Abstract
A new and distinct variety of pear tree which is somewhat remotely similar to the Bartlett, Forelle, and Comice pear trees (all unpatented), but from which it is distinguished as a large, vigorous, upright and hardy pear tree which is a regular and very productive bearer of large symmetrical fruit of good dessert quality having a thick, smooth, waxen, glossy skin; the skin having an occasional yellow ground color nearly all overspread, in maturity of ripening, with a burgundy red coloration, and the flesh being distinctly white.
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 pear tree, what I claim as new and desire to be secured by Plant Letters Patent is: 1. A new and distinct variety of pear tree substantially as illustrated and described and which is somewhat remotely similar to the "Red Angelo" pear tree, (U.S. Plant Pat. No. 4,315) but from which it is distinguished by having considerably more vigorous growth including longer shoots and leaves more tightly bunched and producing fruit which are consistently larger but less uniform with skin which is more smooth and heavily waxed, and which is characterized at maturity by a skin coloration of burgundy red with a yellow under coloration with medium size submerged red dots and which has distinctively white flesh.
