AFFINITIES. 



1. With E.faseieulosa, F.v.M. 



See " Eucalyptographia," where the description of E '. paniculata is mixed up 

 with that of E. fasciculosa (deemed by Bentham and Mueller to be a variety of it). 

 I will go into the matter when E.faseieulosa is reached. 



2. With E. erebra, F.v.M. 



This is a drooping, narrow-leaved species, with vei*y red timber. It is usually 

 smaller in all its parts than E. paniculata while the anthers of the latter are 

 terminal-opening, very different to those of E. erebra. The var. angustifolia of E. 

 paniculata is closest to E. erebra. 



3. With E. siderophloia, Benth. Another Ironbark. 



See part X of this work, part 39 of my "Foi'est Flora," also " Eucalpyto- 

 graphia " under E. paniculata. 



4. With E. sideroxylon, A. Cunn. A " Mugga " or " Bed Ironbark," see Part 



12 of this work, and Part 13 of my " Forest Flora." 



Usually they are different enough, but I have seen very coarse-fruited 

 paniculata with a rim to the fruit, showing some ti*ansit to E. sideroxylon. 



5. "With E. melliodora, A. Cunn. 



Mueller has given a caution. See " Eucalyptographia " under E. paniculata. 

 See also Part 9 of my " Forest Flora." 



In distinguishing an Ironbark from a non-Ironbark, it is convenient in 

 practice to test a twig to the breaking point with the fingers. With a little 

 experience one can generally select an Ironbark in this way, because of its high 

 tensile strength. 



6. With E. bicolor, A. Cunn. (E. largiflorens, F.v.M.). 



See " Eucalyptographia " under E. paniculata. This is another species with 

 sub-cylindrical fruits. E. bicolor is a spreading tree of the interior; E. paniculata 

 is confined to the coastal strip, and is more erect in habit. E. bicolor has a black, 

 flaky box-like bark, while E. paniculata is an ironbark. The latter has a pale 

 timber, while that of E. bicolor is deep red. 



7. With E. ealycogona, Turcz. var. gracilis, Maiden. (E. gracilis, F.v.M.). 



I mention this because Mueller in rf Eucalyptographia " under E. paniculata 

 has mentioned it, and it is probably Bentham's var. (?) conferta of paniculata, hut 

 in practice I see no danger of their being confused.
