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 of the "Alba" variety (U.S. Plant Pat. No. 3,574) but which, nevertheless, differs, among other things, by having phylloclades with thicker and wider wings and thicker teeth, and flowers which are sterile and have a larger number of tube laminating tepals that are also shorter in length and of a greater width and tube forming tepals which are also shorter in length and of a greater width.
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 "Alba" variety but as modified by the combination of the characteristics which follow: (1) A more erect posture at maturity than the "Alba" variety. (2) Phylloclades which, in comparison to the "Alba" variety, have (a) wings with generally greater thickness and width dimensions, and (b) teeth with generally greater thickness dimensions and longer areole to apex dimensions, (3) Flowers which, in comparison to the "Alba" variety, are sterile and have (a) a tube laminating tepal series that has a larger number of tepals, and tepals with generally shorter length dimensions and generally greater maximum blade width dimensions, (b) a tube forming tepal series that has tepals with generally shorter length dimensions and generally greater maximum blade width dimensions, (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 a smaller number of tube attached stamens and with filaments of the basally united 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 major and minor axis dimensions at the distal end of the concavity.
