Alexanderi

Alexanderi is a commonly used species epithet in biological taxonomy. It is formed as a Latinized genitive and is used in the binomial names of many organisms to honor a person named Alexander. The epithet itself does not designate a taxon; rather, it appears as the second part of a species name (the first part being the genus).

Etymology and form: The ending alexanderi signals a masculine honoree and follows standard practices for eponymous epithets in botanical and zoological nomenclature. While alexanderi is a frequent form, other epithets honoring individuals with the name Alexander may use related endings such as alexandri or alexandrei, depending on historical usage and linguistic conventions. The key idea across forms is that the epithet marks the species as named in honor of Alexander.

Usage across taxa: The epithet alexanderi appears across diverse groups, including animals, plants, fungi, and microorganisms. Because it is an epithet rather than a taxon, many unrelated genera may have a species named alexanderi. The selection of this epithet reflects the practice in taxonomy of recognizing contributors, collectors, or notable individuals by attaching their name to a species.

Notes: As with all taxonomic names, the exact spelling and suffix may be dictated by historical authorship and the rules of nomenclature governing the organism’s group. For readers seeking a specific species named alexanderi, consulting a current taxonomic database or the primary literature for the genus in question is recommended.
