FURTHER NOTES ON SUPPOSED HYBRIDISATION 

 AMONGST EUCALYPTS (INCLUDING A DESCRIP- 

 TION OF A NEW SPECIES). 



By H. Deane, M.A., F.L.S., &c., and J. H. Maiden, F.L.S., &c. 



The question of hybridisation amongst Eucalypts has been a 

 moot one for many years. Recently we called attention to the 

 subject (these Proceedings, 1900, xxv.. Ill), and Mr. R. H. 

 Cambage has a further note {ibid., xxv., 716). We would point 

 out that in supposed cases of hybridism an Ironbark has hitherto 

 been generally looked upon as one of the parents. 



We again invite attention to the trees distinguished in a former 

 paper as 5, c, d, e,y* (these Proceedings, 1900, xxv., pp. 111-112). 



We amend our reference to h by stating that an extended 

 series of specimens shows that its anthers do not really differ 

 from those of c, c?, e and/. We look upon all these trees, viz., 

 6, c, d, e, /, as belonging to one species, all the differences noted 

 being referable to local variation. 



It has already been shown that this tree possesses affinities 

 both to E. siderophloia and hemiphloia; some botanists may look 

 upon it as a variety of either species. To our mind it occupies a 

 position so intermediate between these two species that we have 

 from time to time provisionally called it E. siderophloia, var. 

 hemiphloia, and E. hemiphloia, var. siderophloia; but both these 

 descriptive names have the objection, in our view, of committing 

 one to a definite opinion as to the parentage of the species. As 

 it seems sufficiently constant in its characters over a large area, 

 we think the wisest course is to give it a definite name, and 

 therefore propose to call it E. Boormani, after John Luke Boorman, 

 a collector of the Botanic Gardens, who, in regard to this and
