Alpinum

Alpinum is a Latin adjective used in scientific nomenclature as a species epithet. In botany and zoology, alpinum typically denotes alpine habitat or origin, often referring to organisms from high mountain regions such as the Alps. The epithet signals a descriptive attribute rather than a taxonomic relationship.

Etymology and grammar: alpinum derives from the Latin alpinus, with masculine, feminine, and neuter forms alpinus, alpina, and alpinum respectively. When used in a binomial name, the ending of the epithet agrees with the gender of the genus name. Thus alpinum is the neuter form and appears with neuter-gender genera or in Latinized usage where a neuter form is appropriate.

Usage: The epithet is widely employed across a variety of taxa to indicate alpine distribution or origin. Its use is descriptive rather than taxonomic, and it reflects the long-standing tradition of Latin naming in Linnaean taxonomy. While most common in plants, similar alpine epithets appear in other groups as well.

Relation to other forms: Alpinum is part of a set of related epithets that express habitat or regional origin, alongside forms such as alpina (feminine) and alpinus (masculine). The choice among these forms depends on the gender of the generic name in the scientific binomial.
