Hybridism. 



I have specimens from .Jilliby Jilliby, near Wyong (J. L. Boorman), which 

 are intermediate in character between this species and E. saligna Sin., and may 

 indicate hybridism. 



AFFINITIES. 



With E. saligna Sm. 



Its closest affinity appears to be with this species ; indeed, it was for some 

 years looked upon as a variety of it, but its generally larger size, its broader 

 juvenile foliage, its dense massy crowns, which remind one of a laurel, more 

 spreading in habit than E. saligna, its smaller buds and fruits, slightly different in 

 shape, sufficiently characterise it.
