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

The plant disclosed, named `Tropic Sun` is a basal suckering sport of `Tropic Snow`, U.S. Plant Pat. No. 2,869, and is distinguished from `Tropic Snow` and other known Dieffenbachia amoena cultivars by this habit and other characteristics.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

I claim: 1. A new and distinct variety of Dieffenbachia plant, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a general similarity to the parent variety, Dieffenbachia amoena cv. Tropic Snow, but having the characteristic of producing multiple basal stems which form a clump of canes, while maintaining the upright form and height of the parent, and having a greater degree of variegated foliage coloration and slightly shorter petioles and leaves.
