1 Claim. 1

This invention relates to a new and distinct variety of rose plant resulting from a cross of the two known varieties of Charlotte Armstrong (Pl. Pat. #455) and Piccaninny.

The new rose is so completely distinguished from either of its parents that it may well be said that any similarity thereto is quite insignificant. The nearest to a similarity is found in the fragrance of its flowers relative to that of Piccaninny in that both are spicy, but Piccaninny is possessed of a penetrating fragrance, whereas that of this new variety is only moderate. Outside of this and a slight resemblance in the bark of the canes and amount of thorns, the new rose is definitely distinct from its parents and any other comparable variety of rose.

The primary features of distinction consist in its habit of growth and branching, its vigor, the size, shape, texture, and appearance of the leaves,

the shape of its open flowers and their color.

More specifically, three-day-open blooms are unique in two respects, i. e., the lateral margins of the petals are reflexed in such a manner as to frequently give to them a slender, linear-oblong appearance in outline. also prop each succeeding layer of petals against the petals adjacent on the outside so that, progressing toward the center of the flower, these petals approach a vertical position with increasing degree, until the center petals are often almost or entirely vertical in position. Such flowers are further unique in the degree of color constancy under a variety of weather conditions.

To the best of my knowledge, this new variety of rose contains the least amount of discernible Q blue pigment of any red rose available to commerce. The general color effect is near Currant Red (Wilson, Plate 821/1, page 167) in newly open flower, and remains this color, although becoming a somewhat intensified hue as the flower ages. Because of the appearance of the inner surface of the petal, there is a slight iridescence, which, viewed at certain angles, gives the effect of variations in color somewhat deeper than the shade above described.

In the drawing are shown specimens of the new variety at different stages of development of the bloom from bud to full-open flower and foliage from young to mature leaves.

Asexual reproduction shows that these characteristics hold true through succeeding propagations.

The following is a detailed description of the new variety, all reference to color being in accordance with the R. F. Wilsons Horticultural These lateral margins 2 Colour Chart, except where indicated to be in accordance with Ridgways Color Standard and Nomenclature:

so far.

Flower Locality where grown: Ontario, California. Flowers borne: Usually singly to stem; on normal, short to medium stems.

Quantity of bloom: Free; outdoors.

Continuity: Continuous during growing season. Fragrance: Moderate; spicy. Bud:

Peduncle.short to medium; medium heavy; medium stiff; medium rough; n'umerous gland-tipped cilia. Color-Deep Chrysolite Green, Plate XXXI (Ridgway) blotched with near Vandyk Red, Plate XIII (Ridgway) on side exposed to sun.

Before calyx breaks.-Sizesmall to medium.

Form-short; pointed; with foliaceous appendages, gland-tipped cilia, on the surface of the bud; with slender foliaceous parts extending beyond the tip of the bud equal to one-half or more of its length.

As cal /a: br ealcs.Color-Indian Lake, Plate 826, page 170, with Maroon, Plate 1030/1, page 185, shading. Inner surfacewith fine, woolly tomentum. Both margins have stipitate glands and wooly tomentum unless an adjacent sepal covers a margin, and then such covered margin is lined with woolly tomentum only.

As first petal opens.-Size-medium. Form medium length; ovoid. Col0r--Outside: near Indian Lake, Plate 826/1, page 170, with Maroon, Plate 1030/1, page 185, shad ings; inside: Chrysanthemum Crimson, Plate 824, page 169, with Maroon, Plate 1030/1, page 185, shading.

Opening-Opens up well.

Bloom:

Size.--When fully openmedium; 3%, inches to 4 inches. Petalaye.--Double from 28 to 3 2 petals plus 2 to 3 petaloids, arranged regularly: 1

Form-High center at first; becoming open with outer petals horizontal but with inside petals approaching a vertical position with increasing degree progressing toward center of flower. This change in petal direction is caused by the reflexing of the lateral margins of the petals in such a way as to cause them to have a slender linearoblong appearance in outline. Petals remaining at first loosely reflexed at lateral margins; becoming later, at maturity,

tightly reflexed at lateral margins. Petals: Thick; leathery; with inside velvety and outside shiny to satiny. 1

Shape.-Outsideobovate, with apex fiatI,

Intermediateobovate-cuneate with apex acute. Inside-narrowly obovate-cuneate with apex acute.

Col0r.Colors may be modified by being shaded with other colors.

This description of a newly'opened flower was made from a rose grown outdoors in the month of October, 1945, at Ontario, California:
