E. vemicosa Hook. f. (S.) 



E. viminalis Labill. Beyond the Blue Mountains, New South Wales, e.g., Cox's 

 River to Fish Eiver, Mount Blaxland to Rydal, Sidmouth Valley (all R. H. Cambage 

 and J.M.H.), we have collected this species with fruits and juvenile leaves on the same 

 twig. 



Mr. A. D. Hardy figures an example of precocious fruiting amongst resting buds 

 in E. exigenioides in Gippsland. He says he has also seen it in E. obliqua. I have seen 

 it in E. eugenioides in the Sydney district. {Proc. Roy. Soc. Vict, xxix (New Ser.), 172, 

 and Plate 13, 2.) 



Eucalyptus alpina was grown in the Centennial Park, Sydney, from seeds obtained 

 from the Victorian Grampians, and it is one of the surprises of acclimatisation that it 

 succeeded there admirably. Mr. A. A. Hamilton, in whose care the tree was, informs 

 me as follows : — 



The first buds whicli appeared developed slowly, and at the end of one year were still diminutive. 

 In the second-flowering season a further set of buds appeared, which behaved in a similar manner to those 

 of the first year, the latter increasing in size, but still remaining unopened. This again occurred in the 

 third year, three separate sets of buds in different stages of development appearing on the plant at the 

 same time. At the close of the third season the first year's buds flowered, and finally fruited nearly four 

 years after the buds first appeared fln the plant. At this period there were four distinct phenological stages 

 of floral growth present. 



G.— Dominance or Aggressiveness of Certain Species. 



This is a subject which has scarcely occupied the attention of Australian foresters 

 yet, or at all events they have rarely written about it. 



Some years ago I pointed out to Mr. GoUan, the Superintendent of the Gosford 

 Nursery, New South Wales, a flourishing tree of E. numerosa Maiden, in a border adjacent 

 to the boundary fence. A slender species, it seemed to be flourishing as well as any 

 species in the border. I several times during various years visited this tree, because 

 of the personal interest I took in the sjDecies. 



In 1915 I was present at the dedication of the Strickland Forest, a few miles 

 away, and pointed out to some people the way in which this species (a southern one) 

 was taking possession of a fairly large area of the forest, its spread being far greater 

 than when I had visited the forest a few years previously. I pointed out that this was 

 the first Eucalypt I had known to behave in such an aggressive manner. 



I was therefore much interested to read that Dr. L. Cockayne, F.R.S., in his 

 " New Zealand Plants and their Story," gives an example of the aggressive character 

 of a species of Eucalyptus. 



At Waitati, near Dunedin, on the land belonging to the Mental Hospital, stands a fine example of a 

 kind of iStringybark (PJumhjplus numerosa), more than fifty-eight years of age. Originally the vegetation 

 of the area was mixed Taxad forest, but this has been replaced by a close growth of Manuka thicket 

 (consisting of various low shrubs). Some years ago this thicket was burned in the neighbourhood of the 

 tree, and a young forest of gums'several acres in extent has sprung up, the n^w ground and the potash 

 from the fire being eminently suitable for the germination of the Gum-tree seeds. In 1910 the Gum sai^lings
