Plum tree
A plum tree which is of medium size, medium vigor, spreading, dense, and round-topped; foliated with medium size, obovate, medium pointed, medium thick, smooth-textured leaves having a crenate margin, a petiole medium in length and thickness, and small, irregularly opposite, globose glands; flowers from pointed, free buds of medium size and length; the flowers, of medium season, being medium size and white; and is a regular and very productive bearer of medium size, uniform, symmetrical, globose, semi-freestone fruit having dark purple skin, red flesh, and a brownish-yellow stone.

1. Field of the Invention
In the conduct of an extensive plant breeding program--on behalf of a commercial farming company, and in such company's experimental orchard located near Fresno, Fresno County, Calif.--I have originated a substantial number of new and distinct varieties of fruit trees, and which include the present variety of plum tree.
2. Classification of the Variety
The present variety of plum tree is embraced by Class 38, Plants, of the U.S. Patent Office MANUAL OF CLASSIFICATION.
3. Prior Varieties
Among existing varieties of plum trees which are known to me, and mentioned herein, are the Eldorado (unpatented) and the Angeleno (U.S. Plant Pat. No. 2,747).
ORIGIN OF THE VARIETYThe present variety of plum tree was originated by me as an open pollinated seedling of the Angeleno plum tree. A number of such seedlings were grown to fruition, in the aforesaid experimental orchard, under careful and continuing observation by me; the present variety being a selection from such seedlings which evidenced commercial promise.
ASEXUAL REPRODUCTION OF THE VARIETYAsexual reproduction of the variety was successfully accomplished, under my direction and in the aforesaid experimental orchard, by budding; such asexual reproductions, in maturity, having run true to the original tree in all respects.
SUMMARY OF THE VARIETYThe present variety of plum tree is, characteristically, of medium size, medium vigor, spreading, dense, and round-topped; foliated with medium size, obovate, medium pointed, medium thick, smooth-textured leaves having a crenate margin, a petiole medium in length and thickness, and small, irregularly opposite, globose glands; flowers from pointed, free buds of medium size and length; the flowers, of medium season, being medium size and white; and is a regular and very productive bearer of medium size, uniform, symmetrical, globose, semi-freestone fruit having dark purple skin, red flesh, and a brownish-yellow stone.
The present variety of plum tree is further characterized by semi-freestone fruit having red flesh in a season when nearly all other varieties of plum trees bear fruit having yellow flesh. Associated with the red flesh is relatively low acidity which enhances the fruit quality.
The present variety of plum tree is still further characterized by semi-freestone fruit which ripens about with the fruit of the Eldorado, and which it most nearly resembles, but, in comparative distinction, the globose fruit of the present variety has red flesh rather than the yellow flesh of the oblate fruit of the Eldorado.
