Title: Phalaenopsis orchid plant named ‘PHALFYTYO’

Description:
Genus and species:  Phalaenopsis  hybrid. 
     Variety denomination: ‘PHALFYTYO’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention relates to a new and distinct cultivar of  Phalaenopsis  plant, botanically known as  Phalaenopsis  hybrid of the Orchidaceae family, commonly referred to as moth orchid, and hereinafter referred to by the variety name ‘PHALFYTYO’. 
     The new  Phalaenopsis  plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, The Netherlands. The objective of this breeding program was to create a new short  Phalaenopsis  plant with attractive and small white flowers with a slightly red-purple center and unique red-purple lip, suitable for potted plant production. 
     The new  Phalaenopsis  plant ‘PHALFYTYO’ is a result of cross-pollination made by the inventor in August 2008 in Bleiswijk, The Netherlands of the proprietary female, or seed parent,  Phalaenopsis  hybrid ‘01-1789’ (unpatented) with the proprietary male, or pollen parent,  Phalaenopsis  hybrid ‘PHALDOMEO’ (U.S. Plant Pat. No. 25,682). 
     The new  Phalaenopsis  was selected by the inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse in Bleiswijk, The Netherlands in August 2011. Asexual reproduction of the new  Phalaenopsis  plant by meristem tissue culture since 2013 in Bleiswijk, The Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations. 
     Plant Breeder&#39;s Rights for this variety have been applied for in Europe on Apr. 25, 2017. ‘PHALFYTYO’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application. 
     SUMMARY OF THE INVENTION 
     The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands and can be used to distinguish ‘PHALFYTYO’ as a new and distinct variety of  Phalaenopsis  plant.
         1) Small, white flowers with a slightly red-purple center and unique red-purple lip;   2) 1 to 3 peduncles;   3) Peduncle is short and sturdy; and   4) Shape of the leaf is oblong.       

    
    
     
       DESCRIPTION OF THE PHOTOGRAPHS 
       This new  Phalaenopsis  plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken in a greenhouse in Bleiswijk, The Netherlands, from 50-week old plants in November 2017. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

     DESCRIPTION OF THE NEW VARIETY 
     The following detailed description sets forth the distinctive characteristics of ‘PHALFYTYO’. Plants of the new  Phalaenopsis  have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and day length, without, however, any variance in genotype. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined under 4000-6000 lux natural light in a greenhouse in Bleiswijk, The Netherlands. Observations and measurements were made in November 2017 on flowering plants which were planted in 9 centimeter (diameter) pots. After in-vitro propagation, the plants were grown in nursery trays for 18-20 weeks, followed by transplantation to 9 centimeter (diameter) pots and grown in a greenhouse between 27° C. to 29° C. for 25 weeks, continued by a cooling period of 6 weeks between 18° C. to 20° C. and 11 weeks in a greenhouse of 21° C. Flowering occurs after 42-weeks in a 9 centimeter pot.

     COMPARISON WITH PARENTAL LINES AND MOST SIMILAR VARIETIES 
     The female parent of ‘PHALFYTYO’, cultivar ‘01-1789’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made. 
     ‘PHALFYTYO’ differs from male parent plant ‘PHALDOMEO’ (U.S. Plant Pat. No. 25,682) in that ‘PHALFYTYO’ has white flowers, a white column and a slightly emarginated dorsal sepal apex, whereas ‘PHALDOMEO’ has purple flowers, a purple column and an obtuse dorsal sepal apex. 
     ‘PHALFYTYO’ is most similar to the commercial  Phalaenopsis  plants named ‘PHALCRYL’ (unpatented) and ‘PHALELENO’ (unpatented). ‘PHALFYTYO’ differs from the commercial variety ‘PHALCRYL’ in that ‘PHALFYTYO’ has a weakly spatulate lateral lobe shape, whereas ‘PHALCRYL’ has a spatulate lateral lobe shape. Additionally, ‘PHALFYTYO’ has smaller flowers and a shorter plant length (excluding pot) than ‘PHALCRYL’. 
     ‘PHALFYTYO’ differs from the commercial variety ‘PHALELENO’ in that ‘PHALFYTYO’ has a weakly spatulate lateral lobe shape, whereas ‘PHALELENO’ has a spatulate lateral lobe shape. Additionally, ‘PHALFYTYO’ has smaller flowers and a shorter plant length (excluding pot) than ‘PHALELENO’.
