Roses in 1864.
In the section of purple, crimson, and violet colours, there are offered the following: Abbé Raynaud, Amiral La Peyrouse, Andre Leroy d'Angers, Eugene Verdier, H. Laurentius, Joseph Durand, Maréchal Suchet, Senateur Reveil. We select these first, because we think the most interesting accomplishment of the present season, as regards the distribution of new roses, will be found amongst those of the darkest shades of colour.

Roses Nouvelles.
M. Guillot fils, chemin de Pins, à la Guillotière, a livré, en novembre dernier, cinq gains de ses semis, appartenant aux hybrides remontants; ce sont:
Eugène Verdier, arbuste très-vigoureux; fleurs très-grandes, pleines, bien faites, superbe violet foncé. — 25 fr.

Translation:  New Roses. 
Mr. Guillot, the son, at chemin de Pins in the Guillotière, has, last November, sent out five of his seedlings, belonging to the hybrid perpetual class; these are:
Eugène Verdier, a very vigorous shrub; the flowers are very large, full, well formed, of a superb deep violet color. 25 fr.

New Roses.
...And now for the Hybrid Perpetuals.  We will take them according to the raisers.
Guillot fils.
20. Abbé Reynaud, dark slaty violet.
21.  Amiral La Peyrouse, dazzling superb red.
22.  Eugène Verdier, superb dark violet.
23.  Maréchal Suchet, beautiful crimson red, shaded with maroon.
24.  Paul de la Meilleray, purplish cherry rose.
Of these I should say that 20 and 22 are not colours that are suitable for us.  21 and 23 I should hope will be desirable varieties; while 24 with its large petals promises to be an acquisition.
