Rotundata

Rotundata is a Latin-derived term used in biological nomenclature as a specific epithet in the scientific names of various organisms. It is applied to species across different groups to indicate a rounded or globe-like feature, such as leaves, fruits, shells, or overall body shape.

Etymology and grammar: Rotundata is the feminine form of rotundatus (masculine) and rotundum (neuter), all meaning rounded. In Latin-based nomenclature, the epithet must agree in gender with the genus name; rotundata is used with feminine genera, while rotundatus and rotundatum are used with masculine and neuter genera, respectively.

Taxonomic usage: The epithet rotundata is descriptive rather than taxonomically definitive and may reflect a single observed trait or an historical naming convention. It occurs in botany, zoology, and, less commonly, paleontology among others. Because scientific names may reflect historical descriptions or subjective judgments, the presence of rotundata in a name does not necessarily provide a precise measurement of roundness.

See also: rotundus, rotunda, and other Latin epithets describing shape. For broader context, many languages and taxonomic traditions use similar descriptors to capture morphological traits in species names.
