E. Caleyi Maiden. 

 A tall tree, often glaucous, and finally becoming glabrous, but remaining dull- 

 coloured. Called " Broad-leaved Ironbark " in comparison with narrower-leaved 

 Ironbarks (E. sideroxylon and E. crebra) and sometimes " Drooping Ironbark," a 

 character it possesses in common with E. crebra. 



E. CREBRA F.V.M. 



A tall tree, with drooping branches. Very deeply furrowed, in depth only (if 

 at all) inferior in that respect to E. sideroxylon. Timber red. 



E. Culleni Cambage. 

 Bark hard, rough, furrowed. A Queensland species. Timber red. 



E. decorticans Bailey. 

 " Naked-top Ironbark " or " Gum Top." This is remarkable because of its 

 deciduous branches. Bark on the butt with flat ash ridges reminiscent of 

 E. siderophloia. 



E. DREPANOPHYLLA F.V.M. 



A typical Ironbark, long confused with a Box (E. leptophleba). 



E. MELANOPHLOIA F.V.M. 



An Ironbark, inferior for economic purposes, which often goes under the 

 name of Silver-leaved. 



E. PANICULATA Sill. 



An erect tree, Pale or Grey Ironbark, the king of all Ironbarks, because it 

 possesses all the best characteristics of typical Ironbark timber, viz., strength, 

 durability, weight. Bark often pale-coloured, even grey. Furrows often anastomosing. 



E. siderophloia Benth. 

 The ridges the flattest of those of any Ironbark. Examination of the photo 

 of the trunk from Wyong, New South Wales, in Part XXXIX of my " Forest Flora 

 of New South Wales," shows that the bark of this species may be not furrowed, but 

 flaky. Usually, however, it is an indubitable Ironbark. 



E. sideroxylon A. Cunn. 

 A small, medium-sized, or even tall tree, often gnarled. Dark, the deepest 

 furrowed of the Ironbarks. It often occurs on the Goldfields of New South Wales 

 and Victoria. "Mugga." 



E. ST ALGERIAN A F.V.M. 



A medium-sized tree, with glaucous, lemon-scented foliage, from which a 

 perfume oil is distilled. It is, however, rather a scarce species. 



Let us now consider the Ironbarh-Boxes. 



These are intermediate species connecting the Ironbarks with the Boxes. 



The present seems a natural place to put them in. They have something of 

 the Ironbark character and the Ironbarks readily cross with the Boxes. The subject 

 will be further pursued under Hybridisation in Part LIII, where, amongst other 

 crosses, are some striking ones between these two groups of Eucalypts.
