1 claim. l

The present invention relates to a new and distinct variety of rose plant of the hybrid Wichuraiana class which was originated by me by crossing the variety Crimson Glory (Plant Patent No. 105) with the variety of Captain Thomas (Plant Patent No. 39E).

As the result of this cross, l have produced a new variety of rose which is uniquely distinguished from its parents, as well as from all other varieties of its class, as evidenced by the ioilorving combination of dominant characteristics:

(l) Large, single owers usually consisting of ve petals and rarely having any petaloids, as distinguished from the parent variety Captain Thomas which usually has from two to four petaloids;

(2) The remarkably uniformly colored owers having a general color tonality of deep lemon yellow in the fully open flowers, while the buds are the darkest shade of buttercup yellow, the flowers being much darker in color than the parent Captain Thomas, and being more like the color of the double-flowering variety High Noon (Plant Patent No. 194) (3) The very bushy, compact shrub or pillar rose habit of growth of the plant makes this new variety ideally suited for garden use, it being much more bush-like than Captain Thomas, although eventually attaining a height of eight feet or more;

(4) The stems and leaves of the new variety are remarkably free from anthocyanin pigment, and accordingly have practically no reddish or bronze coloration as is characteristic of the variety Captain Thomas";

(5) The buds of the new variety are also completely free of the reddish coloration that is characteristic oi Captain Thomas, and only rarely does the margin of one of the petals show a trace of light red color;

(6) The peduncle and stems of the new variety are much less pubescent and more glabrous than those of Captain Thomas;

(7) The foliage is very abundant and affords very good coverage in this shrub, and the leaves are more flat and less wrinkled than those of Captain Thomas, thereby producing an improved appearance which is still further enhanced by the large size of the dark green leaves;

(8) The relative freedom from thorns and the glabrous stem growth also make this variety an especially attractive shrub;

(9) The anther filaments are colored a very strong shade of Vermillion, thereby giving a very striking contrast to the deep lemon yellow openflower petals, as compared with the much lighter color of the stamen filaments of Captain Thomas";

(l0) 'Though Captain Thomas is highly resistant to mildew, it does frequently develop considerable mildew infection on the peduncles, whereas my new variety is even more resistant to mildew than "Captain Thomas," and rarely ever shows an infection on the peduncles; and

(il) The new variety is completely sterile, and hence sets no hips, as distinguished from the abundant hips and seeds produced by Captain Thomas which causes in the parent variety an unsightly appearance, with consequent decrease in flower production in the Fall season.

Asexual reproduction of the new variety by budding at La Canada, California, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawings show typical specimens of my new variety, one of said drawings showing in black-and-white a complete plant and depicting its general habits of growth, and the other drawing showing in color typical speci mens of the buds, flowers and foliage in different stages of development.

The following is a detailed description of my new variety, as based upon observations of specimens grown at La Canada, California, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart, except where general color terms of ordinary dictionary signficance are obvious:

Plate 5.

As first petal opens. Size medium. Form-medium length f pointed. Coloroutside: Chrome Yellcw,'Plate-605; inside: Lemon Yellow, Plate 4. Opening-opens up welll but is retarded from opening by cold weather.

This description of a newly opened flower was made from a rose grown outdoors in the month of June at La Canada, California:

Colon- Outside petal surface: Chrome Yellow. Plate 605; inside petal surface: Lemon Yellow, Plate 4.

This description was made from a rose that was open for three days outdoors in the month of June at La Canada, California:

Colon-Outside petal surface: Empire Yellow, Plate 603 at base, shading to Empire Yellow, Plate 603/1 towards petal tips; inside petal surface: Empire Yellow, Plate 603 at basel shading to Empire Yellow. Plate 603/1 towards petal tips.

General color effect-Empire Yellow, Plate Beinamen-Drop off cleanly; fading to very light yellow; fades more rapidly during hot and dry weather.

Flower Zongevz'ty.-On bush in garden--2 days in June. Cut owers grown outdoors kept at living-room temperatures- 2 days in June.

Reproductive organs stamens: Many; arranged irregularly about pistils; length variable from 1A inch to 3A inch.

Filaments: Most with anthers. Color-Near Vermillion, Plate 18.

A new and distinct variety of rose plant of the hybrid Wichuraiana class, substantially as herein shown and described, characterized particularly as to novelty by its bushy and compact habit of growth, by its abundant production of dark green, large, at and smooth leaves, by its glabrous stem growth and freedom from thorns, by its large, single type flowers and their absence of petaloids, by the uniform deep lemon yellow general color tonality of the flowers, by the dark buttercup yellow color of the buds and their substantially complete freedom of red coloration, by the freedom of anthocyanin pigment in its stems and leaves, by the strong Vermillion eolor of the anther filaments, and their resultant marked contrast with the color of the open owers, by the high resistance to mildew of both the foliage and the peduncles, and by its complete sterility and the absence of formation of hips and seeds.
