Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates a plant of ‘SMNBDO’ grown in a nursery, in a 2 gallon pot.

(2) FIG. 2 illustrates in full color a typical inflorescence of ‘SMNBDO’. Age of the plant photographed is approximately 2-3 years old from a rooted cutting.

(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.
