E. leucoxylon is not fibrous (" bos "-like) but smooth or ribbony. The fruits of 

 E. leucoxylon have usually a deciduous rim encircliug the orifice, are more hemi- 

 spherical, often warty, and often attain a very much larger size. 



3. E. siderophloia, Benth. 



The foliage of this species is not, as a rule, glaucous, bvit where it occurs in 

 the western districts it is often so, and forms the variety glauca. The juvenile leaves 

 of E. sider'ophloia are very coarse, the mature leaves are much the same as those of 

 E hemiphloia, var. albens ; the buds of E. siderophloia are " egg-in-egg-cup," and 

 with a longer operculum ; the fruits of E. siderophloia are smaller and of a different 

 shape, and with exserted valves. As to the trees themselves, E. siderophloia is an 

 Ironbark with red timber, while E. he^niphloia, var. albens is a Box with pale brown 

 timber. 



4. E. polyanthemos, Schauer. 



Howitt has already drawn attention to the similarity, " when the leaves (of 

 E. polyanthemos) are not markedly elongated." 



Its characteristics accord entirely with the diagnosis given in the " Eucalyptographia," with the 

 exception that the umbels are formed by buds of comparatively large size. The fruit is proportionately 

 large. The bark also extends frequently far up the branches, so that when the leaves are not markedly 

 elongated, this tree I'esembles, as I have already said, at first sight, the mountain form of E. polyanthema. 

 Yet, so far as I have observed, the two species are sharply marked off from each other. — (Howitt, the 

 abstracted paragraph referred to at p. 23). 



The timber of E. polyanthemos is red, the fruits are smaller and of a different 

 shape. I think the chief resemblance of the two trees lies in their glaucousness.
