Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘Graelyn’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describe the color of ‘Graelyn’.

(2) FIG. 1—Shows a side view of a six-month old plant of Sansevieria ‘Graelyn’ in a 26 cm diameter pot.

(3) FIG. 2—Shows a pot down view of a typical six-month-old plant of Sansevieria ‘Graelyn’.

(4) FIGS. 3A-3B—Shows a close-up view of the typical leaves of Sansevieria ‘Graelyn’ from a six-month old plant (upper side—A, under side—B).

DETAILED BOTANICAL DESCRIPTION

(5) The new Sansevieria ‘Graelyn’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

(6) The photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar ‘Graelyn’ as grown in open field conditions in Monterrey, San Carlos, Alajuela province, Costa Rica, which closely approximate those generally used in commercial practice. ‘Graelyn’ was grown in tropical lowlands in Costa Rica with day lengths of 12 to 13 hours and ambient temperature to 85 degrees. The level of relative humidity was 80%. No supplementary artificial light is necessary.

(7) This crop does not require constant fertilization, to increase production per area about 200 kg ha−1 N, 150 kg ha−1 of P and 100 kg-ha K are required, the production is closely related with soil conditions in which they are grown.
