Title: Miniature rose plant named Ruihonzev

Description:
SUMMARY OF THE INVENTION 
     The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was originated by me by crossing as the seed and pollen parents unnamed and unpatented seedlings of my creation. The varietal denomination of the new variety is `Ruihonzev`. 
     Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its light and medium pink flowers borne on a plant particularly suited for production of flowering pot plants. The new variety can be reproduced through propagation by cuttings, grafting, budding, and micropropagation. Flowers of the new variety are long lasting on the plant. Asexual reproduction by budding, grafting and propagation of cuttings of the new variety as performed in Hazerswoude, Holland, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. 
    
    
     BRIEF DESCRIPTION OF ILLUSTRATIONS 
     The accompanying illustrations show typical specimens of the vegetative growth and flowers of the new variety in different stages of development depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression, including colors, may vary depending upon growing conditions, such as under different climate, soil, and cultivation conditions. 
    
    
     One accompanying illustration is of a plant of the new variety of miniature rose showing flowering and growth habit; but the colors depicted are not true because of bright light reflection on the flowers. The other illustration shows details of the new miniature rose variety illustrated in colors believed to more accurately depict flower coloration. 
     DETAILED DESCRIPTION OF THE NEW VARIETY 
     The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.) and horticultural terminology in accordance with standard terminology used in UPOV-approved horticultural guidelines. The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart. 
     Parentage: Seedling. 
     Seed parent.--Unnamed seedling. 
     Pollen parent.--Unnamed seedling. 
     Class: Miniature. 
     As can be seen in the accompanying illustrations, one illustration shows one sample of flowering plant of the new variety depicting the pot plant habit of growth and flowering. Since flowering is nearly continuous, this floriferous variety can remain attractively in bloom for long periods when given proper care and culture. 
     The other illustration shows details of the new variety. In the illustration there is shown the top of a young shoot, 1; compound three and five leaflet leaves, 2, and 3, respectively; a stem, 5; buds, 6 and 7; a flower, 8, about one-half open; and a flower 9, fully open. Also shown are portions of flower stems 10, 11 and 12, with reproductive organs. 
     The following further horticultural observations were made of specimens grown under glass in Holland. 
     Flower 
     Blooming habit: Nearly continuous. 
     A. Bud: 
     (1) Size.--Small. 
     (2) Form.--Ovate (before separation of sepals); broad ovoid after sepals part.

     (4) Arrangement.--Regularly arranged, imbricated. 
     (5) Petaloids in center.--Few.
