Abstract: A new Chrysanthemum plant named `Syema Corbi` particularly distinguished by the large, two-toned red colored inflorescences, dark yellow-green foliage, nicely mounded plant habit with a late natural flowering season of about mid October.
Claim: What is claimed is:

1. A new and distinct variety of Chrysanthemum plant named `Syema Corbi` substantially as illustrated and described herein.
Description: Latin name of the genus and species of the plant claimed: Chrysanthemum.times.morifolium.

Varietal denomination: `Syema Corbi`.


The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum.times.morifolium, and hereinafter referred to by the variety name `Syema Corbi`.

`Syema Corbi` is a product of a planned breeding program. The new cultivar has large, two-toned red colored inflorescences, dark yellow-green foliage, nicely mounded plant habit with a late natural flowering season of about mid October.

`Syema Corbi` originates as a natural whole plant mutation of `Empire Emma`, U.S. Plant Pat. No. 20,196, and was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar in a controlledbreeding program in Alva, Fla. in November 2007. The parent cultivar `Empire Emma` has a little larger inflorescence size, little larger plant size, more bronze inflorescence color, and a natural season flowering that is a couple days faster.

The first act of asexual reproduction of `Syema Corbi` was accomplished when vegetative cuttings were propagated from the initial selection in December 2007 in a controlled environment in Alva, Fla.


Horticultural examination of plants grown from cuttings of the plant initiated in December 2007 and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for `Syema Corbi` are firmly fixed and areretained through successive generations of asexual reproduction.

`Syema Corbi` has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has been applied for in Canada on Mar. 19, 2010 (No. 10-6893). `Syema Corbi` has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.


The accompanying photographic drawing shows typical flower and foliage characteristics of `Syema Corbi` with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the newvariety.


The plant used for the photographs was about 16 weeks old grown in Monroeville, N.J. in an outdoor trial. One rooted cuttings grown in a nine inch pot with no terminal pinching of the apices. The photograph was taken in mid October 2010 inNew Jersey.

The plant descriptions and measurements were taken in Gilroy, Calif. in May 2010 under natural light. Plants were grown under conditions which approximate those generally used for potted chrysanthemum trials in a greenhouse. These plants usedin the descriptions were about 10 weeks old grown in 4.5 inch pots.
