Abstract

A new and distinct cultivar of Spathiphyllum plant named ‘Mukjess’, characterized by its relatively compact, upright, outwardly arching and uniform plant habit; moderately vigorous growth habit; variegated leaves that are yellow green to greyed green-in color with dark green-colored venation and margins; if present, white-colored spathes are positioned above the foliar plane on strong and erect scapes; and good interiorscape performance.

Description

Botanical designation: Spathiphyllum Schott.
Cultivar denomination: ‘MUKJESS’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Spathiphyllum plant, botanically known as Spathiphyllum Schott. and hereinafter referred to by the cultivar name ‘Mukjess’.
The new Spathiphyllum plant is a product of a controlled breeding program conducted by the Inventor in Tiruporur, Tamil Nadu, India. The objective of the breeding program is to create new Spathiphyllum plants with unique leaf variegation patterns and good postproduction longevity.
The new Spathiphyllum plant is a naturally-occurring whole plant mutation of an unnamed variegated selection of Spathiphyllum Schott., not patented. The unnamed variegated selection (mutation parent) is a whole plant mutation of non-variegated Spathiphyllum Schott. ‘Gorgusis No. 1’, disclosed in U.S. Plant Pat. No. 6,964. The new Spathiphyllum plant was discovered and selected by the Inventor as a single plant from within a population of plants of the mutation parent in a controlled greenhouse environment in Tiruporur, Tamil Nadu, India on Sep. 21, 2012.
Asexual reproduction of the new Spathiphyllum plant by divisions in a controlled environment in Tiruporur, Tamil Nadu, India since Jan. 12, 2014 has shown that the unique features of this new Spathiphyllum plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Spathiphyllum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental 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 ‘Mukjess’. These characteristics in combination distinguish ‘Mukjess’ as a new and distinct Spathiphyllum plant:
    • 1. Relatively compact, upright, outwardly arching and uniform plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Variegated leaves that are yellow green to greyed green-in color with dark green-colored venation and margins.
    • 4. If present, white-colored spathes are positioned above the foliar plane on strong and erect scapes.
    • 5. Good interiorscape performance.
Plants of the new Spathiphyllum differ from plants of the mutation parent selection in the following characteristics:
    • 1. Plants of the new Spathiphyllum are more compact and slower-growing than plants of the mutation parent selection.
    • 2. Leaves of plants of the new Spathiphyllum are smaller than leaves of plants of the mutation parent selection.
    • 3. Plants of the new Spathiphyllum have variegated leaves that are yellow green to greyed green-in color with dark green-colored venation and margins whereas plants of the mutation parent have variegated leaves that have large random and irregular sectors that are white, greyed green or dark green in color with green and white-colored midveins.
Plants of the new Spathiphyllum can also be compared to plants of Spathiphyllum Schott. ‘Domino’, disclosed in U.S. Plant Pat. No. 9,944. In side-by-side comparisons, plants of the new Spathiphyllum differ from plants of ‘Domino’ in the following characteristics:
    • 1. Plants of the new Spathiphyllum are more compact and slower-growing than plants of ‘Domino’.
    • 2. Plants of the new Spathiphyllum are not freely clumping whereas plants of ‘Domino’ are freely clumping.
    • 3. Leaves of plants of the new Spathiphyllum are broader and more uniform in shape than leaves of plants of ‘Domino’.
    • 4. Leaves of plants of the new Spathiphyllum are not as undulate as leaves of plants of ‘Domino’.
    • 5. Plants of the new Spathiphyllum have variegated leaves that are yellow green to greyed green-in color with dark green-colored venation and margins whereas plants of ‘Domino’ have variegated leaves with white and green-colored random and variable sectors with green and white-colored midveins.
    • 6. Plants of the new Spathiphyllum produce fewer but larger inflorescences than of plants of ‘Domino’.
Plants of the new Spathiphyllum can also be compared to plants of Spathiphyllum Schott. ‘Spadulu’, disclosed in U.S. Plant Pat. No. 22,599. In side-by-side comparisons, plants of the new Spathiphyllum differ from plants of ‘Spadulu’ in the following characteristics:
    • 1. Plants of the new Spathiphyllum are more compact and slower-growing than plants of ‘Spadulu’.
    • 2. Plants of the new Spathiphyllum are not freely clumping whereas plants of ‘Spadulu’ are freely clumping.
    • 3. Leaves of plants of the new Spathiphyllum are smaller than leaves of plants of ‘Spadulu’.
    • 4. Plants of the new Spathiphyllum have variegated leaves that are yellow green to greyed green-in color with dark green-colored venation and margins whereas plants of ‘Spadulu’ have non-variegated leaves that are dark green in color.
    • 5. Plants of the new Spathiphyllum produce fewer inflorescences than of plants of ‘Spadulu’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Spathiphyllum plant showing 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 Spathiphyllum plant.
The photograph on the first sheet (FIG. 1) is a side perspective view of a typical young plant of ‘Mukjess’ grown in a container and is about 15 months from planting.
The photograph on the second sheet (FIG. 2) is a side perspective view of a typical older plant of ‘Mukjess’ grown in a container and is about 24 months from planting.
The photograph on the third sheet (FIG. 3) is a close-up view of a typical inflorescence of ‘Mukjess’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the late winter to mid-summer in 20-cm containers in shadehouses in Miami, Fla. and Fort Worth, Tex. and under cultural practices typical of commercial Spathiphyllum production. During the production of the plants, day temperatures ranged from 16° C. to 35° C. and night temperatures ranged from 8° C. to 22° C. Plants were two years from transplanting rooted young plants when the detailed description was 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.
