No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A new and distinct variety of white Flowering Dogwood, botanically known as Cornus florida is provided. The new variety most nearly resembles the native Flowering Dogwood, but primarily is distinguished therefrom by a compact and upright growth habit, stocky trunk and strong stubby limbs of relatively large diameter, and the abundant formation of attractive white blossoms which often are present in closely disposed clusters. The new variety was named in honor of the World Energy Fair to be held at Knoxville, Tenn. during 1982.
