ABSTRACT OF PKOCKKMNGS XXI. 



Adhesion or true grafting in Eucalyptus is very much rarer, 

 and the only authentic case in literature known to me is recorded 

 of two unsatisfactorily named species by M. Felix Sahut in France 

 in 1864. He used two methods, the cleft graft, with moderate 

 results only, and the graft by approach, or inarching, with much 

 greater success. 



The ''Revue Horticole," published in 1893 an account of the 

 budding of E. globulus on E. resinifera carried out by M. Justin 

 Dugourd in Palestine. The "Gardeners' Chronicle" for 11th 

 March, 1899, p. 145, may be turned to for a fuller account of both 

 these experiments, and it is remarkable to what extent classical 

 experiments on Eucalyptus from the horticultural aspect have 

 been made by Frenchmen. 



(ii.) Here I may invite attention to my paper in this Journal 

 (xxxvin, p. 36) "On some natural grafts between indigenous trees, ' ; 

 reprinted, with some additions, in my "Forest Flora of N.S.W.," 

 vi, 79. The graft between the White Gum and the Stringybark 

 is a perfect one, and the specimen is still available for examination 

 at the Botanic Gardens, but the evidence in regard to most reports 

 of grafts in which Eucalyptus is concerned breaks down on investi- 

 gation. 



Grafting by approach in Eucalyptus is easy when the plants 

 are little past the cotyledon stage, according to some experiments 

 by Mr. C. J. Weston of Canberra. In practice they sometimes 

 result in pans of mixed seed, two diverse seedlings being accident- 

 ally pressed together in the operation of potting up. 



In the nursery rows at Canberra are three sturdy plants of E. 

 rubula-maculosa. When I saw them in July, they were about 

 three fe;et high and spreading. One half of each plant has the 

 typical maculosa character. Stripping the soil from the root shows 

 perfect fusion of the two trees. This grafting by approach or 

 fusing of two species by pressure applied at a critical time could 

 hardly be avoided, in the bush, by the agency of animals treading 

 amongst young seedlings.
