This new yariety, originatl g stated. here, while resembling. pollen parent, .in that the... om b-0 h. a i i e d m ra n t-i1 two colors are quite noticeable and distinct. Z

Moreover,.ffGoldem-Rapture has very glossy foliage while this new variety is not at all glossy.

The thorns of this new variety are not as large as those of Golden Rapture and are dilferent in color; the plant is more resistant to disease, as determined by observation during develop ment; is very productive; does not drop its foliage easily, and develops long-pointed buds, so important in the type of roses designed for the cut flower trade and greenhouse forcing.

Other distinguishing characteristics reside in its free and abundant blooming habit, with large blooms occurring singly on strong stems, and of lon lasting quality when used as out flowers.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.
