Spathiphyllum plant named ‘Mara’

Abstract

A new cultivar of Spathiphyllum plant named ‘Mara’ that is characterized by upright strong leaves with undulate margins, minimal shoots and consistent flowering.

Description

Botanical classification: Spathiphyllum Schott.

Variety denomination: ‘Mara’.

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 ‘Mara’.

‘Mara’ is a hybrid that originated from the induced hybridization of the female or seed parent an unidentified Spathiphyllum Schott. (not patented) and the male or pollen parent an unidentified Spathiphyllum Schott. (not patented). The cultivar ‘Mara’ was selected by the inventor in 2000 as a single plant within the progeny of the stated cross in Melsen-Merelbeke, Belgium.

Asexual reproduction by tissue culture of the new cultivar ‘Mara’ was first performed in 2001 in Melsen-Merelbeke, Belgium. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Spathiphyllum cultivar ‘Mara’.

• • 1. Spathiphyllum ‘Mara’ exhibits upright strong leaves with undulate margins.
  • 2. Spathiphyllum ‘Mara’ exhibits minimal shoots.
  • 3. Spathiphyllum ‘Mara’ exhibits consistent flowering.

The closest comparison cultivar is Spathiphyllum ‘Alpha CD’. The new cultivar ‘Mara’ is distinguishable from ‘Alpha CD’ by the following characteristics:

• • 1. ‘Mara’ flowers earlier than ‘Alpha CD’.
  • 2. ‘Mara’ has a larger over all size than ‘Alpha CD’.
  • 3. ‘Mara’ has lighter green leaves than those of ‘Alpha CD’.
  • 4. ‘Mara’ has a larger spathe than ‘Alpha CD’.
  • 5. ‘Mara’ has a shorter and thicker spadix than ‘Alpha CD’.

The new cultivar ‘Mara’ is distinguishable from the unidentified male parent Spathiphyllum in having a more spreading habit and leaves that are less wavy. The new cultivar ‘Mara’ is distinguishable from the unidentified female parent Spathiphyllum in having a smaller size and leaves that are less wavy.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Spathiphyllum ‘Mara’. The plant in the photograph shows an overall view of a 27 month old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Spathiphyllum cultivar named ‘Mara’. Data was collected in De Kwakel, The Netherlands from 27 month old greenhouse grown plants in 30 cm containers. The time of year was Summer and the average temperature was 21 degrees Centigrade during the day and 18 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Mara’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
