as adapted to an equinoctial clime as E. 

 tereticornis, E. resinifera, E. acmenoides and E. Baileyana have shown themselves suited to as 

 well sandy as swampy grounds in Guinea, as observed by Dr. J. W. Eowland. The frequency 

 of this tree in its wide natural region indicates the facility of its dissemination also. 



EXPLANATION OF ANALYTIC DETAILS. 1, an unexpanded flower, the lid lifted ; 2, longitudinal section of 

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

 filament ; 6, style and stigma ; 7 and 8, longitudinal and transverse section of fruit ; 9 and 10, sterile and fertile 

 seeds ; 11, portion of a leaf; all figures more or less magnified.
