VARIETAL DENOMINATION  
       [0001] ‘98238-3’ 
       BOTANICAL CLASSIFICATION  
       [0002] Begonia Elatior  (Begonia)  
       BACKGROUND OF THE INVENTION  
       [0003] The present invention comprises a new and distinct cultivar of  Begonia elatior  known by the varietal name ‘98238-3’. The new variety was discovered in Aalsmeer, Netherlands, in 1998. The new variety is a product of a planned breeding program and is a cross of an unnamed, unpatented variety of  Begonia tuberosa  (female) and an unnamed, unpatented variety of  Begonia socotrana  (male). The breeding program is directed to establishing various phenotype characteristics. The new variety differs in its flower color and its double flowers as compared to its parents. The new variety was first asexually reproduced by cuttings in Aalsmeer, Netherlands. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.  
       [0004] The new variety, when grown in a glass greenhouse has a response time for rooting from a terminal cutting of 14-18 days. 
     
    
    
     DESCRIPTION OF THE DRAWING  
     [0005] The accompanying photographic drawing illustrates the new variety, with the color being as nearly true as is possible with color illustrations of this type. 
    
    
     DESCRIPTION OF THE PLANT  
     [0006] The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions by cuttings in a controlled greenhouse environment. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
