NOTES ON THE NATIVE FLORA OF N. S. WALES_, ix., 



mation along the Main Divide, extending from Cassilis to southern 

 New England, is of too basic a character to support the growth of 

 this particular Peppermint. The curious distribution of this tree 

 in the north, furnishes an interesting subject for investigation, 

 which might be considered in conjunction with the study of local 

 physiographic problems, and climatic changes. 



E. C'amhagei was found unexpectedly on Mount Lindsay, extend- 

 ing from about the 3,500 feet level to nearly 4,900 feet, or practi- 

 cally on the summit. In its distribution, this species is not unlike 

 E. dives, favouring the western side of the Main Divide and extend- 

 ing into Victoria, but descending to lower levels, and sometimes 

 growing on more basic formations. Its most northern limit pre- 

 viously known to me was near Murrurundi, and close to the Liver- 

 pool Range, where it is growing on basaltic formation at an eleva- 

 tion of about 1,500 feet; but I have recently found it at Curra- 

 bubula, on Carboniferous formation, at an altitude of 2,500-2,900 

 feet. It is remarkable that, so far, this tree has not been recorded 

 from New England, while, however, it has found its way to the 

 Nandewars, and should be looked for in the Nundle Swamp Oak 

 district, on the southern portion of New England. (For previous 

 remarks concerning this species, see these Proceedings for 1902, 

 p. 199.) 



E. Andrewsi and E. nova-anglica were found at about the 

 3,000 feet level, the former on the acid, volcanic agglomerate 

 formation, and the latter on the alluvial flats near the 

 Horton River. The occurrence of these two species in this 

 locality is of interest, as neither has been recorded south of the 

 Hunter Valley, and both are regarded as typical New England 

 trees. They have, however, found their way westward to the Nan- 

 dewars, although some of the intervening country is lower than 

 the elevations at which they usually flourish. Curiously they have 

 here met with two southern Eucalypts which do not occur on 

 northern New England, viz., E. dives and E. Cambagei, although 

 owing to considerations of soil and moisture requirements they do 

 not actually associate with them, though only separated by a mile 

 or so. (For previous remarks concerning E. Andrewsi and E. nova- 

 anglica, see these Proceedings for 1904, pp. 791, 795.)
