See also a natural graft between E. obliqua and E. vimutalis at Turritaljle Creek, 

 Macedun, Victoria, reported l)y A. D. Hardy. {Proc. No/j. Soc. Vlcf., xxix. (New Series), 

 100.) 



Mr. A. D. Hardy also gives a case of lieterotropy (rever.sed direction of growth 

 of branch), in the form of a drawing of a branch of a reputed liybrid of E. lieiiufhloia 

 X meUiodom, between Stawell and the Grampians. Victoria. (Plate 12, Proc. Roij. 

 Soc. Vict., xxix (New Series), p. 109.) 



There was also reported to me as a natural graft E. maculala (Spotted Gum) 

 (this was green) and E. paniculata (Grey Ironbark) (this was dead). The trees were at 

 Gessnock, New South Wales, and the observer, Mr. F'. G. McPherson, District Forester, 

 Wyong, New South Wales. I have a photograph. Init in view of the death of the 

 Ironbark the graft does not appear to have been perfect, and it is probably one of the 

 so-called false grafts, i.e., where one tree grows in another, the latter being a sort of 

 container or flower-pot. 



The late Dr. G. V. Perez, of Teneriffe, who died in January, 1920, was a man 

 whose work was admired by horticulturists throughout the world. He took the liveliest 

 interest in Australian plants. "Amongst othefs he cultivated E.ficifolia and E. calophyUa. 

 Following are extracts from sonie of his latest letters, and which refer to adhesion of 

 branches (grafting by approximation, approach, inarching, are more or less synonymous 

 terms, though in strictness, inarching only takes place when scion and stock are growing 

 on their own roots). 



In order to preserve a very beautiful Eucalyptus liybrid, which I am growing from seeds sent from 

 Sydney as E.ficifolia (cherry-coloured) (this is E. calophi/lla var. rosea. — J.H.M.), I am grafting bv approxi- 

 mation, placing the stock in a large and long bamboo ; the method succeeds very well, and I should say 

 that to preserve any pretty shade of colour it will be valuable. I am going to employ as stock the hybrid 

 calophyUa xfici/olia. as E.fici/olia is much more delicate in the bad soil I have here, and besides the " Chcrrv '' 

 I wish to preserve is a hybrid, which does not breed true from seeds; I have thought that what I have 

 written may possibly be of some interest. (Slst March, 1919.) 



I shall now endeavour to obtain several plants of one which you sent as E.ficUolia, and which is 

 certainly a hybrid, often referred to in my correspondence with you as " Cherry " colour {cahpliylla 

 var. ro-^ea. — -J.H.M.), and most beautiful and floriferous, which began to flower when only four years old, and 

 the progeny of which began to flower as early as two years old, some of them being white, some resembling 

 the jiarent plant, and .some rosy-pink (on Mendelian lines probably. — J.H.M.). The colour is so beautiful 

 that it is worth while preserving by grafting by approximation, by the method above named, and grafting 

 on its own stock; I have already two successfully grafted and ])lanted out, but on (?) trno fie ij alia, which is 

 not such a good stock. 



. . . . with reference to what I wrote about grafting E. ficijoUa by ajjproximation in large 

 and long true bamboo tubes, allow me to add that a small tree grafted in this manner, and which is only 

 about half a yard high, and which has only been in the ground about one year, is about to flower ; its parent, 

 the seeds of which were sent by you, is of a beautiful fire or o.range colour, and I presume it is the true 

 fi'ifoHa, which, according to you, is often of this colour. (I8th Juno. 1919). 



In my last letter I alluded to a tiny Eucalyptus whicli I had grafted by approximation; it has 

 flowered. It is of the fire or orange kind. If there is any novelty about this kind of grafting of coloured 

 Eucalyptus to preserve the pretty kinds, perhaps you would like to know that it has been a most successful 

 way of grafting in my hands: I first grow the stock in a long and large true hanilwotube, and attarli it 

 to the tree I wisli to graft on and propagate. (5th July, 1919.)
