#In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in Hensbroek, The Netherelands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and developement. During the production of the plants, day temperatures ranged from 17.5 to 30° C., night temperatures ranged from 18.5 to 24° C. and light levels were about five kilolux. Plants were pinched once and were about ten weeks from planting when the photographs and the description were taken. Botanical classification: Chrysanthemum×morifolium cultivar Dekspits. Commercial classification: Decorative spider-type Chrysanthemum typically grown as a single stem-type cut flower. Parentage: Female or seed parent.—Proprietary selection of Chrysanthemum×morifolium identified as code number 5000,97, not patented. Male or pollen parent.—Proprietary selection of Chrysanthemum×morifolium identified as code number 5003,60, not patented. Propagation: Type.—Terminal tip cuttings. Time to initiate roots, summer.—About 6 days at 20° C. Time to initiate roots, winter.—About 7 days at 20° C. Time to produce a rooted cutting, summer.—About 14 days at 20° C. Time to produce a rooted cutting, winter.—About 16 days at 20° C. Root description.—Fine and freely branching; light brown in color. Plant description: Appearance.—Herbaceous decorative spider-type cut Chrysanthemum; typically grown as a single stem-type; erect and strong flowering stems. Moderately vigorous. Flowering stem description.—Length: About 70 to 80 cm. Diameter: About 6 to 7 mm. Strength: Strong. Texture: Pubescent. Aspect: Erect. Branching habit: Plants are typically grown as single stems. Color: 146B. Foliage description.—Arrangement: Alternate. Length: About 9 to 11 cm. Width: About 6 to 9 cm. Apex: Cuspidate. Base: Attenuate. Margin: Lacerate. Texture, upper and lower surface: Pubescent; rough. Petiole length: About 3 to 5 cm. Color: Developing foliage, upper surface: Darker than 137A. Developing foliage, lower surface: 147B. Fully expanded foliage, upper surface: Between 137A and 147A. Fully expanded foliage, lower surface: 147B. Venation, upper and lower surfaces: 147C. Petiole, upper and lower surfaces: 147C. Inflorescence description: Appearance.—Decorative spider-type inflorescence form with quilled-shaped ray florets. Inflorescences borne on terminals above foliage. Disk and ray florets develop acropetally on a capitulum. Inflorescences not fragrant. Typically grown as a single stem-type. Flowering response.—Under natural conditions, plant typically flower in November in the Northern Hemisphere. At other times of the year, inflorescence initiation and development can be induced under short day/long night conditions (at least 13.5 hours of darkness). Plants exposed to long day/short night conditions after planting followed by photoinductive short day/long night conditions flower about 7.5 weeks later. Early and uniform flowering response. Postproduction longevity.—Cut inflorescences will maintain good substance and form for about 3.5 weeks. Quantity of inflorescences per flowering stem.—Only one per stem when grown as a single stem-type; if grown as a spray-type, about eight inflorescences per flowering stem. Inflorescence size.—Diameter: About 10 to 14 cm. Depth (height): About 4 to 5 cm. Inflorescence buds.—Height: About 1 to 1.5 cm. Diameter: About 1.2 to 1.5 cm. Shape: Oblate. Color: Close to 138A. Ray florets.—Length: About 6 to 7.5 cm. Width: About 6 to 8 mm. Shape: Quilled. Apex: Emarginate. Base: Fused; tubular. Margin: Entire. Texture, upper and lower surfaces: Smooth, glabrous. Number of ray florets per inflorescence: About 400 in numerous whorls. Color: When opening, upper and lower surfaces: 145B to 145C. Fully opened, upper and lower surfaces: 2D; towards the base, 150D. Disc florets.—No disc florets observed. Reproductive organs.—Androecium: Not observed. Gynoecium: Present on ray florets. Stigma length: About 5 mm. Stigma diameter: About 0.5 mm. Stigma color: Close to 155C. Seed/fruit.—Seed and fruit production has not been observed. Disease/pest resistance: Resistance to known Chrysanthemum pathogens and pests has not been observed on plants of the new Chrysanthemum.
