Speciosa

Speciosa is a Latin adjective meaning "beautiful," "handsome," "splendid," or "showy." In biological nomenclature, speciosa is often used as a specific epithet (the second part of a binomial name) to describe a species that possesses particularly striking or attractive features. When used in a scientific name, it is always italicized. The ending of speciosa must agree in gender with the genus name to comply with the rules of botanical and zoological nomenclature. For example, if the genus name is feminine, the specific epithet will end in "-a," if it is masculine, it will end in "-us," and if it is neuter, it will end in "-um." Thus, you might find Rosa speciosa, Lilium speciosum, or Centaurea speciosus. The term suggests that the species is visually appealing or noteworthy compared to other members of its genus or related species.
