4. With E. viminalis Labill. 



It resembles E. viminalis in its drooping foliage, flowers in threes, and smooth bark. 

 It has long been confused with E. viminalis, e.g., it is Howitts viminalis (6). See 

 " Eucalypts of Gippsland," p. 97, to which excellent account of the tree the student 

 should turn, its affinities to E. viminalis and E. Stuartiana being there clearly indicated. 

 It sharply differs from E. viminalis in its broad glaucous suckers. E. viminalis will 

 be dealt with in Part XXVIII. 



5. With E. cinerea F.v.M. 



Sometimes E. rubida flowers in the broad-leaved or juvenile stage, e.g., Kangiara, 

 via Bowning, figure 7a, Plate 110. In this case its resemblance to E. cinerea F.v.M. 

 (see figures lb and 5, Plate 89, Part XXI of the present work) is so great as to be striking. 

 But E. cinerea has a rough fibrous bark, while E. rubida is a gum; there are other 

 differences.
