E. propinqua Deane and Maiden. 

 A Grey Gum, very closely allied to E. punctata. 



E. punctata DC. 

 The typical Grey Gum. Bark dull grey in appearance, has a roughish or raspy 

 appearance, in contradistinction to a smooth and even shiny one, possessed by so many 

 of our Gums. It has smooth white patches in places, caused by the outer layer of 

 bark falling off. 



E. canaliculata Maiden. 

 A tall species, over 100 feet in height, with a diameter of 4 feet. Timber pale 

 coloured, somewhat coarse-fibred, interlocked and tough. 



E. MACULATA Hook. 



A tall, smooth-barked tree, more or less blotched, giving it a spotted or 

 mottled appearance, hence the name " Spotted Gum," which was originally applied 

 to this species. Timber pale coloured. 



2. HEMIPHLOISE (Half-barks). 



The illustrative instances Mueller quotes in his 1859 paper are Moreton Bay Ash 

 (E. tessellaris) , the Blackbutted Gum (a term now archaic and shortened to Blackbutt, 

 of which E. pilularis is the type, and Box-trees partim, amongst which he probably 

 intended to include E. hemiphloia, the tree which was first named Box, but he badly 

 mixed it up when he described it later. See this work, Part XI, p. 14. It 

 includes most of the Peppermints. 



The outstanding fact is that the average bushman unhesitatingly does not greet 

 the Hemiphloise as Gums, but realises that the rough, sub-fibrous bark proceeds a 

 considerable distance up the butt, often to the first fork. As a rule, the upper part of 

 the butt, and always the limbs, are smooth. The Hemiphloise are intermediate between 

 the Leiophloise and the Rhytiphloise. There are no abrupt stages in Nature, and so it 

 is that sometimes an exceptional member of the Leiophloise may have so much rough 

 bark that it verges towards the Hemiphloise, while a member of the Hemiphloise tends 

 to the rough-barkedness of the Rhytiphloise. Nevertheless, the Hemiphloise afford 

 us a useful practical classification. 



It is remarkable that the vast preponderance of the Hemiphloise have pale 

 timbers. 



My provisional grouping is — 



A. — Renantherce. — -Eastern species. Timbers pale. Different members are 

 known, chiefly as Peppermint, but also as Blackbutt and Mountain Ash. The bareness 

 of the branches is sometimes emphasised in the name White Top.
