To turn to Mr. Wm. Paul's seedlings, announced for 1865. Here we have promise of a departure from the stereotyped reds and scarlets. He appears to be trying back into old strains of a more genuine type and desirable colour. The nearer we approach the tints and forms of the best summer roses, combined with thorough perpetuality, the more likely are we to obtain that desirable flower, possessing all the points of a perfect rose. Their condensed description follows here: Elizabeth Vigneron, rosy pink, large, full, cupped, hardy, vigorous; Madame Emile Boyau, soft rosy flesh to blush, large, perfect, hardy, moderate; Prince de Joinville, showy rose, large, hardy, vigorous; Princess Lichtenstein, white, globular, large, full, hardy, flowering abundantly.
