Arbúsculum

Arbúsculum, also known as arbosculum or arbosculus, is a term used in botany to describe a small tree or shrub. The term is derived from the Latin words "arbor," meaning tree, and "scūlum," meaning small. In botanical literature, arbúsculum is often used to refer to small trees or shrubs that are not yet classified as full-fledged trees or shrubs, or those that do not fit neatly into either category. These plants typically have a woody stem and may bear leaves and flowers, but they are generally smaller in size compared to typical trees or shrubs. The term is not widely used in modern botanical classification, but it can be found in older texts and literature.
