Arboreus
/ar-BOR-ee-us/🏷️ Taxonomy● Basic
Also known as: arborea, arboreum
A growth habit epithet for a species that grows as a tree, or at least takes a tree's form — a woody framework and a raised crown — where its closest relatives are shrubs or soft-stemmed herbs. It differs from arborescens, "becoming tree-like", which suggests a plant heading towards that form rather than one reliably reaching it. Appears as arboreus (masculine), arborea (feminine), or arboreum (neuter).
Etymology
From Latin arboreus, "resembling a tree, of trees", from arbor, a tree.
Example
“Aeonium arboreum (tree aeonium) and Lupinus arboreus (coastal bush lupine) both build the woody, raised framework the epithet describes.”
