spectabile

Spectabile is a Latin adjective widely used as a species epithet in the scientific naming of plants and animals. In taxonomy, it conveys the sense of something that is noteworthy or remarkable, typically reflecting a conspicuous feature such as striking flowers, bold morphology, or distinctive habit. As a descriptor, spectabile serves to identify a characteristic that stood out to the describer at the time the species was named.

In botanical nomenclature the epithet agrees with the gender of the genus. Therefore spectabile is used with neuter genera, while spectabilis is used with masculine or feminine genera. This grammatical adjustment helps maintain Latin agreement within the binomial name. Examples of extant uses include Dendrobium spectabile, a neuter-named orchid species; Cypripedium spectabile, another orchid with showy blossoms; and Clivia spectabilis, a showy-flowered member of the Clivia genus.

Because spectabile is a relatively common epithet, it appears across diverse genera and taxonomic groups, and the same epithet may be independently assigned to unrelated lineages. Over time, some names bearing spectabile have been revised or sunk into synonyms as taxonomic understanding advances, illustrating how nomenclature evolves with new evidence.

In summary, spectabile denotes a notable, observable trait in a species and is a reversible, gender-dependent element of Latin-based binomial nomenclature. It is not a reflection of taxonomic rank or relatedness, but rather of a perceived characteristic at the time of description.
