assignor to Armstrong Nurseries, Inc.', Ontario, Galif., a corporation of California Application February 5, 1944, Serial No. 521,243 1 Claim. (01-. 47.-61)

This inventionrelates-to a new and distinct variety of rose plant; resulting from .the growing of seed from a cross of the two varieties J oanna Hill" and 'Crimson Glory.

It will be noted as this description proceeds on a tall, upright plant,;with single and at times several fiowers'to the stem, the buds sometimes attaining a length as much as three inches and being .of the type ofthat well known variety Charlotte Armstrong Specifically, this new rose has broad, leathery,

dull leaves, resistant to mildew, and the open blooms, which are usually cup-shaped and of moderate tea fragrance, have from fifteen to twenty-two petals, with from three to five petaloids arrangedirregularly.

The bloom ranges in size .from medium to large, usually measuring from three-and-one-half to four-and-one-half inches in diameter, and is of that shade of color popularly known as deep pink, which, technically, ranges principally from near PhloxPink to ,near Rose. Madder in the months of August and September in Southern California, The flowers earlier in the season are somewhat lighter in hue.

The plants vary in height from two-and-onehalf to four feet where grown in the garden, depending on the fertility of the soil.

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

The distinctiveness and novelty of this new variety may be recognized from the foregoing summaryand are .more particularly pointed out in the following detailed description in which color terminology accords with-that of the Robert E Wilson Horticultural Colour Charts: 'Iype: Fairly tall bush; outdoor; seedling; for

cut flowers and garden decoration. Class: Hybrid tea.

Breeding Seedling. T I

Flower Locality where grown: Ontario, California. Flowers borne: singly and at times several to stem; in irregular cluster; on normally, strong,

medium long stems.

Quantity of bloom: Free; outdoors.

Continuity: Continuous during growing season. Fragrance: Moderate; tea.

Bud:

Pedicel.Mediumlength; medium .heavy; erect; medium rough; few gland-tipped cilia. On some pedicels are a few hairs. Colornear Fern Green, Plate 0862/1, page 186,- Chart II.

- Before calyx breaks.-.S'ize-small to medium because sepals unfold and expose'the bud at a very early stage in its development when yet quite small. Form-short, pointed, without a conspicuous neck; usually 'without foliaceous appendages, tomentum, gland-tipped cilia on the surface of the bud; with slender, much out, bristle-like foliaceous parts extending .beyond the tip of the bud equal to. one-fourth or more of its length.

As calyx breaks.CoZornear Rose Madder, Plate 23, page 23, Chart I. Inner surfacewithfine, woolly tomentum, on margins of alternate sepals, lined with gland-tipped cilia, stipitate and sessile glands.

As first petal opens.-Size -medium. (Petal does not fold back to any extent until the bud has reached maturity though petals all loosen considerably from the initial tightly clasping state.) Form-short;

ovoid to globular. C0Zor-Outsidenear Crimson, Plate 22, page 22, Chart I. Inside-near Crimson, Plate 22, page 22, Chart 1, and gradually fusing into near Crimson, Plate 22/2, page 22,v Chart 1. Opening-opens up well; relatively rapidly is, when it is very large.

Bloom:

Size.When fully open-medium to large; approximately 3 /2 inches to 4 inches.

Petalage.Semi-double (2 or even three rows) from 15 to 22 petals; arranged regularly. 3 to 5 petaloids arranged irregularly.

Form.Cupped to high center atfirst; be-

coming open to cupped; petals .at first tightly flat; becoming later, at maturity,

loosely flat to cupped or rolled-outward.

Petals: Thick; with inside satiny and outside shiny.

Shape.utsideobovate, mucronate; sometimes scalloped apex with one or two notches occasionally. The center row of petals on some blooms are more scalloped than others. Intermediate-obcvate, mu-- cronate; scalloped at times with one or two i notches. Inside--obovate, mucronate; seldom irregular apex. On the petaloids of some blooms is a distinct ridge running from base to apex, off center, and often a lighter shade.

Color.-Colors may be modified by being penciled and shaded with other colors.

This description of a newly opened flower was made from a rose grown outdoors and allowed to open three days indoors, in August, 1943, at Ontario, California. The description of these petals was made from a rose grown in sandy soil:

Colon-Outside petal-outside surface-near Phlox Pink, Plate 625, page 77, Chart I, toward apex near Phlox Pink, Plate 625/1, page 77, Chart I. Inside surface-near Phlox Pink, Plate 625, then to edge near apex Phlox Pink, Plate 625/ 1, page 77, Chart I. At base of petal, near Aureolin, Plate 3-/2, page 3, Chart I. Intermediate petal-outside surface-this row of petals usually an even tone of near Phlox Pink, Plate 625, page 7'7, Chart I, on the outside and inside surfaces at base of petal near Aureolin, Plate 3/2, page 3, Chart I. Inner petaloutside surface-near Rose Madder, Plate 23/1, page 23, Chart I. Inside surface-near Rose Madder, Plate 23, page 2-3, Chart I, with more near Aureolin, Plate 3/2, page 3, Chart I, showing at base.

This description was made from a rose that was open for three days outdoors, in August, 1943, at Ontario, California. Made from a rose grown outdoors in a sandy soil. The temperature and humidity during the four days were: 86, 37; 86, 42; 88, 41.

Color.-Outside petal-outside surface-near Phlox Pink, Plate 625/ 1, page 77, Chart I, to near Phlox Pink, Plate 625/2, towards apex, page 77, Chart I. Penciling is quite pronounced on nearly all petals. Outdoors they become yellowish white about A" to from base when blooms are almost finished. Inside surface-very little differl ence from outside surface, except occasionally due to more exposure to sun the color may be a trifle lighter. Inside netaloutside surface-even hue of near Phlox Pink, Plate 625/ 1, page 77, Chart I.
