Transpiration through waxy coating over epidermal layers of leaves is known as lenticular transpiration.

Explanation

**Step-by-Step Solution:**

1. **Understanding Transpiration**: Transpiration is the process through which plants lose water vapor from their aerial parts, primarily through small openings called stomata. It is essential for maintaining the plant's water balance and facilitating nutrient uptake.

2. **Identifying the Types of Transpiration**: There are different types of transpiration:
- **Cuticular Transpiration**: This occurs through the waxy cuticle covering the epidermis of leaves. The cuticle is a protective layer that reduces water loss.
- **Lenticular Transpiration**: This type occurs through lenticels, which are small openings found in the bark of woody plants. Lenticels allow for gas exchange and some water vapor loss.
