The Eucalypts between Trundle and Parkes were represented 

 by E. populifolia, E. WooUsiana, E. melliodora, E. sideroxylon 

 (24 m.), E. conica (23 m.), E. tereticornis (21 m.), E. tereticornis, 

 var. dealhata^ E. sideroxylon (one tjree with red flowers in June ; 

 15 m.), E. hemiphloiavar. albens (White Box), E. conica (10 m.), 

 E. melliodora (7 m.), E. Woollsiana, E. populifolia (2 m.), 

 E. Woollsiana and E. melliodora. 



The trees of E. tereticornis near the 22-inile post were the first 

 typical ones seen in coming from Bourke. From this point 

 easterly the species is not uncommon on the lowlands, the variety 

 dealbata taking the hills {vide Part ii.). 



E. populifolia has been seen practically all the way, but it 

 ceases about six miles westerly from Parkes, and easterly of a 

 line joining Parkes, Forbes and Temora the species is not found. 

 Nor have I seen it east of a line joining Parkes and Dubbo. 



Towards Parkes the leaves of E. Woollsiana are in many cases 

 much broader than in the Nymagee district. 



E. hemiphloia, var. albens, is the common White Box of the 

 western slopes. It seems to prefer a climate between the extreme 

 heat of the plains and the extreme cold of the mountains, so 

 that its distribution, though extending very far north and south, 

 is much more limited east and west. It practically extends all 

 along the western side of the Great Dividing Range, but rarely 

 is to be found on the higher parts of it excepting towards the 

 north. It comes eastward among the mountains by following the 

 valleys of such rivers as the Macquarie, Turon, Lachlan and 

 Abercrombie, but only crossing from one to the other where the 

 intervening hills are low. This is another of those western forms 

 that comes across the Liverpool Range on to the coastal area near 

 Scone, and is plentiful on the upper Hunter. As previously 

 mentioned (Part iii.), its flowers are rich in honey, and on 

 Moonan Brook (a tributary of the Hunter), the bees during the 

 autumn obtain their supply chiefly from this species. As a line 

 from Dubbo through Forbes to Temora roughly marks the eastern 

 limit of E. populifolia, so a line from about Narromine through 

 Temora to Corowa on the Murray approximately denotes the 

 western margin of E. hemiphloia, var. albens. In its most western
