Abstract:
A new and distinct variety of rose plant of the Miniature Climbing Class is provided which forms in abundance attractive double bright vermilion red blossoms. The climbing and vigorous vegetation of the new variety provides attractive ornamentation for parks and gardens. The blossoms are formed throughout the plant and are particularly long lasting.

Description:
SUMMARY OF THE INVENTION 
     The new variety of Miniature Climbing rose plant resulted as a mutation of unknown causation of the Meijikatar variety (U.S. Plant Pat. No. 4,682). The new variety of the present invention was discovered during the selective study of plants formed following the grafting of eyes of such variety. The form and color of the blossoms and foliage of the new variety are identical to those of the Meijikatar variety. However, the vegetation is of the climbing type rather than being dwarf and bushy. 
     It was found that the new variety of Miniature Climbing rose plant of the present invention possesses the following combination of characteristics: 
     (a) exhibits a climbing growth habit unlike the bushy growth habit of the Meijikatar variety, 
     (b) forms double bright vermilion red blossoms, and 
     (c) forms blossoms throughout the plant which are particularly long lasting. 
     The new variety well meets the needs of the horticultural industry for many usages. It is particularly well-suited for use as attractive ornamentation for parks and gardens. 
     The new variety has been found to undergo asexual propagation by a number of routes. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another. 
     The new variety has been named the Meiji Katarsar variety. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPH 
     The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety described herein were two years old and observed during November while grafted on Rosa froebelii understock and grown in greenhouses at Cannet-des-Maures, Var, France.

     DETAILED DESCRIPTION 
     The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology which precedes reference to the chart has been added to indicate the corresponding colors in common terms. The description is based on the observation of two year old specimens of the new variety during November while growing in greenhouses when grafted on Rosa frobelii understock at Cannet-des Maures, Var, France.
