variegatum

Variegatum is a Latin adjective used in the scientific naming of many organisms to denote variegation, or the presence of differently colored patches or markings. The term derives from Latin variegatus, from variegare, meaning to variegate, and it appears in neuter, masculine, and feminine forms (variegatum, variegatus, variegata) to agree with the genus name. It is not a single taxon but a descriptive epithet applied across diverse groups.

In zoological and botanical nomenclature, variegatum indicates that the organism displays a variegated appearance. The epithet is common across many genera, including plants, ferns, lichens, and various invertebrates. Because it is a descriptive term rather than a taxonomic rank, it accompanies species names rather than standing alone.

In plants, variegation can be genetic, chimeric, or virus-induced and is often sought after in horticulture for ornamental varieties. Variegated leaves may exhibit white, cream, or yellow patches against green tissue, typically involving reduced or absent chlorophyll in affected areas. Variegatum forms can occur naturally or be propagated as cultivars for decorative use.

In zoology, variegatum similarly marks species with patchy or multi-colored patterns, though the epithet is less commonly used as a cultivar descriptor than in horticulture. The usage across taxa underscores a descriptive approach in taxonomy, focusing on appearance rather than implying a singular lineage.
