Abstract: The invention concerns a new and distinct variety of Dieffenbachia cv. Morlem, originating as a sport of Dieffenbachia cv. Yellow Tropic and differing therefrom by its distinctive variegation that shows an extension of the yellow macule or coloration to substantially the whole leaf blade, excluding the central main vein, and deliniated by a distinctive green colored edge that extends around the entire circumference of the leaf without significant indentations toward the middle of the limb; this pattern of variegation and the combination of the colored areas give the new variety a luminous look which is typical of the Morlem variety; otherwise the Morlem variety has the characteristics of the parental Yellow Tropic variety.
