Description

DESCRIPTION OF THE PHOTOGRAPHS

(1) This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 34-week-old plant grown in a greenhouse in Bleiswijk, the Netherlands, in November 2021. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

(2) FIG. 1 shows the overall plant habit, including blooms, buds, and foliage.

(3) FIG. 2 shows a close-up of the mature spathe.

(4) FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

(5) The following detailed description sets forth the distinctive characteristics of ‘ANTHHOZIF’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, the Netherlands. The plant history was taken on 34-week-old plants which were planted from tissue culture in 12-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November 2021. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (RHS) (2015).

Texture: Upper surface: Leathery and thick. Lower surface: Glossy, leathery, and thick. Venation: Pinnate veining; the mid-vein and primary veins (the veins that radiate out from the junction of petiole and leaf) protrude at the underside of the leaf blade. Venation color: Upper surface: RHS 144A. Lower surface: RHS 144B. Lobes.—Absent. Petiole.—Cross-section: Round. Diameter: 0.3 cm to 0.4 cm. Length: 11.0 cm to 14.0 cm for a mature leaf size. Color: Mature leaf: RHS 144B. Immature leaf: RHS 144C. Cataphyll color surrounding the petiole: Outside: RHS 144C. Inside: RHS 145D. Geniculum.—Length: 1.5 cm to 2.0 cm. Width: 0.4 cm to 0.5 cm. Color: RHS 144B. Inflorescence: Arrangement.—Single. Flowering habit (length of flowering season).—Continuous. Number of inflorescences per plant.—11 to 14. Fragrance.—Absent. Longevity of inflorescence on plant.—Over a year. Spathe: Buds.—The spathe is tightly rolled around the spadix and extrudes from the peduncle sheath. After the spathe is fully opened the peduncle elongates some extra centimeters. Arrangement.—Spathe angle with the peduncle is between 130 degrees and 150 degrees; the spathe stands on a wiry peduncle about 9.0 cm to 13.0 cm above the foliage. Shape.—Long ovate. Apex.—Abruptly acuminate. Base.—Rotundate. Texture.—Weakly blistered and wealdy glossy. Margin.—Undulated. Size.—Length: 9.0 cm to 12.0 cm. Width: 4.0 cm to 5.0 cm. Lobes.—Absent.

The spathe turns green after some weeks. Peduncle: Shape.—Erect. Cross-section.—Round. Length.—25.0 cm to 30.0 cm. Diameter.—0.3 cm to 0.4 cm. Color.—RHS 144B. Flowering time: General.—One small, rooted, untreated tissue culture plant of 8.0 cm tall will flower, depending on the season, after 32 to 36 weeks and 11 to 12 blossoms appear. More blossoms appear after some additional weeks so that a full flowering and commercial plant will have 13 to 14 white spathes. Smaller blossoms may occur on immature plants.

Angle of spadix tip with peduncle.—160 degrees to 180 degrees. Texture.—When the spathe is unfurling, the spadix is smooth. When the spadix matures, small stigmata protrude. The stigmata are evenly distributed around the spadix. The spadix matures from base to top, slowly giving the spadix a somewhat rough appearance. Color.—Immature: RHS 13C. Mature: RHS 155D. Ages to: RHS 144B. Flowers: Quantity per spadix.—110 to 140. Spadix flower arrangement.—Bisexual, rounded in cross-section. Shape.—Rounded. Size.—Length: 0.05 cm to 0.10 cm. Diameter (maximum): 0.10 cm. Color.—RHS 158D. Reproductive organs: Stamens.—Not visible. Pollen amount.—Absent. Pistil.—Quantity: 110 to 140. Length: Less than 0.01 cm. Color: RHS 158D.

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

(7) ‘ANTHHOZIF’ differs from the female parent plant ‘22570-02’ (unpatented) in that ‘ANTHHOZIF’ has white spathes, spadices that are white at the base, and leaf blades with no lobes, whereas ‘22570-02’ has pink spathes, spadices that are purple at the base, and leaf blades with lobes.

(8) ‘ANTHHOZIF’ differs from the male parent plant ‘26116-02’ (unpatented) in that ‘ANTHHOZIF’ has white, weakly blistered spathes and spadices that are white at the base, whereas ‘26116-02’ has pink, unblistered spathes and spadices that are pink at the base.

(9) ‘ANTHHOZIF’ differs from similar commercial variety ‘ANTHESZJA’ (U.S. Plant Pat. No. 29,713) in that ‘ANTHHOZIF’ has caudate leaf apexes and long ovate spathes with an obtuse angle of the distal part to the peduncle, whereas ‘ANTHESZJA’ has acute leaf apexes and ovate spathes with an approximately right angle of the distal part to the peduncle.

(10) ‘ANTHHOZIF’ differs from similar variety ‘ANTHDOMAQ’ (unpatented) in that ‘ANTHHOZIF’ has long ovate leaves with caudate apexes and long ovate spathes, whereas ‘ANTHDOMAQ’ has deltoid leaves with acuminate apexes and cordate spathes.
