hemispheric form." In regard to these statements, I would observe that E. 

 hcemastoma is a smooth-barked tree, and that those rough-barked trees which were 

 tliought to show some transition towards E. Sieberiana (as well as to other species) 

 have since been shown to belong to other species. 



The Sydney or depauperate form is often confused with E. hcBmasloma, as 

 the young trees often have the appearance of White Gum if the butts be not carefully 

 examined, and they are often so small that it is not easy to detect the rough bark. 



If E. Sieberiana leaves be crushed in the warm hand, they evolve a slight 

 odour of peppermint which is not observable in E. hcemastoma. 



In the "Flora Australiensis," Bentham also draws attention to the affinity 

 between E. Sieberiana and E. hcemastoma, and lays some stress on the differences 

 between their anthers. I am of opinion that it is impossible to distinguish the two 

 species by means of their anthers. 



5. With E. coriaeen, A. Cunn. 



Both Bentham and Mueller compare E. Sieberiana and E. coriacea. The 

 closest similarity appears to be in the shape of the fruits. For fruits of E. coriacea, 

 see Plates 26 and 27, Part V of this work. They are coarser and more fleshy than 

 those of E. Sieberiana ; the coarse, fleshy, spreading veins of E. coriacea are also 

 characteristic and quite different from those of E. Sieberiana. In addition, E. 

 coriacea is a smooth-barked tree, while E. Sieberiana is rough-barked. 



6. With E. obliqua, L'Herit., var. alpina, Maiden (E. delegatensis, R. T. Baker). 

 This is that " Mountain Ash " which, in the high Southern Ranges of New 



South Wales, and also in Victoria, " succeeds " E. Sieberiana at a higher elevation 

 than the latter attains. It is the E. Sieberiana (b) of A. W. Howitt* ; see also 

 p. 69, Part II, and p. 177, Part VI, of this work. I desire to pay a further visit to 

 this tree in the field, after which I will again refer to it and contrast it with 

 E. Sieberiana. 



7. AVith E. vitrea, R. T. Baker. 



Mueller, " Eucalyptographia " (under E. Sieberiana) says : — 



. . . occurring also on low moist sandj' tracts between the Glenelg River and Mount 



Gambler and Lake Bonney (Dr. Wehl) 



. . . . in the cripply Stringybark forests near Lake Bonney (this is in South Australia ; a long 

 narrow body of water running parallel with the coast-line, north from Cape Banks, and not very far from 

 the Victorian border. — J.H.M.), dwarfed to 10 or 12 feet, though amply flowering. 



I am of opinion that these specimens come nearest to or are referable to 

 E. vitrea, R. T. Baker ; see pp. 164-7, Part VI, and p. 189, Part VII, of this work. 



Since the above was written I have received specimens from Penola Forest, 

 S.A. (not far from the Victorian border), from Mr. Walter Gill, with the following 

 notes : — 



. . . . what everything indicates to be A'. 5te6e?-irtwa. It is a stunted form and weeping habit, 

 and grows in low-lying country under water in winter.
