2. With E. odor at a, Behr. 



This has already been alluded to at p. 3G, Part XI of this work. The two 

 species are often a good deal alike — e.g., in the foliage, with the intramarginal vein 

 at some distance from the edge, the shape of the buds and of the fruits ; but the 

 two species are sharply separated by their anthers. 



HYBRIDISM. 



The Boxes seem to have a special tendency to hybridise with the Ironbarks. 



Mr. J. L. Boorman and I collected at Murrurundi, in May, 1902, specimens 

 which appear to be hybrids between E. sideroxylon and E. meUiodora. 



I have a different hybrid between the same species from the Inverell district 

 from Mr. Forest-Guard Gordon Burrow, both of which will be figured and described 

 when I deal with hybridism in this genus.
