arborescence

The term "arborescent" describes something that resembles a tree in its properties, growth, structure, or appearance. While most members of the Asparagales order are perennial herbs, some species, like certain types of Dracaena, Xanthorrhoea, and Aloe, exhibit an arborescent habit. These plants form thick stems composed of fibrous tissue, distinguishing them from true trees which have woody tissue. Some species within the Agavoideae subfamily, such as Yucca and Agave, also share this tree-like form. This growth can involve secondary thickening from a lateral cambium layer, a process that differs from the secondary growth seen in dicotyledonous trees.12
