Options

A. Pinnatisect
B. Pinnatipartite
C. Pinnatifid
D. Palmatipartite

Answer

To answer the question, "When incision in a leaf is more than halfway towards the midrib it is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Leaf Incisions**:
- Leaf incisions refer to the cuts or divisions in the leaf lamina (the flat part of the leaf). These incisions can vary in depth and can result in different leaf shapes.

2. **Identifying Types of Leaf Incisions**:
- There are different terms used to describe the depth of incisions in leaves:
- **Pinnate Sect**: This occurs when the incisions almost reach the midrib but do not completely divide the leaf.
- **Pinnate Partite**: This is when the incisions are more than halfway towards the midrib, resulting in a more pronounced division of the leaf.
- **Pinnatifid**: This is when the incisions are less than halfway towards the midrib.
- **Palmatipartite**: This refers to incisions that proceed more than halfway towards the base of the leaf rather than the midrib.

3. **Determining the Correct Term**:
- Since the question specifically asks about incisions that are more than halfway towards the midrib, the correct term to use is **Pinnate Partite**.

4. **Example of Pinnate Partite**:
- An example of a plant that exhibits pinnate partite leaves is the radish. This helps to visualize the concept and understand how it applies in real-world scenarios.

### Final Answer:
When the incision in a leaf is more than halfway towards the midrib, it is called **Pinnate Partite**.
