I claim:

A new and distinct variety of plum tree, characterized as to novelty by the natural dwarf habit of growth, rough and stocky trunk and branches, and small foliage of the tree, high productivity, early ripening and superior quality and sweet flavor of the fruit, the latter having a short stern, small pit cavity and small, smooth free stone, substantially as shown and described.
