1 Claim.

- The present invention relates to a new and dist1nct variety of rose plant, originating as a cross of two unnamed seedling varieties, having as its primary object to improve the color of the iiowers.

In this particular instance, I used as the seed parent a seedling of medium red color coming from the cross of Lucile Hill" (P1. Pat. No. 305) and Chieftain (P1. Pat. No. 150), and as the pollen parent a large, dark pink seedling, the result sought being to improve the coloring of the owers of the seed parent while retaining the other good qualities.

I succeeded in obtaining the color improvement of the flowers referred to, in combination with other novel characteristics in relation to the foliage.

Since Better Times (P1. Pat. No. 23) is such a well-known variety, comparison of this new rose with it may be made. As to the color of the owers, where the chief difference resides, Better Times is dark pink or cerise, while the new rose is Carmine to Spectrum Red. As to the leaflets, those on the present rose are long and narrow, except as to the end one as seen in the drawings; all Better Times leaflets are broad and are simply serrated and ovoid where those of the new rose are more deeply serrated and are irregularly serrated with only the end one ovoid in shape.

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

In the drawing:

Fig. 1 shows a specimen of the bud as the calyx breaks;

Fig. 2 shows the bud as the first pedal opens;

Fig. 3 shows the bloom when full blown;

Fig. 4 is a specimen of the foliage (upper surface);

Fig. 5 is another specimen of the foliage (under surface) and Fig. 6 is a section of the stem.

(All gures of the original drawing are made to the same scale.)
