Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘KERPRILPRO’ grown in a greenhouse, in Cambridge, United Kingdom.

(2) FIG. 2 illustrates in full color a typical mature flower of ‘KERPRILPRO’ during Spring. Age of the plant photographed is approximately 90 days from a rooted cutting in a 20 cm basket.

(3) 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.
