NOTES AND ABSTRACTS.

a note by D. Perez, describing the few specimens extant — all the rest 

 having died out or been devoured by wild goats. These plants rarely 

 produce seeds, owing probably to senility of species, but a few have been 

 collected and raised at Lyons, whence conies this new and charming 

 sub-arborescent species. Height 3-4 feet, with graceful panicles of 

 blue flowers — almost perpetually in bloom. The best species are 

 S. arborescens Brouss, and S. fmticans Webb. S. brassicaefolia Webb, 

 imbricata Webb, macrophylla Brouss, macroptera Webb, and pulverula 

 Webb are of a dwarfer habit, with large sprays of flowers ; but all are 

 highly ornamental. M. J. Brun, of Montplaisir, Lyons, is the principal 

 cultivator. — F. A. T7. 



Stock on Scion, Influence Of. By G. Riviere and G. Bailhache 

 (Jour. Soc. Nat. Hort. Fr., p. 133, February 1908). — Another note on the 

 marked influence of the stock on the scion, taken this time from investi- 

 gations made on vines. — M. L. H. 



Stocks, Deep Planting" of Paradise. By the Duke of Bedford, K.G., 

 and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908, pp. 57-64). 

 Stocks planted 24 inches deep weighed three times as much at the end of 

 two years as similar stocks planted only 6 inches deep, new root systems in 

 the former case having been formed from the stems at the optimum depth 

 below the surface. Further investigations are being conducted. With 

 crab stocks deep planting gave bad results, as indeed it would do with all 

 worked trees. — A. P. 



Stocks, Fruit Tree. By C. T. Cole [Jour. Dep. Agr. Vict. August 

 1908). — Apples, in order to resist attack by woolly aphis (Schizoiveura 

 lanigera) are being grafted on ' Northern Spy ' and ' Winter Majetin,' both 

 stocks being immune to this pest ; the ' Northern Spy ' is the better stock. 

 There are other blight-proof kinds of apples which could doubtless be 

 used as stocks, but there is no need to increase the number except for 

 special purposes. To prevent the stock from becoming weaker in its 

 constitution from constantly working and re-working on the same variety, 

 Mr. Cole has worked ' Majetin ' on ' Spy ' and ' Maggs Seedling ' (another 

 blight-proof kind, and robust in constitution) upon the ' Spy,' with the 

 best results. For dwarf-apple culture the ' Spy ' can be used, and the 

 'French Paradise' worked upon the 'Spy,' and the desired kind again 

 worked upon the ' French Paradise.' There is now in this State, raised 

 from seed there, a ' Paradise ' apple tree of dwarfing habit, free surface 

 rooting properties, very easily propagated, and upon which the desired 

 kinds may be worked direct. All kinds appear to thrive admirably upon 

 it and it is quite blight-proof. Planters need to take care that their trees 

 are worked sufficiently above the surface of the ground to prevent the 

 scion from striking roots into the ground, and displacing the blight-proof 

 stock, thus rendering the whole tree roots liable to become a blighted 

 mass. 



Apricot. — The ' Mussel ' plum stock is found best ; ' La France,' a 

 variety of the Myrobalan, is largely used, as it is easily propagated from 

 cuttings and does not sucker.
