1 Claim. (01. 47-61) 1 2 The present invention relates to a new and dis- Flower tinct variety of rose plant of the large-flowered polyantha class, which was discovered by me as a sport of the variety known as Demure" Plant Patent No. 1065). The new sport was discovered by me in a block of greenhouse bench plants being grown under my direction and control for cutfiower purposes on property owned and controlled by my assignee-employer.

The parent variety Demure" is characterized by its production of flowers which are Cameo Pink in general color tonality, and my attention was attracted to the new sport herein because of the fact that the flowers of the sport which occurred on one of the plants of Demure bore white flowers. Further observations, tests and asexual reproduction of the new sport showed that this white flower characteristic was fixed and comes true to form by asexual reproduction, thereby establishing that the sport was a true bud variation. In addition, I have found and established that the new sport has inherited other important characteristics from its parent variety, including the characteristics 01 prolific production of cut-flowers when grown under greenhouse conditions, long-lasting quality of the flowers which frequently will last from ten to twelve days, and exceptional hardiness when grown out-of-doors. The combination of these characteristics with the white-colored flowers of the type of the parent variety Demure definitely establishes the new sport as a new variety which is distinguished from its parent, as well as from all other varieties of its class, and makes it espe-- 'cially suitable for cut-flower production.

My new variety has been asexually reproduced in greenhouses at Newark, New York, by grafting on Manetti understocks, and also by budding in fields at both Newark, New York, and at Pleasanton, California, and all such reproductions have shown that the foregoing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows specimens ofthe flowers, stems and foliage of my new variety, with the flowers and foliage in different stages 01' development.
