| Abstract: |
A new variety of a spider form chrysanthemum distinguished by its improved darker pink coloration when compared with its parent variety "Westland" (P.P. 4,589), particularly with respect to color retention, which is better than "Westland" which fades to a lighter pink more quickly. In all other respects, this sport of "Westland" is the same as its parent. |
| Claim: |
I claim:
1. A new and distinct variety of chrysanthemum plant, substantially as herein shown and described, characterized by the spider form of its flowers with quill-shaped ray florets which areof a darker color than that of its parent and having a much better color retention character. |
| Description: |
BACKGROUND OF THE INVENTION
My new cultivar of the spider type of chrysanthemum was discovered by me in 1976 as a sport in a field of "Westland" being grown by me in greenhouse at DeLier, Holland, for test and breeding purposes. The improved color of this sport and itsmuch improved color retention led me to reproduce the sport for further observation, which I did by means of cuttings, at DeLier. Subsequently, this new variety was propagated through many successive generations, from which it was observed that thenovel characteristics of the new plant would hold true from generation to generation and appeared to be firmly fixed. This new plant is now being propagated on a commercial scale, by means of cuttings, at Parrish, Fla., U.S.A.
DESCRIPTION OF THEDRAWINGS
This new chrysanthemum cultivar is illustrated by the accompanying drawings, of which sheet one is a print showing flowers of parent and mutant varieties which have been hand colored to show their true coloration, the new Dark Westland flowerbeing at the right; sheet two is a mechanical reproduction of a photoprint of the front side of typical leaves of the new plant; and sheet three is a mechanical reproduction showing the back side of the same leaves.
DESCRIPTION OF THE NEW PLANT
The following is a detailed description of my new variety of chrysanthemum based upon observations of greenhouse plants made during the winter of 1980 at West Chicago, Ill., U.S.A., with color designations according to The R.H.S. Colour Chartpublished by The Royal Horticultural Society of London, England.

Form.--Spider type with quill-shaped florets borne on a receptacle surrounded by an involucre of bracts.
Shape.--When bloom first opens -- Cup-shaped. When bloom matures -- Flat.
Size.--Medium. Diameter -- About 80 cm. Depth -- About 30 cm.
Borne.--As a cyme, being one of many carried in a racemose fashion on a strong, upright main stem.
Petalage:
Phyllaries.--About 12.
Florets.--About 150 in number.
Arrangement.--Imbricated.
Form.--Quill, with ragged and open apex and an entire type of margin.
Texture.--Soft.
Appearance.--Satiny.
Color.--Outer florets: Top Side -- 74D. Reverse Side -- 74C. Inner florets: Packed closely together and appearance to be darker, but are 74C from the tips to the yellow disc.

REPRODUCTIVE ORGANS
Stamens: None present.
Pistils:
Number.--One for each ray floret.
Styles.--4 to 6 mm. long.

Ovaries: Inferior, bicarpellate.
The particular distinction of this new cultivar resides in the darker coloration of its flowers when compared to the color of "Westland". This is very apparent at cool temperatures but is not as apparent at extremely warm temperatures. Thecolor retention is much better than that of "Westland", which fades to a lighter shade much more quickly. In all other aspects, this sport is the same as its parent "Westland".
