Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying colored photographs illustrate the overall appearance of the new Isotoma 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 colors of the new Isotoma plant.

(2) The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of typical flowering plants of Isopapi grown in an outdoor nursery.

(3) The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of Isopapi.

DETAILED BOTANICAL DESCRIPTION

(4) Plants used for the aforementioned photographs and the following observations, measurements and values were grown during the summer and autumn in 19-cm containers in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial Isotoma production. During the production of the plants, day temperatures were at a minimum of 20 C., night temperatures were at a minimum of 16 C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were pinched one time two weeks after planting rooted young plants. Plants were six months old when the description was taken and seven months old when the photographs were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
