Weeping Gum = Euc. paucifloia, Sieb. 



Blue Gum = Euc. globulus. Lab. 



White Gum = Euc. viminalis, Lab. 



Caudlebark = Euc. rubida, Deane and Maiden. 



Cider Gum = Euc. gunnii, Hook. 



Perrins Gum = Euc. perriniana, F.v.M. 



Mueller's Gum = Euc. muelleri, T. B. Moore. 



Dwarf Gum = Euc. vernicosa, Hook. 



Urn Gum = Euc. urnigera, Hook. 



Heart>leaved Gum = Euc. cordata, Lab. 



Ovate Gum = Euc. ovata, Lab. 



Apple-scented Gum = Euc. stuartiana. 



All these fall into two natural sections, which for 

 brevity we will call Sections A and B. irees belonging 

 to these are vei-y distinct to the expert, but it is not 

 always apparent to the student. There is one clear dis- 

 tinction getween the two sections which, though small, 

 indicates a radical divei-gence, and that is in the shape 

 of the anthers. In A tlie two halves of the anthers 

 diverge so as to cause it to assume the shape of a kidney. 

 In B the two halves are straight and parallel. 



The first eleven in the list belong to A. Besides the 

 shape of the anthers there is a general resemblance. The 

 flowers, except in one form of Mouiitaiu Ptjtprrniinf, are 

 numerous in the umbel. The veins of the leaf are few, 

 and tend more to a longitudinal than a divergent course. 



To B belong the rest. Except in Orate and Apple- 

 Jicented Gum, the flowers are in three or one, only abnor- 

 maJly in more. The veins are numerous, diverging, and 

 netted. 



In Section A there are two sul>sections, the Prpjier- 

 mints and the Messmates, or Striugies. The Peppermints 

 mostly have narrow, equal-sided leaves, and the capsules 

 are nob at all constricted at the mouth. The Strinyies 

 have leaves with one half larger than the other, and the 

 capsule constricted at the mouth. Mmnitaiii Ash and 

 Weeping Gum may be recognised from the other Stringies 

 by the verj' longitudinal veins. 



Section B is not capable of being split up into natural 

 groups. Blue Gum, and sometimes Dwarf Gum, bears 

 single flowers. Ovate and Apple-scented have more than 

 three floAvers in the umbel. White and Vandleharl- have 

 very protruding valves to the fruit, and usually oblique 

 leaves. All the rest, together with Dwarf Ginn, are a 

 group closely related to Cider Gum.
