     Applicant: Luc Remi Johan Pieters 
     Filed: Concurrently with this application U.S. Plant patent application Ser. No. 13/815,611 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Chrysanthemum  plant, botanically known as  Chrysanthemum×morifolium  and hereinafter referred to by the name ‘Red San Remo Runner’. 
     The new  Chrysanthemum  plant is a naturally-occurring whole plant mutation of  Chrysanthemum×morifolium  ‘Bronze San Remo Runner’, disclosed in U.S. Plant Pat. No. 23,319. The new  Chrysanthemum  plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘Bronze San Remo Runner’ in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in October, 2010. 
     Asexual reproduction of the new  Chrysanthemum  plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Staden-Oostnieuwkerke, Belgium in January, 2011. Asexual reproduction by cuttings has shown that the unique features of this new  Chrysanthemum  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Chrysanthemum  have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Red San Remo Runner’. These characteristics in combination distinguish ‘Red San Remo Runner’ as a new and distinct  Chrysanthemum  plant:
         1. Uniform, upright, broadly spreading and mounding plant habit; moderately vigorous to vigorous growth habit.   2. Freely branching habit; dense and full plant habit.   3. Uniform and freely flowering habit.   4. Large decorative-type inflorescences with dark red-colored ray florets.   5. Good garden performance.       

     Plants of the new  Chrysanthemum  differ primarily from the mutation parent, ‘Bronze San Remo Runner’, in ray floret color as plants of ‘Bronze San Remo Runner’ have greyed orange-colored ray florets. 
     Plants of the new  Chrysanthemum  can be compared to plants of  Chrysanthemum×morifolium  ‘Yellow San Remo Runner’, disclosed in a U.S. Plant patent application Ser. No. 13/815,611 filed concurrently. In side-by-side comparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of the new  Chrysanthemum  differ primarily from plants of ‘Yellow San Remo Runner’ in ray floret color. 
     Plants of the new  Chrysanthemum  can also be compared to plants of  Chrysanthemum×morifolium  ‘San Remo Runner’, not patented. In side-by-side comparisons conducted in Staden-Oostnieuwkerke, Belgium, plants of the new  Chrysanthemum  differed from plants of ‘San Remo Runner’ primarily in ray floret color as plants of ‘San Remo Runner’ had pink-colored ray florets. 
    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying photographs illustrate the overall appearance of the new  Chrysanthemum  plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Chrysanthemum  plant. 
       The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Red San Remo Runner’ grown in a container. 
       The photograph on the second sheet are close-up views of the upper and lower surfaces of typical inflorescences (left) and upper and lower surfaces of typical leaves (right) of ‘Red San Remo Runner’. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in 17-cm containers in an outdoor nursery in Staden-Oostnieuwkerke, Belgium and under conditions and cultural practices typical of commercial  Chrysanthemum  production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 5° C. to 15° C. Plants were 5.5 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
