USPP26027P3 - Dischidia plant named ‘IDEAMINUBU’ - Google Patents

Abstract

A new and distinct Dischidia cultivar named ‘IDEAMINUBU’ is disclosed, characterized by strongly convexed, orbicularly shaped green leaves The new variety is a Dischidia, typically produced as an indoor or outdoor ornamental plant.

Description

Latin name of the genus and species: Dischidia nummularia.

Variety denomination: ‘IDEAMINUBU’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring whole plant mutation of an unpatented, unnamed variety of Dischidia nummularia.

The new variety was discovered by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, during 2004 in a commercial greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘IDEAMINUBU’ assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘IDEAMINUBU’ was first performed by cuttings during 2004 in a commercial greenhouse belonging to the inventor in Chonburi, Thailand. Access to all plants was restricted, as plants were kept in a location that is not open to the public. Through subsequent propagation by cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘IDEAMINUBU’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘IDEAMINUBU.’ These characteristics in combination distinguish ‘IDEAMINUBU’ as a new and distinct Dischidia cultivar:

• • 1. Orbicular shaped leaves.
  • 2. Strongly convex leaves
  • 3. Medium green foliage.
  • 4. Suitability for market use as an indoor or outdoor foliage plant in a container, for decorative purposes only.

PARENT COMPARISON

Plants of the new cultivar ‘IDEAMINUBU’ are similar to the unpatented, unnamed parent, Dischidia nummularia in most horticultural characteristics. The new variety, however, produces leaves that are darker green and smaller than those of the parent. Foliage arrangement of the new variety is different, and much more closely spaced than the parent variety. Additionally the leaf shape of the new variety is different than the parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘IDEAMINUBU’ are similar to the commercial variety Dischidia ‘Supha08’ U.S. Plant Pat. No. 21,202, in most horticultural characteristics. The new variety, however, produces larger, lighter colored leaves. ‘IDEAMINUBU’ also produces foliage in a different arrangement than ‘Supha08’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘IDEAMINUBU’ grown in a commercial greenhouse in Honselersdijk, Netherlands. This plant is approximately 8 to 9 months old, shown planted in a 10 cm. container.

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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
