Description

DESCRIPTION OF THE PHOTOGRAPHS

(1) This new Phalaenopsis plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken in a greenhouse in Bleiswijk, the Netherlands, from 50-week-old plants in October 2022. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

(2) FIG. 1 shows the overall plant habit; including blooms, buds, and foliage of ‘PHA858376’.

(3) FIG. 2 shows a close-up of a flower of ‘PHA858376’.

(4) FIG. 3 shows an overhead view of the leaves of ‘PHA858376’.

DESCRIPTION OF THE NEW VARIETY

(5) The following detailed description sets forth the distinctive characteristics of ‘PHA858376’. Plants of the new Phalaenopsis have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, and day length, without, however, any variance in genotype. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined under 4000-6000 lux natural light in a greenhouse in Bleiswijk, the Netherlands. Observations and measurements were made in October 2022 on flowering plants which were planted in 12-centimeter (diameter) pots. After in vitro propagation, the plants were grown in nursery trays for 20 to 24 weeks, followed by transplantation into 12-centimeter (diameter) pots and grown in a greenhouse between 27° C. to 29° C. for 30 weeks, continued by a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks in a greenhouse of 21° C. Flowering occurs after 50 weeks in 12-centimeter pots.

Additionally, the leaf length of ‘PHA858376’ is longer than ‘PHALFAUF’.

(10) ‘PHA858376’ differs from the commercial variety ‘PHALFATYMO’ in that ‘PHA858376’ has flat flowers in lateral view, semi-erect to horizontal leaf attitude, and ovate lips of apical lobe, whereas ‘PHALFATYMO’ has concave flowers in lateral view, semi-drooping leaf attitude, and elliptic lips of apical lobe.
