Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0036] 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.

[0037] The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of Inmanbewhi22 grown in a container.

[0038] The photograph on the second sheet (FIG. 2) is a close-up view of typical flowers of Inmanbewhi22.

DETAILED BOTANICAL DESCRIPTION
