Macrophyllus

Macrophyllus is not a taxon on its own but a Latin-derived species epithet used in botanical nomenclature. The term literally means "large-leaved" and is applied to plant species whose leaves are comparatively large relative to related taxa. As a specific epithet, macrophyllus appears across many genera, reflecting a morphological characteristic rather than a shared evolutionary lineage.

Etymology and grammar: macrophyllus derives from the Greek makrós meaning large and phyllon meaning leaf. In botanical Latin, macrophyllus is the masculine form of the adjective; feminine forms include macrophylla and macrophyllum for corresponding gendered species epithets. The epithet is paired with a genus name to form a full scientific name, for example in a plant species described as Genus macrophyllus. The same epithet can be reused in different genera because it describes a trait rather than a unique taxon.

Usage and scope: Because epithets are reused across many unrelated genera, macrophyllus does not indicate relatedness among species. It is commonly found in a wide variety of plant groups, including trees, shrubs, and herbaceous species, wherever the leaves are notably large. Taxonomists select such epithets to highlight distinguishing leaf size during species description or classification.

Distinctions: macrophyllus should be distinguished from macrophylla (the feminine form) and from other similar epithets that describe leaf traits. When identifying a taxon, the full binomial and the authority are required, since the epithet alone is insufficient to determine the organism.
