| Abstract: |
A new variety of chrysanthemum plant originating as a sport of the unpatented cultivar Albatross and distinguished by its much larger flower size and more incurved form, its longer form retention, the increased diameter and length of its stems, and the larger and more luxurious appearance of its foliage. |
| Claim: |
I claim:
1. A new and distinct cultivar of chrysanthemum plant, substantially as herein shown and described, characterized by the larger size of its blooms and foliage, when compared with itsparent plant, and the greater height and size of its flowering stems. |
| Description: |
BACKGROUND OF THE NEW PLANT
My new chrysanthemum was discovered by me at East Palo Alto, Calif., as a sport of a plant of the variety Albatross being grown in my greenhouse for the commercial market. The clear white color and large size of the bloom and growth of thissport prompted me to reproduce it by means of cuttings from the flowering stem in the hope that I had found a new plant of valuable commercial merit and propagation of this plant through successive generations by vegetative cuttings, at my nursery atEast Palo Alto, Calif., has demonstrated that its distinctive features hold true from generation to generation and appear to be firmly fixed.
DESCRIPTION OF THE DRAWINGS
This new chrysanthemum variety is illustrated by the accompanying photographic drawings, one sheet of which shows, in one view, the form and coloration of a typical bloom of the new variety and in another view, a side-by-side comparison of theblossom of the new plant with the blossom of its parent, the latter being the smaller flower at the left of this view. The second sheet of the drawings shows the configuration of typical leaves of this new plant by photo-mechanical reproduction ofmachine made prints of freshly cut specimens.
DESCRIPTION OF THE NEW PLANT
The following is a detailed description of my new variety of chrysanthemum plant with color designations according to the R.H.S.
