Title: Rhipsalidopsis plant named ‘Cebemma’

Description:
Botanical classification/cultivar designation:  Rhipsalidopsis gaertneri  cultivar Cebemma. 
     BACKGROUND OF THE INVENTION 
     The present Invention relates to a new and distinct cultivar of Rhipsalidopsis plant, botanically known as  Rhipsalidopsis gaertneri , and hereinafter referred to by the name ‘Cebemma’. 
     The new Rhipsalidopsis is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the breeding program is to create new compact Rhipsalidopsis with good postproduction longevity. 
     The new Rhipsalidopsis originated from a cross-pollination in April, 1995, of two proprietary seedling selections of  Rhipsalidopsis gaertneri , not patented. The new Rhipsalidopsis was discovered and selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlled environment in Odense, Denmark, in March, 1998. 
     Asexual reproduction of the new cultivar by cuttings taken at Odense, Denmark, since May, 1998, has shown that the unique features of this new Rhipsalidopsis are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the cultivar Cebemma have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cebemma’. These characteristics in combination distinguish ‘Cebemma’ as a new and distinct cultivar: 
     1. Compact, upright and outwardly spreading plant habit. 
     2. Freely branching growth habit. 
     3. Freely flowering with white-colored flowers. 
     Plants of the new Rhipsalidopsis differ from plants of the parent selections primarily in flower color as plants of the parent selections have pale pink-colored flowers. 
     Plants of the new Rhipsalidopsis can be compared to plants of the cultivar Auriga, not patented. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Rhipsalidopsis differed primarily from plants of the cultivar Auriga in flower color as plants of the cultivar Auriga had orange red-colored flowers. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Rhipsalidopsis. 
     The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Cebemma’. 
     The photograph at the bottom of the sheet comprises a close-up view of typical flowers of ‘Cebemma’. 
    
    
     DETAILED BOTANICAL DESCRIPTION 
     In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the above-mentioned photographs and botanical description were grown in Odense, Denmark in 9-cm containers in a glass-covered greenhouse. During the production of the plants, day temperatures were about 16 to 18° C. and night temperatures were about 16° C. Plants used were about one year old when the photographs and description were taken.
