Abstract
Organisms come in various forms in nature. A circular cross section can be
found in many structures, such as the stems of many plants, however, plants with
a stem of a noncircular cross section also exist. It seems that a stem with a
quadrangular cross section has structural advantages and characteristics unlike
the circular cross section stem. The structure and mechanical characteristics of a
stem of quadrangular cross section of Perilla (beefsteak plant) are examined in
order to obtain new ideas for designing the optimum composite material. The
stem of the plant is mainly composed of the epidermis and cortex, vascular
bundle and pith. The cortex is the organization that provides the firmness of the
