cuneata

Cuneata is the feminine form of a Latin adjective meaning wedge-shaped or triangular. In scientific nomenclature it is most often encountered as a descriptive epithet in the binomial names of organisms, where it signals wedge-like morphology. Because Latin adjectives in taxonomic names must agree with the gender of the genus, cuneata is used with feminine nouns, while cuneatus and cuneatum appear with masculine or neuter nouns, respectively.

Usage is broad but general: many plant and animal species may bear the epithet cuneata, applied to features such as leaf shape, seed outlines, shell form, or other wedge-like attributes. The epithet does not indicate a single lineage or taxon, but rather describes a trait shared by distinct species across different groups.

In anatomy and neuroanatomy, wedge-shaped structures are described with terms such as cuneate or cuneiform; cuneata itself is not a common anatomical term but appears in taxonomic names where appropriate.

Originating from Latin cuneatus (wedge-shaped), the form cuneata is widely used in taxonomic contexts to express similarity in shape rather than relation.
