Abstract: A distinct cultivar of Anthurium plant named `Mars`, characterized by its upright plant habit; freely clumping growth habit; large, durable dark green leaves that are ovate in shape; large and numerous spathes that are positioned upright and beyond the foliage on strong and erect scapes; durable, glossy dark red spathes; year-round continuous flowering; good flowering under low light conditions; and good post-production longevity.
Claim: It is claimed:

1. A new and distinct cultivar of Anthurium plant named `Mars`, as illustrated and described.
Description: BACKGROUND OF THEINVENTION

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

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new Anthurium cultivars that have a freely clumping growth habit,strong and vigorous plant growth, attractive spathe color, numerous inflorescences and leaves, and good post-production longevity.

The new Anthurium originated from a cross by the Inventor in January, 1995 of the Inventor's proprietary Anthurium andreanum selection code No. 93-27 as the female, or seed, parent with the Inventor's proprietary Anthurium andreanum selectioncode No. 00-25 as the male, or pollen, parent. The cultivar `Mars` was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in February, 1998.

Asexual propagation of the new cultivar by tissue culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 the cultivar `Mars`. These characteristics in combination distinguish `Mars` as a new and distinct cultivar:

1. Upright plant habit.

2. Freely clumping growth habit.

3. Large, durable dark green leaves that are ovate in shape.

4. Large and numerous spathes that are positioned upright and beyond the foliage on strong and strong and erect scapes.

5. Durable, glossy dark red spathes.

6. Year-round continuous flowering.

7. Good flowering under low light conditions.

8. Good post-production longevity.

The new Anthurium can be compared to the female parent, the Inventor's proprietary selection code No. 93-27. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants ofselection code No. 93-27 in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the selection code No. 93-27.

2. Plants of the new Anthurium have more durable leaves than plants of the selection code No. 93-27.

3. Plants of the new Anthurium have larger spathes than plants of the selection code No. 93-27.

4. Plants of the new Anthurium have dark red-colored spathes whereas plants of the selection code No. 93-27 have pink-colored spathes.

The new Anthurium can be compared to the male parent, the Inventor's proprietary selection code No. 00-25. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants ofselection code No. 00-25 in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the selection code No. 00-25.

2. Plants of the new Anthurium have smaller and more durable leaves than plants of the selection code No. 00-25.

3. Plants of the new Anthurium have dark red-colored spathes whereas plants of the selection code No. 00-25 have dark pink-colored spathes.

The new Anthurium can be compared to the Anthurium cultivar `Elisabeth`, disclosed in U.S. Plant Pat. No. 9,704. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ fromplants of the cultivar `Elisabeth` in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the cultivar `Elisabeth`.

2. Plants of the new Anthurium have more durable leaves than plants of the cultivar `Elisabeth`.

3. Plants of the new Anthurium and the cultivar `Elisabeth` differ in spathe lobe coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective viewof a typical potted plant of the cultivar `Mars`. Leaf, spathe and spadix colors in the photograph may appear different from the actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe 2.5-year oldplants grown in 30-cm containers in Schipluiden, The Netherlands, in a glass greenhouse with an average day temperature of 25.degree. C. and an average night temperature of 19.degree. C.
