1 Claim. .(Cl. Plt.--21) The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by us by crossing the variety Chrysler Imperial (Plant Patent No. 1167) with the variety Charles Mallerin (Plant Patent No. 933).

As the result of this breeding, we have produced a new rose variety having the following unique combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which we are aware:

l) Vigorous, bushy and free-branching habits of plant growth;

(2) Moderately abundant foliage and good persistence thereof;

(3) Good balance and stretch of the flower stems;

(4) Large flower size, said flowers having very double petalage and good petal substance;

(5) A distinctive and attractive Deep, Dark Red general color tonality of the flowers;

(6) A strong combination of damask and tea lfragrance; and

(7) Long-lasting qualities of the flowers both on the plant and as cut flowers.

In comparison with its seed parent, Chrysler Imperial, the caliper diflerentiation between the base of the stems and their apex, or juncture of the stems with the peduncle, is substantially less in the case of our new variety than in this parent, and there is a substantially greater average length of the stems in the new variety so that the combination of these features gives a better appearance of balance between the stems and flowers than is found in this parent; the new variety has substantially greater petal substance which gives the flowers a longer-lasting quality both on the plant and when cut, this improved substance being readily evident by both touch and visual observation; after the outer flower petals have opened on the new variety, the intermediate petals usually are found with their tips folded over the tips of the remaining petals, which only rarely, if ever, occurs in the case of the parent variety;

'and the flowers of the new variety have a substantially deeper and darker color in both the bud and open flower stage than is the case of the flowers of Chrysler Im; perial, thereby being easily distinguishable at a glance.

As compared with the pollen parent, Charles Mallerin, the new variety is more heavily foliaged and the foliage is more persistent in comparison with the sparse and early deciduous foliage of this parent; the habit of growth is more regular and more well-balanced than the irregular and unbalanced habit of this parent, with the new variety branching freely and being quite bushy in comparison with the sparsely branching habit and open appearance of the plant of the parent variety; the new variety has greater flower petalage, ranging from 40 to 55 petals, as compared with 35 to 40 petals in the case of this parent; and the flowers of the new variety are full and high-centered at maturity, as compared with the flat and open flowers of Charles Mallerin.

Asexual reproduction of our new variety by budding, as performed at Chino, California, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of our new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of our new variety, with color terminology in accordance with the Nickerson Color Fan, published by Munsell Color Company, Incorporated, of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown outdoors during the month of c tober at Chino, California:

Color.-0uter petaloutside surface: Between Deep Purplish Red, Plate 10RP3/ l0 and Dark Red, Plate 2.5R3/7, with some overlay of Black or very Deep Purple on upper portion; inside surface: small spot of Brilliant Greenish Yellow, Plate 7.5Y9/8 about point of attachment, with remainder of lower half of petal near Deep Purplish Red, Plate 10RP3/10, and with upper half of petal being same basic color, but overlaid strongly with a very Deep Purple or Black. Intermediate petaloutside surface: between Deep Purplish Red, Plate 10RP3/l0 and Strong Purplish Red, Plate l0RP4/ 1'2; inside surface: small spot of Brilliant Greenish Yellow, Plate 7.5Y9/ 8 about point of attachment, with remainder of petal on lower 6 between Dark Red, Plate 2.5R3/7 and Deep Purplish Red, Plate 10RP3/ l0, and with upper 75 of petal near Deep Purplish Red, Plate 10RP3/ 10, but deeper with overlay of Deep Purple. Inner petalol1tside surface: near Dark Red, Plate 2.5-R3/7, but very slightly brighter and lighter; inside surface: very small spot of Brilliant Greenish Yellow, Plate 7.5Y9/ 8 at point of attachment, with remainder of petal having basic color of Deep Purplish Red, Plate 10RP3/l0, but overlaid with Dark Red, Plate 2.5R3/ 7; the velvety nap-like surface reflects different shades and intensities of Red or Purple depending on the angle of light incidence.
