| Abstract: |

| Claim: |
It is claimed:
1. A new and distinct Begonia plant named `BCT9801BEG` as illustrated and described. |
| Description: |
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Begonia, botanically known as Begonia rex hybrid, commercially known as Rex Begonia, and hereinafter referred to by the name `BCT9801BEG`.
The new Begonia originated from a cross made by the Inventor of two unidentified selections of Rex Begonia. The cultivar BCT9801BEG was discovered and selected by the Inventor as a single plant within the progeny of the stated cross in acontrolled environment in Voorhout, The Netherlands in 1997. The selection of this plant was based on its unique leaf shape, coloration and pattern.
Asexual reproduction of the new Begonia by cuttings taken in a controlled environment in Voorhout, The Netherlands, has shown that the unique features of this new Begonia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Begonia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, nutritional and water status without, however, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `BCT9801BEG`. These characteristics in combination distinguish `BCT9801BEG` as a new and distinct cultivar:
1. Compact, uniform and outwardly spreading plant habit.
2. Freely basal branching with numerous leaves per plant, dense and bushy growth habit.
3. Spiraled silvery gray and dark green leaves.
4. Rounded leaf shape.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Begonia. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph maydiffer slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Begonia. The photograph comprises a top perspective view of a typical plant of `BCT9801BEG`.
DETAILED BOTANICALDESCRIPTION
The aforementioned and following observations, measurements and values describe plants grown in a glass-covered greenhouse in Voorhout, The Netherlands, during the winter under conditions which approximate commercial production practices. Afterthe cuttings were rooted, plants were planted in 17-cm containers and grown for about four months with day temperatures about 19 to 21.degree. C. and night temperatures about 17.degree. C. In the following description, color references are made to TheRoyal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
