794 EUCALYPTS OF NEW SOUTH WALES, 



we would obsei've tliat E. hcemastoma is a smooth-barked tree, 

 and that those rough-barked trees which were thought to show 

 some transition tow^ards E. Sieberiana (as well as to other species) 

 have since been shown to belong to other species. 



The Sydney form is often confused with E. luemastoma, as the 

 young trees often have the appearance of white gum if the butts 

 be not carefully examined. 



If E. Sieberiana lesiYes be crushed in the warm hand they evolve 

 a slight odour of peppermint which is not obser\'able in E. 

 haimastoma. 



In the Flora Australiensis Bentham also draws attention to the 

 affinity between E. Sieberiana and E. hremastoma, and la3^s some 

 stress on the differences between their anthers. We are of 

 opinion that it is difficult, and perhaps impossible, in the present 

 state of our knowledge, to distinguish the two species by means 

 of their anthers. 



As regards the shape of the fruit, our specimens of E. Sieberiana, 

 reputedly from Molong, those of Mr. Howitt from Gippsland, 

 and some from Tasmania (L. Rodwaj^) distinctly are almost 

 hemispheric in form, but they are very distinct from those of E. 

 hcemastoma. 



E. coriacea. — Both Bentham and Mueller compare E. Siebe^'iana 

 and E. coriacea. The closest similarity appears to be in the 

 shape of the fruits. For fruits of E. coriacea see Proc. this Soc. 

 1 895, PI. Liv., figs. 4-6. They are coarser and more fleshy than 

 those of E. Sieberiana ; the coarse, fleshy, spread veins of 

 E. coriacea are also characteristic and quite different froixi those 

 of E. Sieberiana. In addition, E. coriacea is a smooth-barked tree, 

 while E. Sieberiana is rough-barked. 



E. Sieberiana, var. Oxleyensis, var. nov. 



To commemorate the connection of Oxle}^ with Mt. Seaview 

 (where the tree is abundant). 



We now come to a ti'ee undoubtedly connected with E. Sieberiana, 

 and rather extensively distributed in the northern districts. It 

 may perhaps be looked upon as the northern representative of E.
