In botanical nomenclature, what does the abbreviation 'var.' denote?

Explanation:
Variety in botanical nomenclature marks a natural subdivision below the species, describing a population with distinct, heritable traits that are consistently observed across many individuals and can occur in multiple locations. When you see var. in a name, it signals that this infraspecific group is recognized because of those stable differences, not because it’s a separate species. This rank sits below species but above form, and it contrasts with other infraspecific ranks. A variety is typically more conspicuous and geographically widespread than a form, yet it still interbreeds with the main species. Subspecies, by comparison, usually refers to a geographically distinct population with some genetic divergence and may intergrade with other populations where ranges meet. A form denotes a minor, often sporadic phenotypic variation that isn’t stable across a broad area. Cultivar denotes a cultivated, human-selected group maintained through propagation, typically named differently and not part of natural variation. An example would be a species name followed by var. and a second epithet to denote the specific variety, such as a plant with a stable leaf or flower trait that occurs naturally within the species range.
