1 Claim.

differing therefrom in point of color of the bloom, I

inasmuch as there appears to be nothing in greenhouse forcing varieties known by me which approaches it in color. Perhaps the nearest variety for comparison purposes is its pollen parent California, but with respect to the latter, the

blooms of the new variety have more petals, are better shaped, and open up more slowly. It does have growing habits somewhat similar to California, but they differ materially from other greenhouse forcing varieties and will therefore bring new blood into the latter.

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

The novel characteristics above referred to will become more apparent in the following detail description of the present rose, wherein color terminology accords with that of Ridgway's Color Standard, as and where designated; otherwise with usual dictionary significance:

Type: Tall; greenhouse; seedling: not tested outdoors.

Flower Locality where grown: Richmond, Indiana.

Flowers borne: singly to stem; irregular; on

strong, long stems.

Quantity of bloom: Abundant in greenhouse.

This description of a newly opened flower was made from a rose grown in a greenhouse during the month of March, 1942., at Richmond Indiana:

Inner petaloutside surface: base, Pale Lemon Yellow, Plate IV, shading to Alizarene Pink, Plate XIII; inside surface: base, Lemon Yellow, Plate IV, shading to Jasper Pink, Plate XIII.

This description was made from a rose that was 40 open for three days in a greenhouse in the month of April, 1942, at Richmond, Indiana:

.I claim: I

A new and distinct variety of rose plantof the hybrid tea class, characterized as to novelty by its growing habits when compared with other greenhouse forcing varieties, the, novel color of its blooms, number of petals, shape of the flower, and slow habit of opening of the same, substantially as shown and described.
