Abstract
A new and distinct plant variety of the Cactaceae family is of the type known commercially as a "Christmas Cactus" and has a growth habit which is similar to that the "Gold Charm" variety (U.S. Plant Pat. No. 5,104) but which, nevertheless, differs, among other things, by having phylloclades with thicker and wider wings and thicker teeth in greater numbers per phyllocalde, and flowers which are sterile and have shorter tube laminating tepals, a perianth tube with longer major and minor elliptical axis, shorter tube attached stamens and larger diameter and shorter length styles.
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 similar to that of the "Gold Charm" variety but as modified by the combination of the characteristics which follow: (1) A more erect posture at maturity than the "Gold Charm" variety. (2) Phylloclades which, in comparison to the "Gold Charm" variety, have (a) wings with generally greater thickness and width dimensions, and (b) teeth with generally greater thickness dimensions and in a larger number per phylloclade, (3) Flowers which, in comparison to the "Gold Charm" variety, are sterile and have (a) a sepaloid tepal series with generally shorter length dimensions, (b) a tube laminating tepal series that has a larger number of tepals, (c) a perianth tube that at the throat has a generally longer major elliptical axis dimension and a generally longer minor elliptical axis dimension, (d) an androecium with filaments of the tube attached stamen group that have shorter length dimensions, (e) a gynoecium that has a style with a generally shorter length dimension and generally larger diameter and ovaries with generally longer minor axis dimensions at the distal end of the concavity.
