Mr. John Saul sends us a colored plate of the Duchess of Edinburgh Rose, of which we recently gave a wood-cut in our pages, and Mr. A. Rolker & Sons, of New York, one of Rose, Duchesse de Vallambrosa. This is a salmon color shading to a blush, and if the flower comes out in this country just as represented here, is rather novel in tint. It appears to be a Hybrid Perpetual.
