Appendix. On some Natural Grafts between Indigenous Trees. 
A supposed Natural Graft at the Hawkesbury Agricultural College Farm, 
Richmond, N.S.W. 
This was provisionally described at page 79, Part liv, of the present work, and 
Mr. C. T. Musson, Lecturer in Botany at the College, reports now on the subject : 
As the tree has been cut down, and the Swamp Gum host has broken open, we have facts now to 
settle the matter. 
"The Apple was a seedling that started in a hollow branch, the roots grew down through the 
accumulated soil in the gum, which proves to have been a mere shell. . We can see no sign of union ; 
only an enlargement above where pressure of the Gum was exerted on the under (or, outer, lower) side 
of the Apple, just where it emerged from the hollow in the host tree; this enlargement eventually becoming 
prominent for at least two-fifths of the circumference of the Apple. 
The accompanying photographs (not reproduced) show : 
1. The Apple roots still attached to their stem which lies in the hollow broken gum. 
2. The gum stump with lower end of the roots still remaining in situ. 
Therefore, it is not a case of grafting at all." 
I would invite the attention of readers to a short article on natural grafts, with 
some very good illustrations, in the Missouri Botanical Garden Bulletin, iv, p. 38 (1916).

It is, however, not a graft at all, the hollow stem of the White Box acting as a flower pot. Attunga, near

CALEY'S IRONBARK. 
(Family MYRTACE^:.) 
Range. See also vol. vi, p. 87. Mr. Gordon Burrow, Acting District Forester 
at Narrabri, reports : 
E. Caleyi is plentiful in the Counties of Hardinge and Arrawatta, though in the latter county, north 
of Ashford, the largely predominating ironbarks are E. crebra and E. melanophloia. In the County of 
Gough, I do not know of it east of the Waterloo Range and Emmaville. It extends only a very little over 
the border of the Counties of Burnett, Murchison and Darling. I have also collected it (identified by you) 
in the Parish of Dungowan, County of Parry, though it is very scarce there, and was told that scattered 
trees or belts were to be found on the opposite side of the Peel River, on the Goonoo Goonoo Estate. I 
have also been told that there is a little of it growing near Scone, but cannot vouch for this. It seems to 
me interesting only as forming a link between the Inverell District and other localities as given in ycur 
Forest Flora, i.e., Denman and Rylstone. 
Although it is plentiful around Inverell and Howell, it becomes scarcer as one travels north. I 
found it on the Ashford- Emmaville Road within a mile of three other ironba rks, viz., E. crebra, E. sideroxylon 
and E. melanophloia. I cannot hear of it across the Queensland border at aJI. Its range east and west seems 
very limited ; it does not appear to cross the Waterloo Range, nor to grow far (if at all) west of Delungra.
