Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0027] The accompanying colored photographs illustrate the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.

[0028] The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘BBYEL’ grown in a container.

[0029] The photograph on the second sheet is a close-up view of a typical flower and flower buds of ‘BBYEL’.

DETAILED BOTANICAL DESCRIPTION
