BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum and hereinafter referred to by the name ‘AN2494662’.

The new Anthurium plant is a product of a controlled breeding program conducted by the Inventor in Bleiswijk, The Netherlands. The objective of the breeding program is to create new freely-clumping Anthurium plants with attractive, durable and glossy spathes.

The new Anthurium plant originated from a cross-pollination made by the Inventor in March 2011 in Bleiswijk, The Netherlands of a proprietary selection of Anthurium andreanum identified as code number 07-016671-0011, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 05-011081-0001, not patented, as the male, or pollen, parent. The new Anthurium was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bleiswijk, The Netherlands in March 2013.

Asexual reproduction of the new Anthurium plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since June, 2015 has shown that the unique features of this new Anthurium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Anthurium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AN2494662’. These characteristics in combination distinguish ‘AN2494662’ as a new and distinct Anthurium plant:

- 1. Upright to outwardly arching and uniform plant habit.
- 2. Freely clumping growth habit; bushy and dense plants.
- 3. Narrowly cordate dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Inflorescences that are positioned within to slightly above the foliar plane on strong and erect scapes.
- 6. Broadly cordate dark reddish orange-colored spathes and white and yellow-colored spadices.
- 7. Durable spathes that impart good inflorescence longevity.

Plants of the new Anthurium differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Anthurium are more freely clumping than plants of the female parent selection.
- 2. Spathes of plants of the new Anthurium are flat to slightly convex whereas spathes of plants of the female parent selection are concave.

Plants of the new Anthurium differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Anthurium are more freely clumping than plants of the male parent selection.
- 2. Leaves of plants of the new Anthurium are narrowly cordate in shape whereas leaves of plants of the male parent selection are ovate to cordate in shape.
- 3. Spathes of plants of the new Anthurium are smaller than spathes of plants of the male parent selection.

Plants of the new Anthurium can also be compared to plants of Anthurium andreanum ‘Anthfablo’, disclosed in U.S. Plant Pat. No. 30,547. In side-by-side comparisons, plants of the new Anthurium differ primarily from plants of ‘Anthfablo’ in the following characteristics:

- 1. Spathes of plants of the new Anthurium are not as rugose as spathes of plants of ‘Anthfablo’.
- 2. Spadices of plants of the new Anthurium are straighter than and not as curving as spadices of plants of ‘Anthfablo’.
- 3. Spadices of plants of the new Anthurium are not as tapering as spadices of plants of ‘Anthfablo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Anthurium. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Anthurium.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical plant of ‘AN2494662’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of typical inflorescences of ‘AN2494662’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 12-cm containers in Bleiswijk, The Netherlands during the late autumn in a glass-covered greenhouse. Plants were grown under conditions and practices which approximate those generally used in commercial Anthurium production. During the production of the plants, day and night temperatures ranged from about 19° C. to 22.5° C. and light levels ranged from 100 μmol to 200 μmol. Plants were ten months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
