Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0025] The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DHARWHITE’ grown outdoors, in a 16 cm pot. Age of the plant photographed is approximately 14 weeks from a rooted cutting.

[0026] FIG. 2 illustrates a close up of the flowers. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
