As ucatan mailba 1936, Serial Thep'resent invention relates to a new and distinct variety of rose plant having as its primary objective the creation of a new type of decorative or bedding yellow rose. This objective was ar 5 rived at by. :a definite and repeated recrossing withinthe' progeny of Fontanelle (Souvenir of Claudius Pernet x Columbia) x Julien Potin (Souvenir 'de Claudius Pernet X an unnamed Pernetiana seedling). 1 1'0 .In-order .to producethe result sought and fix the characters, several generations of crosses were necessary, and from each of these in'turn'those seedlings were selected that came-nearest'to the ideal decorative or bedding type, cluster habit, fastness oicolor, and immunity offoliage-to diseases.

Generally describing my new origination, the plant in its finished form is vigorous and bushy, the foliage, dark green in color and's ornewhat crinkled and glossy,- being very tough. In order to make certain the satisfactory character of the results, the new variety was subjected to extensive tests over an extended period of time, both in Europe and at varied climatic points of the United States and Canada, and these tests proved it to be practically immune to diseases, particularly black spot and mildew. In this respect alone it is distinctly different from, and an exception among, yellow roses of the Pernetiana strain.

The drawing filed her with illustrates this new rose, but it is to be understood that owing to the fact that the color of the flower is very original or unusual, it is difiicult to describe by color charts and accurately paint or depict. It may be said, however, that in the Gravereaux system it approaches half-way between saffron and gold. Another way of describing this peculiar color is to say that it approximates that of a fresh dandelion in the early morning dew or might also be said to be like burnished brass, so shiny are its petals. A rather important feature resides in the fact that the color is uniform and fades less than that of any other yellow rose.

In respect to its flowering habit, the rose is characterized by its multiple clusters, the initial terminal bloom being quite large with lateral buds, often up to twelve or fifteen, flowering in succession with medium size blooms. The inflorescence is profuse and continuous.

I have asexually reproduced this new rose through the budding and grafting processes and it has always come true to form.

The following is a detailed description of this new variety, reference to color according with the Gravereaux color chart, {except where obviously the ordinary dictionarysdefinition is meant:

Wood:

New wood.Colorreddish. Barksmooth. Old w0od.-Colorbrown. Bark-smooth. Thorns: (Thorns are divided into thorns, prickles and short needles.)

Thorns.--Quantity-on main stalks from baseordinary, on laterals from stalkfew. Form-narrow; medium, hooked slightly downward. Color when young-red. Positionirregular.

Prickles-None.

Short needles-None.

The most important characteristics which, in combination, I deem to distinguish my new variety from all other decorative and bedding roses are:

1. The immunity of the foliage from the usual diseases found in yellow roses of the Pernetiana strain;

2. The novel and unusual yellow coloring of the flower;

3. The uniformity of the coloring and lack of tendency of the same to fade; and

4. The large size and number of the flowers growing in multiple clusters.

I claim:

A new and distinct type of decorative or bedding yellow rose plant, characterized by the immunity of its foliage to diseases, the distinctive yellow color of its flower, and the fastness of this color, substantially as shown and described.
