sufficient room to display unconfmed their elegant growth. One of the finest 

 species for this purpose is Acacia dealbata, of which there is a splendid 

 specimen, now in the height of its beauty, in my own conservatory. I have 

 seldom seen a plant of any kiud equal in beauty to this, its wide-spreading 

 branches being completely covered with a garment of green and gold, or more 

 strictly speaking, with green and deep lemon colour ; the latter colour greatly 

 predominates, however, for the flowers are so numerous that they almost hide 

 the pretty bipinnatifid leaves. This tree roots into a border beneath the floor 

 of the house, and its stem was originally trained to one of the pillars that bear 

 up the roof ; but the stem is now larger than its former support, and the 

 branches extend in different directions to a distance of several yards. It has 

 been planted about eight years. A fine plant of Acacia vestita grows against 

 another of the pillars. This, from its profuse-flowering and pendulous habit, 

 is a very handsome species, and requires much less room than dealbata, which 

 precedes vestita in flowering by nearly a fortnight. To these might be added 

 other desirable kinds, as Acacia armata, a very free-flowering species, with 

 flowers like golden balls ; A. lophanta, with long spikes of whitish flowers ; 

 A. verticillata, with whorls of leaves like spines ; A. melanoxylon, the Black 

 Wattle of the Australians, with very curious leaves, the footstalks of which 

 look like leaves, with the real leaves hanging to the points of them ; and 

 A. pubescens, a very elegant species, with drooping branches and racemes of 

 ball-like flowers, borne in the greatest profusion. Indeed, all the species of 

 this genus are highly interesting, and most of them elegant ornaments for the 

 greenhouse or conservatory, deserving of general cultivation. 



ROSA CANNABIFOLIA. 



At a recent sitting of the Imperial Society of Horticulture at Paris, 

 M. Riviere, the intelligent gardener at the Luxembourg, made a statement with 

 regard to Rosa cannabifolia to the effect that it is only an accidental variety 

 of Rosa alba which has been fixed by grafting. The most prominent 

 character of the variety is, that the leaves are for the most part opposite, and 

 do not become alternate as in all Roses. In lately walking through the col- 

 lection of Roses at the Luxembourg, he there observed one plant of Rosa can- 

 nabifolia, on branches of which certain flowers had returned to the characters 

 of those of Rosa alba ; while others had preserved those which distinguish 

 R. cannabifolia, and these branches were submitted to the Meeting. This is, 

 then, another example of dimorphism which has been observed on different 

 plants. 



RAISING GRAPE VINES FROM LATERALS. 

 A few years ago Mr. Fleming, of Trentham, produced at a meeting of the 

 Horticultural Society some cuttings of Vines, which, in five days, had formed 

 roots as much as 3 inches long, and which had been prepared by a new pro- 

 cess. The usual methods of multiplying the Vine are by layers, or cuttings, or 

 eyes, each having so limited an application that much time must elapse before 

 any considerable number of plants of a new variety can be propagated. The 

 method pursued by Mr. Fleming is to take advantage of the laterals (which 

 every Vine may be forced to produce in abundance), to separate those laterals 

 close to the old wood as soon as . they have three or four leaves, and to strike 

 them in silver sand in the usual way.
