What term is associated with something that is of or pertaining to trees?

The term that refers to something pertaining to trees is "arboreal." This term is derived from the Latin word "arbor," meaning tree. In various contexts, "arboreal" can describe species that inhabit trees, characteristics of trees, or even things that have tree-like features. Understanding this term is crucial in disciplines such as ecology, forestry, and biology, where the focus is on the impact and characteristics of trees in their environments.

On the other hand, "botanical" pertains to plants in general, "dendritic" relates to tree-like structures but is often used more in the context of branching patterns rather than trees specifically, and "floral" relates to flowers. While these terms are related to plants and their structures, none exclusively define characteristics of trees like "arboreal" does.
