Summary. 



E. viminalis, Labill. 

 Three-Jlowered : — 



a. With large fruits : var. Baeuerleni [E. Baeuerltni, F.v.M.) 

 Multi-fiowered : —

pedicellaris, F.v.M {E. Smithii, Baker), 

 c. Form with linear leaves for which we propose no variety 

 name. 



E. GUNNII AND E. VIMINALIS. 



With all the varying forms of these two species, they fall 

 naturally into two series, those with broad suckers {E. Giiniiii) 

 and those with narrow suckers {E. viminalis). It is quite true 

 that the width of the suckers varies in some forms, but never to 

 such an extent as to render it really doubtful to what species a 

 given form belongs. 



E. vimi7ia'is, E. Gunyiii and its varieties may all have ribbony, 

 scaly, and even hard black bark (in exceptional cases) up to first 

 fork and beyond. In the present state of our knowledge we are 

 unable to discriminate between the various kinds of timbers 

 belonging to the two species. 



The affinity of E. viminalis, Labill., is undoubtedly very close 

 with E. Gunnii, Hook. f. We go so far as to say that in the 

 present state of our knowledge, unless fruits or suckers be 

 available, it is not always possible to say whether a certain tree 

 is E viminalis or E. Gunnii. This more particularly applies to 

 certain trees in Western and Northern New South Wales, at 

 great distances from the home of the typical forms. 



But while indicating that in our opinion there is no absolute 

 line of demarcation between E. viminalis and E. Gunnii, we 

 would observe that it can be said of many other species of 

 Eucalyptus that they are closely related to congeners. E. vimi- 

 nalis and E. Gantiii both include large numbers of trees with 

 smooth bark; the fruits of the former are often in more than 

 threes; those of E. Gunnii are usually more than three. The
