Answer

### Step-by-Step Solution:

1. **Understanding Citrus**: Citrus fruits, such as lemons, oranges, and limes, belong to the Rutaceae family. They are known for their high vitamin C content and unique fruit structure.

2. **Analyzing the Statements**: We need to evaluate the four statements provided about Citrus to identify which one is incorrect.

3. **Evaluating the First Statement**: The first statement claims that Citrus shows thorns which are leaf modifications. However, this is incorrect because the thorns in Citrus are actually stem modifications that serve as a defense mechanism.

4. **Evaluating the Second Statement**: The second statement describes the fruit of Citrus as a hesperidium. This is correct because hesperidium is a type of berry with a leathery rind and is filled with pulp, characteristic of Citrus fruits.

5. **Evaluating the Third Statement**: The third statement mentions that the morphology of the edible part includes placental hairs on the endocarp. This is also correct as these hairs support the developing seeds.

6. **Evaluating the Fourth Statement**: The fourth statement indicates that the epicarp shows volatile oil glands. This is true as well, as these glands are responsible for the characteristic scents of Citrus fruits.

7. **Conclusion**: After evaluating all four statements, it is clear that the first statement is the incorrect one regarding Citrus.

### Final Answer:
The incorrect statement regarding Citrus is: "It shows thorns which are leaf modifications."
