BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Gypsophila plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gypsophila plant.

(2) The photograph is composed of a side perspective view of a typical flowering stem of ESM G057 (upper left); close-up view of a typical inflorescence of ESM G057 (lower left); close-up view of a typical flower of ESM G057 (upper right); and close-up view of upper and lower surfaces of typical leaves of ESM G057 (center right).

DETAILED BOTANICAL DESCRIPTION

(3) The aforementioned photograph and following observations and measurements describe plants grown in ground beds in an outdoor nursery in El Quinche, Pichincha, Ecuador in March and under cultural practices which approximate those generally used in commercial cut Gypsophila production. During the production of the plants, day temperatures ranged from 14 C. to 21 C., night temperatures ranged from 6 C. to 9 C. and light levels averaged 19.3 klux. Plants were pinched one time three weeks after planting and were 16 weeks old when the photographs and the detailed description were taken.
