Description:
BOTANICAL CLASSIFICATION  
       [0001]      Phalaenopsis  sp.  
       VARIETY DENOMINATION  
       [0002]     ‘Sunrise Crystal’.  
         [0003]     The present invention relates to botanical classification/cultivar designation:  Phalaenopsis  Orchid cultivar Sunrise Crystal.  
       BACKGROUND OF THE INVENTION  
       [0004]     The present invention comprises a new and distinct cultivar of  Phalaenopsis  Orchid, hereinafter referred to by the cultivar name, Sunrise Crystal.  
         [0005]     The new cultivar is a product of a planned breeding program conducted by the inventor in Taiwan. The objective of the breeding program is to create new uniform pot-type  Phalaenopsis  Orchid cultivars having attractive flower coloration.  
         [0006]     The new cultivar breeder was Hou-Chih Lin. The new cultivar was discovered by the inventor from within the progeny of a cross-pollination of two identified proprietary selections of  Phalaenopsis  Orchid, not patented, on Apr. 19, 1999, in a controlled environment in Taiwan. Later, it was verified and registered in Royal Horticulture Society (R.H.S.) and had its variety name “P. Sunrise Crystal” on June, 2003.  
         [0007]     Asexual propagation by tissue culture in a laboratory in Taiwan has been used to increase the number of plants for evaluation and has demonstrated that the unique combination of characteristics as herein disclosed for the new  Phalaenopsis  Orchid are firmly fixed and are retained through successive generations of asexual reproduction.  
       SUMMARY OF THE INVENTION  
       [0008]     The following traits have been repeatedly observed and are determined to be basic characteristics which, in combination, distinguish this  Phalaenopsis  Orchid as a new and distinct cultivar: 
        1. Petal having a white main color and striped color pattern.     2. White-colored flowers with red purple-colored stripes and red purple-colored labellum.     3. Freely flowering habit.     4. Upright, freely branching and sturdy flowering stems.     5. Excellent postproduction longevity.        
 
         [0014]     Plants of the new cultivar differ primarily from plants of the parent cultivars in flower color.  
         [0015]     Plants of the new  Phalaenopsis  Orchid can be compared to plants of the cultivar P. Brother Girl (not patented), differing from plants of the cultivar P. Brother Girl in the following characteristics:  
         [0016]     1. Plants of the new  Phalaenopsis  Orchid are smaller than plants of the cultivar P. Brother Girl.  
         [0017]     2. Plants of the new  Phalaenopsis  Orchid are more freely flowering than plants of the cultivar P. Brother Girl.  
         [0018]     3. Plants of the new  Phalaenopsis  Orchid have more branches in inflorescence with more flowers per inflorescence than plants of the cultivar P. Brother Girl.  
         [0019]     5. Plants of the new  Phalaenopsis  Orchid have smaller flowers than plants of the cultivar P. Brother Girl.  
         [0020]     6. Plants of the new  Phalaenopsis  Orchid and the cultivar P. Brother Girl differ in labellum color. The former is red purple-colored and the latter is dark red purple-colored.
