Answer

To solve the question of selecting the incorrect statement from the given options, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Understanding Monoecious Plants**:
- The first statement claims that in some flowering plants, both male and female flowers may be present on the same individual, which is referred to as monoecious.
- This statement is **correct**. Examples of monoecious plants include maize and castor.

**Hint**: Remember that monoecious means "one house," indicating that both male and female reproductive structures are found on the same plant.

2. **Examples of Monoecious Plants**:
- The second statement mentions that monoecious plants include Cucurbita (like squash) and coconuts.
- This statement is also **correct**. Both Cucurbita and coconuts are indeed monoecious.

**Hint**: Look for plants that have both male and female flowers on the same plant to identify monoecious examples.

3. **Understanding Dioecious Plants**:
- The third statement states that dioecious plants include papaya and date plants.
- This statement is **correct**. Dioecious plants have male and female flowers on separate individuals.

**Hint**: Dioecious means "two houses," indicating that male and female reproductive structures are on different plants.

4. **Homothalism in Fungi**:
- The fourth statement claims that in saprophytic fungi and plants, homothalic and monoecious are used to denote unisexual conditions.
- This statement is **incorrect**. In fungi, the term "homothallic" actually refers to a bisexual condition, where both male and female reproductive structures are present in the same organism.

**Hint**: Remember that in fungi, homothallic means the ability to self-fertilize, which implies the presence of both sexual structures.

### Conclusion:
The incorrect statement among the options provided is the fourth statement regarding homothalism in fungi.

### Final Answer:
**The incorrect statement is option 4.**
