of those of E. melliodom, and while seized of its affinities to E. paniculata, E. siderophloia and E. hemiphloia, 

 there was certainly evidence to look upon it as an aberrant form of E. melliodom and also of Bosistoana, an 

 affinity which (as regards the latter species) had already been arrived at by Mueller (though in a different 

 way) as regards the Cabramatta specimens. The fruits are a shade smaller than those of some specimens 

 in our possession, and we have from time to time looked upon the tree as a possible hybrid between 

 E. paniculata and E. hemiphloia, and E. paniculata and E. melliodom respectively. We have examined the 

 trees referred to by Dr. Woolls and Mr. Cambage, and are of opinion that, while they may be properly 

 described as " Black Box " and " Ironbark Box," there are certain points of difference between them and 

 the Cabramatta trees (E. Boormani) which make us hesitate in referring them to the same species. The 

 foliage and fruits are less coarse than those of Cabramatta, and this circumstance, coupled with the fact 

 that the trees grow amongst E. paniculata, may cause some observers who may be inclined to look upon 

 the Concord trees as hybrids to consider that E. paniculata is one of the parents. Bearing in mind that 

 cases of hybridisation amongst Eucalypts usually break down under fuller examination, we. hesitate to 

 believe that we have a case of hybridisation here, and will revert to the subject at some future time. 



Four years later I stated that I had no doubt as to its hybrid nature. I had had 

 the tree under observation in the meantime, and was of opinion that it was a form 

 sufficiently distinct to receive a name. 



E. paniculata Sm. x hemiphloia F.v.M. In these Proceedings (1901, p. 310) Mr. Deane and I 

 referred, though with some doubt, to a " Black Box " or " Ironbark Box " from Concord, near Sydney. 

 I desire to say that, having kept these trees under observation, I have no doubt as to their being hybrids of 

 the species named. (Proc. Linn. Soc. N.S.W., xxx, 498, 1905.) 



Eight years later still, I described the tree under the name E. hybrida.
