106 ON THE EUCALYPTS OP N.S.W., PART VII., 



Mr. Cambage is of opinion that the tree is a hybrid between 

 E. hemiphloia, v. albens, and E. sideroxylon, a view which had 

 already occurred to us. It certainly seems only to be found 

 when the other two trees are present. There are difficulties in 

 the way of recognising hybridism in Eucalypts, and as we pro- 

 pose to treat this subject later on we refrain from being dogmatic 

 on the present occasion. 



Below we give an account of some trees which partake of the 

 characters of both an Ironbark, probably in this case E. sider- 

 phloia, and a Box, E. hemijMoia, and here hybridism again suggests 

 itself. It is curious that in E. affinis we have a tree also partaking 

 of the characters of an Ironbark and a Box, but in this case E. 

 sideroxylon and E. hemiphloia, var. albens, apparently combine. 



In view of the imperfect evidence of hybridisation before us 

 we think it safer to give to E. affinis specific rank. 



Eucalyptus Cambagei, sp.nov. 

 (Plates vi.-vii.) 



A small or medium-sized tree. 



Vernacular names. — " Bundy" of Burraga, Rockley and some 

 other places; called also " Bastard Apple, " Bastard Box," and 

 " Grey Box" in different localities throughout the Bathurst and 

 Orange districts. The glaucous form is " Rough-barked Mountain 

 Apple." See Part v. of this Series (Proceedings, 1899, p. 163}, 

 under E. goniocalyx. 



Bark — A fibrous matted bark of a dirty grey colour, inter- 

 mediate in character between that of E. St.uartiana and that of 

 E. hemiphloia; the rough bark extending to the tips of the 

 branches. 



Timber. — Wood pale-coloured, apparently tough, but very little 

 definite information concerning it is available. It is hard and is 

 used extensively for fuel for copper furnaces at Burraga accord- 

 ing to Mr. Cambage. 



Sucker leaves. — Strictly opposite, later becoming alternate, very 

 broad (up to 5 inches broad and 5 inches long), nearly orbicular
