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 "Kris Kringle" variety (U.S. Plant Pat. No. 3,688) but which, nevertheless, differs, among other things, by having phylloclades with thicker and wider wings and with thicker and longer teeth, and sterile flowers with shorter perianth tubes and tube laminating and forming tepals that have generally wider blades.

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 "Kris Kringle" variety but as modified by the combination of the following characteristics: (1) An erect growth habit, (2) Phylloclades which, in comparison to the Kris Kringle variety, have (a) wings with greater thickness and width dimensions and (b) teeth with greater thickness dimensions and longer areole to apex dimensions, (3) Flowers which, in comparison to the Kris Kringle variety, are sterile and have (a) a sepaloid series of tepals with a smaller number of tepals that generally have shorter length dimensions and smaller maximum blade width dimensions, (b) a tube laminating series of tepals that generally have greater maximum blade width dimensions, (c) a tube forming series of tepals that generally have greater maximum blade width dimensions and perianth tubes that generally have shorter length dimensions, (d) an androecium with a smaller number of tube attached stamens, and (e) a gynoecium with a shorter style length dimension and longer ovary length dimension.
