Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Vanda spp. Jones ex R. Br.

Variety denomination: The inventive variety of Vanda disclosed herein has been given the variety denomination ‘SPCDW1705’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/1986, filed Aug. 9, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The new Vanda plant, ‘SPCDW1705’, is the result of a planned breeding program. ‘SPCDW1705’ originated as a seedling from the controlled pollination of Vanda ‘S13’ (not patented), the seed parent, with Vanda ‘NJR’ (not patented), the pollen parent. Both parents were developed by, and are owned by, the inventor and were never commercially released. The crossing was made by the inventor in his research greenhouse in Bangphra, Thailand in September of 1994.

The new variety was first selected in February of 1999, in a research greenhouse in Bangphra, Thailand belonging to the inventor. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1705’, assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual March of 2011 at a commercial laboratory belonging to the inventor in Bangphra, Thailand. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through six subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1705’ 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 ‘SPCDW1705’. These characteristics in combination distinguish ‘SPCDW1705’ as a new and distinct Vanda cultivar:

    • 1. Vanda ‘SPCDW1705’ exhibits numerous large flowers borne on an inflorescence which is carried slightly above the foliage; and
    • 2. Vanda ‘SPCDW1705’ exhibits broad, reniform to orbicular flower petals and broad ovate sepals, all of which are moderately to strongly overlapping; and
    • 3. Vanda ‘SPCDW1705’ exhibits petals and sepals moderately to strongly undulated margins; and
    • 4. Vanda ‘SPCDW1705’ exhibits light purple petals and sepals which are heavily dotted and blotched with a mixture of violet to violet-purple; and
    • 5. Vanda ‘SPCDW1705’ exhibits a labellum with a very dark violet-blue central lobe, and light yellow lateral lobes which are dotted with violet-blue.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in August of 2018 describe averages from a sample set of six specimens of six year-old ‘SPCDW1705’ plants grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. No artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1705’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
