NATURAL GRAFTS BETWEEN INDIGENOUS TREES. 37 



a young White Gum had also grown. So that there were 

 two young trees, a Stringybark and a White Gum, the old 

 Stringybark serving as a 4fc pot." In process of time the 

 young trees became " pot-bound " and the two young trees 

 became squeezed together and finally fused." 



A few weeks afterwards Mr. O. T. Musson, of the 

 Hawkesbury College, Richmond, published in the College 

 Journal of the 18th January last, an account of a natural 

 graft to be seen on the farm. Out of a tree of Eucalyptus 

 tereticornis, Sm., 1 there is growing a smaller tree of 

 Angophora subvelutina. This natural graft is in rather a 

 bad way, and will apparently not live long. Mr. Musson 

 furnished the following very interesting report to the 

 Principal who has been kind enough to favour me with it : 

 " It appears to me that a seedling Angophora subvelutina 

 started in a hollow made by a branch of the Eucalyptus 

 breaking, and that the roots eventually reached the ground, 

 he eucalypt is splitting where the Angophora is thickest; 

 i.e., where it comes out of the surrounding gum trunk. 

 That part of the Angophora which is seen has expanded 

 somewhat close to the point of attachment where seen, 

 after the manner of a girdled tree. 



" With regard to the species of Eucalyptus it appears to 

 me to be the Cabbage Gum (E. tereticornis), but as there 

 are no fruits or buds, and as the leaves are mostly the 

 result of dormant buds developing and thus mostly are of 

 the sucker type, I am not sure." (I have confirmed the 

 determination, with the result stated in the foot note). 



It is not proposed to disturb the graft at present and 

 therefore it cannot be stated whether the woods of the 

 two trees are in absolute organic union as they are in the 

 specimen first described. It may be pointed out that Mr. 



1 It is a " Swamp Gum " and is provisionally referred to var. latifolia, 

 Benth. It is the E. amplifolia of Naudin.
