Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

We claim: 1. A new and distinct plant variety of the Cactaceae family as shown and described and which is mainly distinguished from its antecedents and known related varieties by a growth habit which is substantially like that of the "Gold Charm" variety but as modified by the combination of the following characteristics: (1) An erect growth habit, (2) Buds with (a) an ovary having a basic field during immaturity in which the color is usually dominated by a red hue, and in which, with further maturity of the bud, there is a development of random areas in which the color is dominated by a yellow green hue, and (b) petals having a basic field during bud immaturity in which the color is usually dominated by a red and/or pink hue and in which, with further maturity of the bud, there is a development of streaks in which the color is dominated by a yellow green and/or olive green hue, and (3) Sterile flowers having tepals with (a) a narrow marginal blade area that in color is dominated by a reddish orange, orange, orange yellow and/or pink hue, and (b) a center blade area that in color is dominated by a yellow hue and merges distally with the color in the basal area of the tepal blade.
