RANGE. 



So far it appears to be confined to a small area of the coast districts of the 

 comities of Cumberland and Northumberland, at no great distance south and north of 

 Sydney. X.S.W. 



The following are the localities : — 



Between Stan-well Park and Otford, large spreading tree with slightly glaucous 

 undulate adult leaves (W.F.B.) ; Oatley and National Park (J. H. Camfield, April, 1901 ) ; 

 the fruits from Oatley are slightly larger and thicker than the type ; Gladesville (H. 

 Deane, June. 1886); Cedar Gully, Cowan; tall, straight trees, up to 100 feet high 

 and 2 feet in diameter, growing in association with E. agglomerata on rich clay soil 

 (Bott, Shiress arid Blakely); at the foot of Mt. Penang and along the old Penang-road 

 for some distance ; also in Kendall's Glen, which is on the left of the Penang-road going 

 west from Gosford; trees 50 to over 100 feet high, somewhat like E. pilularis in 

 appearance, with straight boles covered with a rather thick, grey Peppermint-like 

 bark extending to the base of the large branches on moderately small trees, and on old 

 trees extending to the small branches. The top portion of very young saplings is some- 

 what prainose Uke those of E. Sieberiana, and the leaves are large, slightly glaucous, 

 and distinctly undulate. At one spot it is ecologically associated with E. paniculata, 

 E. pilularis, E. saligna, and Angopliora intermedia. Very old trees of E. Bottii are 

 markedly like old tree of A. intermedia, both in general appearance and in cortical 

 characters. The rough, grey bark of the former persists well out on the branches like 

 the bark of the Angophora (W.F.B. , H. Bott, and D. W. C. Shiress) ; between Teralba 

 and Fassifern, also about one mile south of Awaba (W.F.B.) ; Narara, on the edge of 

 the brush (W.F.B, D.W.C.S, and A. Murphy). 



AFFINITIES. 



1. With E. piperita Sm. 



It is quite obvious that there are imperceptible gradations between E. Bottii 

 and E. piperita and its allies, but the main difference between them is in the superior 

 size, and more shaft-like habit of E. Bottii with its relatively better timber; in the 

 broader subglaucous juvenile and intermediate leaves, as compared with the very thin 

 light green leaves with their pale undersirrface of E. piperita ; and in the slightly pruinose
