To indicate the rank, the abbreviation "subvar." should be put before the infraspecific epithet or after the genus name. Variety (linguistics) is a concept that includes for instance dialects, standard language and jargon. ... This article is about the meanings of the word form connected with shape or structure. ...

The term subvariety is also used in mathematics, specifically in algebraic geometry (see algebraic variety), and universal algebra.
