1 Claim.

new variety, in the order of their importance may be noted:

(a) The delectable flavor and juiciness of the fruit, as compared with other peach varieties ripening near its season, that is within two weeks earlier or later.

(1)) Its low chilling requirement in combination with late ripening, when compared with other ciated when it is understood that this low chilling requirement allows the variety to set a good crop of well-flavored fruit each year, where other late-ripening varieties often are without fruit following mild winters in southern California.

Distinct difference as to size and shapesome globose and quite symmetrical, some depresso-globose, and others asymmetrical tending toward turbinate. I

(d) Moderate toughness of the skin of the fruit and somewhat light color, as compared with many of the so-called yellow-fleshed peaches, and the extent of the area and intensity of the blush in pink and reddish tones, varying from peach to peach and depending apparently on the amount of sunlight which the fruit received.

(e) The orange-yellow color of the flesh, considerably deeper than most of the so-called yellow-fleshed peaches; and the considerable red color around the pit, which latter is somewhat above average size.

(1) Unusually shallow stem cavity and the accompanying characteristic of the fruit hanging on the tree very well after ripening, sometimes even until after starting to decompose.

(g) Average ripening season, from September 25 to October (in southern California), said season varying with the mildness of the winter preceding the crop and being always late after a severe winter.

(h) Absence of tendency to oxidize (turn brown) to any extent after being cut, even after being exposed six to eight hours.

Asexual reproduction of the new variety shows 1t1he above characteristics to be established and xed.

The following is a detail description of this new variety, according with observations of specimens grown at Ontario, California, color terminology thereof referring to Robert F. Wilson Horticultural Charts:

Tree: Medium size; vigorous; upright; spreading; open; vase formed; productive; regular bearer.

Flower buds.Half hardy; medium to small size; medium to short length; conic to pointed; plump; free.

Flowers-Dates first and full bloom-March 18 and April 2, respectively, in 1943. Early compared with other varieties near same season of ripening; medium to small size; Pink.

Form.Variable; symmetrical to unsymmetrical; at times compressed transversely toward suture. Some fruits have a pronounced beak at the apical end, other fruits are almost completely round, except for the stem cavity, and still other fruits are intermediate between these two types, some of them having a pronounced lip on one side of the suture, and on others the lips are not pronounced.

Suture-Line distinct; shallow to deep; ex-

tends from base to apex; has slight depression beyond pistil point at times. Sometimes this line does extend beyond apex to dorsal surface, and about /3 length of fruit.

Ventral surfa'ce.variably rounded. Lips, unequal when present. .Ventral surface, some fruits do not show any lip whatever, others have a definite lip from center of fruit to apex.

Stem cavity.-Circular to elongated in suture plane with suture showing on one side. Depth, to breadth, to 1 markingsat times pencilling (see skin color).

' Base-Rounded I to truncate.

A'pewr-Some fruits have little apex, or even a pistil point; while others have an elongated apex, and pistil point oblique,

Stem.Length, about /4"; medium stout;

glabrous. Adherence to stonestrong to medium. Skin.---Medium tender; slightly astringent;

tenacious to flesh. Tendency to crack-- 1 Flesh.--Co1ornear Maize Yellow, Plate 607, Chart I, page 69. Surface of pit cavitynear Jasper Red, Plate 018, Chart II, page 107.

AmygdaZin.-Scant; juice moderate, rich.

Tamra-Medium firm; fine; meaty.

Fibres-Few; fine; tender.

Hyena-Somewhat uneven; earliest at lip.

Aromw.Slight.

Eating quality-Very good.

Fibres-Short; parts from fiesh smoothly.

tree; late ripening season and lack of tendency of the flesh to oxidize, substantially as shown and described.
