An
arboretum (plural:
arboreta) in a narrow sense is a collection of trees only. Related collections include a fruticetum (from the
Latin frutex, meaning
shrub), and a viticetum, a collection of
vines. More commonly, today, an arboretum is a
botanical garden containing living collections of woody plants intended at least partly for scientific study. An arboretum specializing in growing
conifers is known as a
pinetum. Other specialist arboreta include
salicetums (willows),
populetums, and
quercetums (oaks).
