Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Poinsettia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia plant. The photograph comprises a side perspective view of a typical flowering plant of Dopoinatla grown in a container.

DETAILED BOTANICAL DESCRIPTION

(2) The aforementioned photograph and following observations and measurements describe plants grown in Rheinberg, Germany during the summer and autumn in a glass-covered greenhouse and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day and night temperatures averaged 18 C. and light levels averaged 4,500 lux. Single plants were grown in 13-cm containers and were pinched one time about three weeks after planting the cuttings. Plants were 23 weeks old when the photograph and the detailed description were taken. In the following description, color references are made to Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
