This exhibition, which opened on the 18th May and extended over a week, was held in the Palais de l'lndustrie, and as the French system of showing is so very different to what is seen in this country, perhaps a few remarks on the above may be interesting to the readers of the ' Gardener' who have not had an opportunity of witnessing a Parisian flower-show. Wherever an exhibition is to be held, either in or about Paris, the ground is carefully measured and laid off in the style of a flower-garden, with broad walks intersecting, the figures being allotted to the different exhibitors according to the space they may require. In the flower department the centre of the figure is generally filled with fine foliage-plants, edged with dwarf Azaleas, Geraniums, Coleuses, &c; the pots plunged entirely out of sight often leads the uninitiated to believe that the plants are permanently bedded out. Fruit-trees, again, are shown in different modes of training - horizontal, fan, and pyramidal; this in itself is very useful, and seems to attract considerable attention. The gold medal for a collection of Azaleas was awarded to M. Margottin for a most effective contribution of about"thirty varieties, all standards, the stems varying from 1 1/2 to 2 feet high, bearing flat-trained heads.

Although this mode of training is not exactly in keeping with our English ideas of what an exhibition Azalea should be, still when placed in rows or massed together, and all of a uniform height, the effect produced is very striking.

M. Bleu put up a group of beautiful Caladiums, comprising many magnificent seedlings not yet in commerce. Particularly may be mentioned Barillet, rich scarlet-crimson centre and veins, pale-green edging; Onslow, large bronzy-crimson centre and veins, with green edge, the leaf covered with large rose-coloured spots, rendering it very attractive. Amongst named varieties now in trade the following will prove valuable additions to any collection: Meyerbeer, in the way of Belleymeii, bat having dark bronzy-crimson centre and veins; Max Kolb, light-gi'een ground, pale centre, heavily spotted with dark bronzy-crimson; Alfred Bleu, rich green leaf, with pure white spots and flesh-coloured centre. Imperatrice Eugenie, glaucous green, with elegant violet-rose centre; Dr Lindley, crimson centre, the green ground marked with rose blotches; Heine Victoria, style of Belleymeii, green veins and margin, spotted or marbled with crimson - this variety, along with Dr Lindley, received first-class certificates in London last season.

An attractive feature of the show was a large and beautifully flowered collection of annuals grown in pots from Messrs Vilinorin, Andrieux, & Co. The various colours blended together had a veiw pleasing effect. It is to be regretted that this lovely class of flowers receive so little attention, and are so seldom seen at our flower-shows.

M. Creste received a silver medal for a group of dwarf-grown Miguonette; this was remarkably well done in 6-inch pots, each averaging between fifteen and twenty heads of bloom.

Messrs Downie, Laird, & Laing, Edinburgh and London, exhibited new Coleuses, for which they were awarded the large silver medal. The finest in this lot were Albert Victor, Princess Royal, Baroness Rothschild, etc. Also silver medal for their new gold and bronze Geraniums Crown Prince, Prima Donna, J. W. Morris, and Imperatrice Eugenie.

The medal of honour given by the city of Paris for the best collection of spotted Pelargoniums was awarded to M. Dufoy, with a superb lot of about fifty varieties. These were very tastefully arranged, and formed one of the principal attractions of the show.

Fancy Pansies were numerous and well flowered in pots. The main object being brilliant and effective colours, fine forms and smooth edges seem to be disregarded.

Magnificent foliage-plants were exhibited by various growers, among which we noticed fine specimens of Cycas revoluta, Corypha Australis, Cycas circinalis, Latania Bourbonica, &c; also good examples of the Royal Horticultural Society's Coleuses of 1868.

In the afternoon the exhibition was honoured with a visit from the Emperor and Empress, who seemed to take a lively interest in the various articles brought forward for exLibition.
