A genus or group of tree-like plants or organisms; also used in scientific names to denote tree-dwelling or tree-like species.
From Latin arboreus (of or belonging to trees), the neuter plural form used in scientific Latin nomenclature. Scientific naming conventions often preserve Latin plural and gendered forms.
In science, species names often keep their Latin endings—like Abies (firs) or the 'arborea' part in scientific names like Rhacodactylus arboreus (an arboreal gecko). It's like a secret language scientists use to show relationships and characteristics within the naming system itself.
