OBSERVATIONS ON THE EUCALYPTS OF NEW 



SOUTH WALES. 



Part III. 



By Henry Deane, M.A., F.L.S., and J. H. Maiden, F.L.S. 



(Plates xxix.-xxxiii.) 



Eucalyptus h^mastoma, Sm. 



Introductory. — The species is found in two principal varieties, — 

 a coarse form (the type), and a slender one, the latter with small 

 flowers and fruits, and known as variety micrantha in consequence. 



As regards the type, the leaves, flowers and fruits are alike 

 larger, and the leaves thicker, but, as a rule, the tree itself does 

 not attain the magnitude of its vai'iety. 



With Bentham's amplified description of the species as given 

 in B. Fl. iii. 2 1 2, we in the main agree, so that it will only be 

 necessary to add a few notes. 



Vernacular names. — ■"' White Gum " is the commonest and most 

 appropriate name for this species. As regards the vernacular 

 names in the Flora Australiensis, Cunningham's name of "Black- 

 butt " is a misnomer and has probabl}^ arisen from confusion of 

 this species with the " Mountain Ash " ( E. Sieberiana), and the 

 name of " Mountain Ash " for E. hcHmastoma has probably arisen 

 through too close reliance upon herbarium specimens, those of U. 

 hannastoina and E. Sieheriana being frequently ditficult to dis- 

 criminate unless complete material be available. The resemblances 

 of the two species will be again referred to when E. Sitberiana is 

 dealt with. 



Bark. — Smooth, with a few ribbony flakes near the butt. 



The species referred to in the following paragraph in the 

 Eucalyptographia is most pi'obably our E. fastigiata {Proc. Linn. 

 Soc. JV.S. W.), and we may mention that we have never seen true 

 E. hcemastoma other than a white or at the most a ribbony gum.
