BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of x Doritaenopsis plant, botanically known as x Doritaenopsis (Doritis x Phalaenopsis), commonly referred to as Doritaenopsis and hereinafter referred to by the name ‘Untold Stories’.

The new Doritaenopsis plant is a product of a planned breeding program conducted by the Inventor in Nantou, Taiwan and Heemskerk, The Netherlands. The objective of the breeding program is to develop new fast-growing and freely flowering Doritaenopsis plants with good leaf shape and large flowers with unique and attractive patterns and coloration.

The new Doritaenopsis plant originated from a cross-pollination in May, 2012 in Nantou, Taiwan of x Doritaenopsis ‘Mei Dar Diamond’, not patented, as the female, or seed, parent with x Doritaenopsis ‘Luchia Pink’, not patented, as the male, or pollen, parent. The new Doritaenopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Heemskerk, The Netherlands in April, 2017.

Asexual reproduction of the new Doritaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since April, 2018 has shown that the unique features of this new Doritaenopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Doritaenopsis have 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 ‘Untold Stories’. These characteristics in combination distinguish ‘Untold Stories’ as a new and distinct Doritaenopsis plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Strong flowering stems.
  • 4. Strong leaves.
  • 5. Freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers.
  • 6. Flowers with fused labella, typically referred to as a “big lip” type.
  • 7. White-colored flowers that are densely covered with variable and coalescing dark red to purplish red-colored blotches and spots, also referred to as “cow spots”.
  • 8. Good postproduction longevity.

Plants of the new Doritaenopsis can be compared to plants of the female parent, ‘Mei Dar Diamond’. Plants of the new Doritaenopsis differ primarily from plants of ‘Mei Dar Diamond’ in flower color as plants of the new Doritaenopsis have white-colored flowers that are densely covered with variable and coalescing dark red to purplish red-colored blotches and spots whereas plants of ‘Mei Dar Diamond’ have purplish red-colored flowers. In addition, the labellum lateral and central lobes are fused in plants of the new Doritaenopsis whereas the lateral and central lobes of the labellum of plants of ‘Mei Dar Diamond’ are not fused.

Plants of the new Doritaenopsis can be compared to plants of the male parent, ‘Luchia Pink’. Plants of the new Doritaenopsis differ primarily from plants of ‘Luchia Pink’ in flower color as plants of the new Doritaenopsis have white-colored flowers that are densely covered with variable and coalescing dark red to purplish red-colored blotches and spots whereas plants of ‘Luchia Pink’ have violet-colored flowers. In addition, the labellum lateral and central lobes are fused in plants of the new Doritaenopsis whereas the lateral and central lobes of the labellum of plants of ‘Luchia Pink’ are not fused.

Plants of the new Doritaenopsis can be compared to plants of Phalaenopsis hybrida ‘Speechless Elegance’, disclosed in U.S. Provisional Patent application Ser. No. 62/705,003 and in a U.S. Plant patent application Ser. No. 17/339,967 filed concurrently. In side-by-side comparisons, plants of the new Doritaenopsis differ primarily from plants of ‘Speechless Elegance’ in flower shape as flower petals of plants of the new Doritaenopsis are not as overlapping as flower petals of plants of ‘Speechless Elegance’. In addition, petal blotches and spots of plants of the new Doritaenopsis are less distinct and more coalescing than petal blotches and spots of plants of ‘Speechless Elegance’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Doritaenopsis 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 Doritaenopsis plant.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Heemskerk, The Netherlands and under cultural practices typically used in commercial Doritaenopsis production. Plants were 18 months old when the photographs and description were taken. During the first twelve months of production of the plants, day and night temperatures averaged 27° C. During the final six months of production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 18° C. to 20° C. During the 18 months of production, light levels ranged from a minimum of 5,000 lux to a maximum of 10,000 lux.
