BACKGROUND OF THE INVENTION

The genus Oncidium is one of the largest and most diverse within the orchid family; numbering more than 600 distinct species distributed throughout the American tropics and extending into South-Central America.

Many, if not most of the species within the genus, grow as epiphytes. The remaining species thrive growing as lithophytes or terrestrials. All exhibit a sympodial growth habit.

The first Oncidium hybrid was created in 1898 by a Mr. C. Vuylsteke and registered by the same. There are now over 7,600 unique hybrids of Oncidium as of June, 2022.

Oncidium hybridizing is accomplished through sexual methods. Asexual propagation of Oncidium is done in aseptic tissue culture from apical or axillary shoots.

The new cultivar was discovered within a group of sexually produced plants on May 18, 2017. The inventor selected Oncidium 21^st Scentury ‘Hula Girl’ from a population of 200 plants grown in 3.25 inch square black plastic pots, grown in a poly-film covered greenhouse in Mountain View, Hi. Oncidium 21^st Scentury ‘Hula Girl’ was re-flowered and submitted by the inventor to a commercial tissue culture laboratory in Bangkok, Thailand on Oct. 14, 2020 for asexual reproduction via tissue culture technique.

Other seedlings of the same varieties that were used to produce Oncidium 21^st Scentury ‘Hula Girl’ have been commercially available from others.

The characteristics of Oncidium 21^st Scentury ‘Hula Girl’ as described herein have demonstrated to be fixed and retained through successive generations of asexual reproduction. Oncidium 21^st Scentury ‘Hula Girl’ reproduces true to type. The characteristics are clearly distinguishable from the characteristics of those other plants. The inventor has reason to believe that Oncidium 21^st Scentury ‘Hula Girl’ is superior to other seedlings in floriferousness, fragrance and flower color.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of the new cultivar which in combination distinguish this Oncidium orchid as a new and distinct cultivar:

Flowers of the new cultivar are burgundy, soft pink and white in color. The sepals and petals are burgundy tipped cream distally. The labellum is soft pink centrally with glossy mid-lobes, bottom third white. The callus is soft pink and develops as a swelling in the lip terminating into many small diverging horns divided by a central crest about 0.5 centimeters (cm) long. The anther cap is cream in color. The column is burgundy throughout. The column wings are rectangular and translucent. The flowers are rigid and bear an intense, pleasing fragrance.

The natural horizontal spread is 3.2 cm; natural vertical spread is 4.7 cm; dorsal sepal width 0.7 cm; dorsal sepal length 1.7 cm; petal width 0.6 cm; petal length 1.4 cm; lateral sepal width 0.6 cm; lateral sepal length 1.7 cm; labellum width 1.5 cm; labellum length 1.7 cm.

The plant produces two branching inflorescences on first bloom with 80 flowers.

Inflorescence is a basal raceme, upright or arching, branching and approximately 50 cm long. The plant is relatively compact, and the size of the inflorescence is appropriate to the overall size of the plant and typical pot size for this cultivar.

There are generally six leaves per mature psuedobulb: two from the apex and four from the base. The apical leaves measure 35 cm long and are 5 cm wide. The leaves from the base of the pseudobulb measure 10-22 cm long and are 5 cm wide. Axillary leaves, or bracts, are not common below the leaves at the base of the psuedobulb. The shape of the leaf is lanceolate acuminate, and semi-conduplicate at the base. The texture and substance is slightly undulate and somewhat coriaceous. The plants of Oncidium 21^st Scentury ‘Hula Girl’ grow to maturity and flower in approximately 18 months.

Plants of the new cultivar have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment, such as temperature, light intensity, and day length, without any change in genotype.

The instant plant differs from parent cultivars in flower color and fragrance. The closest comparison to the new cultivar can be made to the parent cultivars used to create Oncidium 21^st Scentury ‘Hula Girl’. The original unpatented plant material; named Oncidium Aka Baby and Oncidium Pagans Scent possess the same general growth habit and speed to maturation, but lack the uniquely colored and intensely fragrant flowers of Oncidium 21^st Scentury ‘Hula Girl’.

DETAILED BOTANICAL DESCRIPTION

All color references are measured against the Pantone® Color System. Colors and numerical measurements are approximate, as plant growth and development depend on environmental conditions and cultural practices such as: light levels, temperature, water quality, fertilization formula and rate, among others, without any variance in genotype.

Plants used for this description are 24 months old in vivo and grown in 3.25 inch square, black plastic pots, grown in a poly-film covered greenhouse in Mountain View, Hi.

Day temperatures range from 75-85° F. and night temperatures range from 55-65° F. Light levels are approximately 2500 foot candles. This information reflects the annual variations for the area.
