Dioscorea elephantipes 8form

1. Apical Meristem Division and Movement

The tuber of the scutellaria radiata does not grow in a circular shape from a single center.
As the growth point bifurcates or shifts laterally, the initial meristem develops two expansion centers, with the space between them becoming concave.
→ This creates the basic structure, which resembles a figure-8 when viewed from above.

1. Cork Layer (Tortoiseshell Pattern) Stress Distribution Pattern

The shell of the scutellaria radiata is not simply an outer layer.
As it grows and experiences internal pressure (extension), the cork layer of the epidermis expands along a crack pattern.

These cracks are typically:
• radial, radiating from the center;
• oval, creating two stress centers;
• oval, which naturally swells at both ends, forming a two-lobed structure, or an ∞ shape.
