690 SOME NEW SPECIES OF EUCALYPTUS, 



Hob. — Richmond River District (W. Bauerlen); Cook's River 

 Sydney (H. G. Smith). 



From E. Wilkinsouiana, Baker, and E. macrorhyncha, F.v.M., 

 it differs in fruits, timber and chemical constituents of the oil. 

 From the Stringybark, E. umbra, Baker, of this paper it differs 

 in the shape of the sucker leaves and chemical constituents 

 of the oil, although the immature fruits of these species are 

 somewhat similar. 



E. eugenioides, Sieb., and E. capitellata, Sm., approach each 

 other very closely in morphological characters, and there often 

 seems to be a gradation between the two, but, nevertheless, the 

 two species are quite distinct; and so in this, although there also 

 appears some similarity in the fruits of this species and E. 

 eugenioides, yet the two differ in too many characters to be the 

 same species. 



The sucker-leaves are not unlike those of E. capitellata, whilst 

 the buds are similar to those of E. eugenioides. The fruits 

 approach somewhat in shape those of the latter species, with 

 which it has probably been confounded in the past when deter- 

 mined on dried specimens. 



If it were not for the distinctive character of the timber and 

 oil I should certainly have made it a variety of E. eugenioides, 

 but the former product is of too poor a character to be associated 

 with so excellent a timber as that yielded by White Stringybark, 

 E. eugenioides. The oil also differentiates it entirely from that 

 species. 



On the sum of the above differences it was decided to give the 

 tree specific rank, and botanically it is placed next to E. 

 dextropinea, Baker, from which it differs in the shape of the 

 fruits, bark, leaves and chemical constituents. From E. hevo- 

 pinea, Baker, it differs in the shape of the fruits, quality of 

 timber and constituents of the oil. 



Timber. — Of a dark brown colour (hence the specific name), 

 much affected with borers and not valued for durability by timber- 

 getters and others interested in the trade.
