E. Laseroni K. T. Baker. 

 A medium-sized tree, not quite a Stringybark, and hence known as Bastard 

 Stringybark. The fibrous bark covers the trunk and decorticates in long strips from 

 the main branches, which are otherwise smooth. 



E. Penrithensis Maiden. 

 A tree of medium size, bark hard-fibrous on the trunk, branches smooth, 

 intermediate in character between a Stringybark and a Peppermint. 



E. pilularis Sm. 

 This is the tree which most usually goes under the name of " Blackbutt,"' and 

 sometimes by way of distinction, for it attains enormous size, the " Great Blackbutt." 

 It is a stately, shapely tree, and perhaps the best known of all the genus to Sydney 

 residents, as it is so abundant. Its rough outer bark is confined to the trunk of the 

 tree, the branches being smooth and white. From the latter circumstance it shares 

 with some other species the designation of " White-top." The outer bark of this 

 tree is fibrous and closely matted, forming a sort of middle link between such fibrous- 

 barked trees as the Stringybarks, and such smooth ones as our White Gum. I do not 

 know that the term " black," as applied to the butt, is particularly appropriate; the 

 word " grey " would be better, though exception could be taken to this adjective ako. 



E. piperita Sm. 

 Not very dissimilar to E. pilularis in general appearance, but a smaller tree, 

 denizen of rockier conditions and with far inferior timber. Bark sub-fibrous on the 

 trunk, with smooth branches. Sometimes decidedly a ribbony Gum. 



E. radiata Sieb. 

 A tree usually moderate" sized, but sometimes attaining a considerable height 

 the bark fibrous and persistent, not so fibrous as that of a Stringybark, and of a looser 

 texture than that of a Box of the character usually known as Peppermint. The fibrous 

 bark occurs only on the trunk or at most on the largest branches. ' The branches are 

 usually quite smooth or ribbony. 



E. Sieberiana F.v.M. 



Looked at from some little distance most people would pronounce it an Ironbark, 



and, because of the clean white branches, it is sometimes known as White Ironbark. 



Sometimes the rough bark only reaches half way up the stem. The young branches 



and upper parts of the trunk are often glaucous — indeed, this seems always a character 



of the species. The bark is, however, by no means so hard as the Ironbarks, nor are 



the ridges so sharp or well sculptured; the bark is something between that of the 



Ironbarks and the Stringybarks; indeed it varies in texture between that of these 



two groups. 



E. taeniola Baker and Smith. 



A tree of 40-50 feet, with a Peppermint bark.
