AFFINITIES. 



1. With E. oligantha Scliaiier. 



Its closest affinity appears to be with this species, but E. oligantlia has paler 

 foliage,, iirceolate cal3^x-tube, which does not continuously taper into the pedicel, 

 much shorter filaments, and capitate stigmas. The anthers of the two species are 

 similar, but not identical. E. oligantha is described as shrubby (but later it may prove 

 to attain tree size), but we know nothing of its bark and timber. The fruits of neither 

 species are knomi. 



2. With E. Spcnceriana Maiden. 



As a rule this sj)ecies has thin, graceful, lanceolate leaves, but occasionally it 

 lias coarser foliage, e.g., the Stapleton, Northern Territory, plant shown at fig. 4, 

 Plate 156, C.R. But even in that tree, which presents a good deal of similarity to a 

 tree of E. Hillii, the foliage is not broad as a whole. Also, the bark of E. Spenceriana 

 is not tessellated ; it is a Box. The fruit of E. Spencer imia is small and of papery or 

 angophoroid texture, which that of E. Hillii can never be. 



3. With E. alba lieiuw. 



A large leaved, long petiolate species suggesting a similarity to E. alba. For 

 that species Plates 105-7, C.Pt., may be referred to. But £". alha differs in buds and 

 anthers, and in developing into lanceolate leaved forms.
