Abstract

A new and distinct cultivar of Spathiphyllum is provided. The plant is medium to large size, full, symmetrical; suitable for production in a 15-25 cm pot from a single tissue culture produced microcutting; maintains proper growth habit and leaf shape at close pot spacing; grows very vigorously; branches early and freely; flowers naturally early and abundantly producing good quality inflorescences from the onset of flowering; has thick, strong peduncles and medium to large spathes with little green coloration, held relatively close to foliage.

Description

SUMMARY OF THE INVENTION
This invention relates to a new and distinct Spathiphyllum cultivar characterized by the following combinatin of repeatedly observed traits:
1. Medium to large size,
2. full and symmetrical growth habit,
3. growth habit and leaf shape maintained at crowded pot spacing,
4. very vigorous growth,
5. early and abundant branching,
6. early and abundant natural flowering,
7. good quality inflorescences from the onset of flowering,
8. thick, strong peduncles,
9. medium to large spathes with little green coloration, held relatively close to foliage;
and primarily selected for those characteristics being so selected from the progeny of the cross stated below in a cultivated area near Altha, Fla.
ORIGIN AND ASEXUAL REPRODUCTION
The new cultivar is a product of a planned breeding program carried out at Oglesby Plants International, Inc. near Altha, Fla. The female parent was a selected clone of Spathiphyllum hybrid, `Bond A`, (U.S. Plant Pat. No. 8,849) now marketed as Symphony™ and the male parent was a selected clone of Spathiphyllum hybrid, `Supreme`®, (patent not applied for). The cross was made in 1991. The plant was selected in 1993 and has since been reproduced by tissue culture in the vicinity of Altha, Fla., with the characteristics stated, found to be maintained through successive generations.
This new cultivar has been identified as Spathiphyllum `S18`. It is possible that other identification will be adopted in the trade, but the name selected will serve for the purposes hereof.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show as nearly true as it is reasonably possible, in a color illustration of this character, typical specimens of the plant parts of the new cultivar. The plant of `S18` was approximately 13 months from planting a single tissue culture produced microcutting in a 15 cm pot.
In the photographs:
FIG. 1 depicts the whole plant;
FIG. 2 illustrates the mature inflorescence;
FIG. 3 illustrates the top of a mature leaf; and
FIG. 4 illustrates the bottom of a mature leaf.
DETAILED DESCRIPTION OF THE NEW CULTIVAR
The following observations and measurements describe plants grown in Homestead, Fla., under shade house conditions. These observations and measurements were recorded near Altha, Fla., in December, 1997, from mature plants in 15 cm pots, about 13 months from planting a single tissue culture produced microcutting per pot. Fully developed organs on a dominant stem were used for measurements. Color values were determined on Dec. 2, 1997, under natural, indirect light of approximately 400-500 foot-candles. Color references are made to The R.H.S. Colour Chart, except where general color terms of ordinary significance are used.
`S18` has not been observed under all possible environmental conditions. The phenotype may vary with variations in environment and horticultural practices, such as temperature, light intensity, day length, fertilization, propagation method, etc., without any change in genotype.

COMPARISON WITH KNOWN CULTIVARS
The new cultivar can be compared to known cultivars `S2`, (U.S. Plant Pat. No. 10,786), now marketed as `Flower Power` and `S16`, (U.S. Plant Pat. No. 10,748), now marketed as `Showpiece`.
`S18` is distinguished from both cultivars by its fuller, wider and less upright growth habit; slightly lighter color leaves with more pronounced veins and wavy margins.
`S18` is further distinguished from `S2` by more abundant branching and smaller spathes, being closer to foliage.
`S18` is further distinguished from `S16` by the spathes, which generally do not bend back past maturity.
The new cultivar can also be compared to the parent cultivars `Bond A`, (U.S. Plant Pat. No. 8,849), now marketed as `Symphony` and with `Supreme` (patent not applied for).
`S18` is distinguished from `Bond A` by its larger size, more upright growth habit, more vigorous growth, earlier branching, earlier natural flowering, thicker and stronger peduncles, and larger spathes.
`S18` is distinguished from `Supreme` by its smaller size, fuller, more symmetrical and less upright growth habit better maintained at crowded pot spacing, earlier and more abundant branching, earlier and more abundant natural flowering, smaller leaves, and smaller less round spathes with more green coloration held closer to the foliage.
