Abstract
A new and distinct variety of plum tree which is a sport of the "Queen Ann" plum tree, but from which it is distinguished by producing large fruit of bright green coloration which are mature for harvesting and shipment approximately July 1 to July 5 in Kingsburg in the San Joaquin Valley of central California and which are slightly elongated with a superior ability to resist bruising.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described and illustrated my new variety of plum tree, what I claim as new and desire to be secured by Plant Letters Patent is: 1. A new and distinct variety of plum tree substantially as illustrated and described which is somewhat remotely similar to the "Queen Ann" plum tree from which it originated as a sport, but from which it is distinguished and characterized principally as to novelty by producing large fruit of generally bright green coloration which are mature for commercial harvesting and shipment approximately July 1 to July 5 in the San Joaquin Valley of central California and which further has noteworthy shipping and handling characteristics.
