498 NOTES ON HYBRIDISATION IN THE GENUS EUCALYPTUS, 



E. AFFiNis Deane & Maiden, these Proceedings, 1900, p. 104, 

 with a plate. 



In that paper some doubt was expressed as to the hybrid 

 origin of E. affinis. I desire to say that I have now no doubt 

 as to its hybrid origin. Others and myself have found it grow- 

 ing over large areas of country with E. sideroxylon and E. hemi- 

 phloia var. alhens. The tree certainly is an intermediate between 

 this species and variety, and I look upon these trees as its 

 parents. 



E. SIDEROXYLON A. Cunn. X WooLLSiANA R, T. Baker, '* Mallee 



Box." 

 I have evidence that these two species frequently hybridise. 

 Mr. R. H. Cambage has drawn attention to these hybrids."*^ I 

 have emphasised the matter,! adding the Cooburn or Black Box 

 of the Narrabri district. 



E. SIDEROXYLON A. Cunn. X FASCicuLOSA F.v.M., " Mallee Box." 

 I believe these two species hybridise. 



E. PANICULATA Sm. X HEMIPHLOIA F.V.M. 



In these Proceedings (1901, p. 340) 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. 



E. POPULIFOLIA Hook. X FASCICULOSA F.V.M. 



I believe these two species hybridise. 



E. SALIGNA Sm. X ACAciiEFORMis Deane & Maiden (?). 



Mr. A. R. Crawford, Moona Plains, Walcha, sends me speci- 

 mens with the following note — " No. 5. Supposed hybrid 

 between E. maligna and E. acacice/ormis (Black Peppermint).
