D. The older flowers are borne at the base and the younger ones at the apex.

Answer

To solve the question regarding which statement about cymose inflorescence is incorrect, let's analyze each of the provided options step by step.

### Step 1: Understand Cymose Inflorescence
Cymose inflorescence is characterized by a specific arrangement of flowers where the main axis terminates in a flower. This leads to a pattern where the older flowers are typically found at the apex (top) and the younger flowers at the base.

### Step 2: Analyze Each Statement
1. **Statement 1**: "Members of the genus Solanum show solitary or cymose inflorescence."
- **Analysis**: This statement is correct. Plants like potato and brinjal (eggplant) from the Solanum genus do exhibit cymose inflorescence.

2. **Statement 2**: "The arrangement of flowers shows a basipetal arrangement."
- **Analysis**: This statement is also correct. In cymose inflorescence, the flowers are arranged in a basipetal manner, meaning that the older flowers are at the top and the younger ones are at the bottom.

3. **Statement 3**: "The main axis of inflorescence terminates into the flowers."
- **Analysis**: This statement is correct. In cymose inflorescence, the main axis does terminate in a flower, which is a defining characteristic.

4. **Statement 4**: "The older flowers are born at the base and the younger ones at the apex."
- **Analysis**: This statement is incorrect. In cymose inflorescence, it is actually the younger flowers that are found at the base, and the older flowers are at the apex.

### Conclusion
Based on the analysis, the incorrect statement regarding cymose inflorescence is **Statement 4**.

### Final Answer
The incorrect statement regarding cymose inflorescence is: **"The older flowers are born at the base and the younger ones at the apex."**
