Disclosed is a new and distinct variety of Spathiphyllum which is particularly distinguished by having rapid growth and a propensity to sucker as compared to related plants. The plant is a selection from the cross Mauna Loa `Alice`.times.floribundum (seed parent) and wallisi (pollen parent).

The invention comprises a new and distinct cultivar of Spathiphyllum known 
as Spathiphyllum hybrida `Lynise`. 
The new cultivar is a product of a planned program carried out by Bond 
Caldwell of Babylon Nursery, Brooksville, Fla. The parents are (Mauna Loa 
`Alice`.times.floribundum) (seed parent) and wallisii (pollen parent). The 
cultivar was discovered and selected from the progeny of the stated cross 
by Mr. Caldwell. Asexual propagation by division (Mr. Caldwell) and by 
tissue culture (Hartman's Plants, Inc.) was used to increase the number of 
plants available for evaluation and to demonstrate the stability of the 
distinguishing combination of characteristics from generation to 
generation. 
The following observations, measurements and values describe plants grown 
in Brooksville under greenhouse conditions that closely approximate those 
generally used in horticultural practice. 
The following traits have been repeatedly observed and are characteristics 
that in combination distinguish Spathiphyllum hybrida `Lynise` from other 
Spathiphyllum of the general type i.e. Mauna Loa `Supreme` and `St. 
Mary's`. Mauna Loa `Supreme` and `St. Mary's` are trademarks of Olgesby 
Lab, Inc. 
DISTINCTIONS 
1. Medium large Spathiphyllum of smaller size than `St. Marys's` and 
approximately the same size but somewhat taller than `Supreme` being 
approximately 0.7 meters to 1.0 meters in height and approximately 1.0 
meters to 1.4 meters in width when fully mature in a 15 gallon pot. 
2. White flowers, the spathe being approximately 20 cm to 28 cm in height 
and approximately 9.0 cm to 12.00 cm in width standing above the soil 
surface 0.9 meters to 1.1 meters to the base of the spathe in a 15 gallon 
container. 
3. Closely spaced prominant veins giving a more corragated appearance than 
`Supreme` or `St. Mary's`. The veination pattern described above is 
apparent in all of the leaves of mature size on `Lynise` without 
significant exception, although there may be a few gaps in the pattern in 
some of the leaves. Some cultivars such as `supreme` may have a few leaves 
that partially approximate the pattern. When the plants are viewed as a 
whole, however, they are clearly distinguishable. 
4. The petiole, midrib and primary veins are stiff enough to resist wilting 
due to moderate water stress as compared to `Supreme`. 
5. The lower leaves are rounder than `Supreme` giving the mature plant a 
fuller appearance. 
6. Lynise` suckers more than `Supreme`. 
7. Lynise` does not pale as much as `Supreme` during the winter. 
8. Lynise` has thicker leaf blades than `Supreme`.

DESCRIPTION 
(All color references are measured against The Royal Horticultural Society 
Colour Chart). 
Origin: Seedling. 
Botanic classification: Spathiphyllum hybrida `lynise`. 
Propagation: Asexual reproduction either through tissue culture or 
division. 
Plant: In a 15 gallon pot, `Lynise` will be at the mature size of 
approximately 0.7 meters to 1.0 meters in height and approximately 1.0 to 
1.4 meters in width after approximately 50 weeks to 62 weeks under the 
appropriate growing conditions from tissue culture. 
Leaves: 
Form.--The leaf blade is simple elliptic with an apice having aristate 
tendencies and a cuneate base. 
Size and width.--Leaf blades of a mature sized plant will be approximately 
35 cm to 45 cm in length and approximately 12 cm to 20 cm in width. 
Petiole.--The petiole will be approximately 32 cm to 45 cm in height from 
the soil surface to the base of the leaf blade. The petiole will be 6 mm 
to 10 mm in diameter. 
Texture.--Leaves will be less glossy than `St. Mary's` or `Supreme`. Leaves 
will be somewhat stiffer and thicker than `St. Mary's` or `Supreme`. 
Veins.--Well defined, closely spaced sunken veins giving a corragated 
appearance. Well defined veins on mature sized leaves are approximately 6 
mm to 10 mm apart and stand prominately out on the abaxial side. This 
pattern may not be evident in leaves less than the mature size. This 
veination pattern is distinct from the veination pattern of `St. Mary's`, 
but may be approximated by a few leaf sections of `Supreme`. 
Color: Mature leaf: Adaxial side 147A, 137A. Abaxial side 137B, 137C. 
Immature leaf: Adaxial side 138C, 138B. Abaxial side 147B. 
Inflorescence: 
Immature.--The spathe is tightly rolled around the spadix and extrudes from 
the petiole sheath. The spathe is fully open approximately when the 
pedicel is fully elongated approximately 0.9 meters to 1.1 meters from 
soil surface to base of spathe. 
Mature spathe: 
Size.--The spathe is approximately 20 cm to 28 cm in height and 
approximately 9.0 cm to 12.0 cm in width. 
Color.--The color is 155D turning to 138B as the spathe matures. 
Arrangement.--The spathe stands up on straight wiry pedicels and opens 
vertically above the leaves. 
Shape.--The spathe is roundish to oval with an aristate apice. It is 
slightly cupped. 
Flowering time.--After approximately 9 months to 11 months from tissue 
culture for an untreated plant and depending on season, 1 to 3 blossoms 
are present. Smaller blossoms may occur on less mature growth. 
Reproductive organs: 
Spadix.--Size: Approximately 7 cm to 10 cm in height and approximately 18 
mm to 25 mm in diameter. Color: 158C changing to 147A as the spadix 
matures. 
Stamens.--Anthers and filaments not clearly visible. 
Pollen.--158C in color. 
Pistle.--158C in color, protruding between the staminate flowers, firmly 
fixed to the main axle. The pistilate flowers extend approximately 2 mm to 
4 mm beyond the staminate flowers. 
Roots: White fleshy main roots with finer laterals. 
GENERAL OBSERVATIONS 
Spathiphyllum `Lynise` is a faster growing Spathiphyllum than cultivars 
`St. Mary's` or `Supreme` that suckers as a mature single plant and forms 
a dense mass when propagated from tissue culture clumps. It is medium 
green, about the same color as `Supreme` but darker than `St. Mary's`. It 
is about the same size but taller than `Supreme` and smaller than `St. 
Mary's`. `Lynise`, in combination with the characteristics described 
above, is a unique new cultivar.
