as an Ironbark-Box hybrid, its parents being E. sideroxylon and 

 E. hemiphJoia, var. albens. 



The species has undoubted affinities with E. Bosistoana. The 

 late Baron von Mueller recognised this by confusing the two 

 species; or, to put it in another way, by including the Ironbark 

 Box with Bosistoana (see the original description, and our note, 

 these Proceedings, xxv., 112). They can, however, be readily 

 distinguished by the rough branches of E. Boormani, while those 

 of E. Bosistoana are smooth, like the Boxes (E. hemiph/oia, &c.). 

 At the same time it must be noted that the rough bark on the 

 butt of E. Bosistoana often displays considerable similarity to 

 that of E. Boormani.
