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 28-week-old plant grown in a greenhouse in Bleiswijk, the Netherlands, in August 2022. 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 ‘AN2112420’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, the Netherlands. The plant history was taken on 28-week-old plants which were planted from tissue culture in 9-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in August 2022. 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 (R.H.S.) (2015).

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 110 degrees and 130 degrees; the spathe stands on a wiry peduncle about 1.0 cm to 3.0 cm above the foliage. Shape.—Cordate. Apex.—Mucronate.
