The floral formula of family Brassicaceae includes all, except

Options

A. `K_(2+2)`
B. `A_(2+4)`
C. `G_(1)`
D. `C_(4)`

Answer

To solve the question regarding the floral formula of the Brassicaceae family, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Brassicaceae Family**:
- The Brassicaceae family, also known as the mustard family, has a specific floral formula that we need to analyze.

2. **Identifying Floral Characteristics**:
- The floral formula of Brassicaceae is typically represented as **K4 C4 A2+4 G(2)**.
- Here, K represents the calyx, C represents the corolla, A represents the androecium (stamens), and G represents the gynoecium (carpels).

3. **Analyzing Each Component**:
- **Calyx (K)**: The calyx is usually composed of 4 sepals (K4).
- **Corolla (C)**: The corolla consists of 4 petals (C4).
- **Androecium (A)**: The androecium has 2+4 stamens (A2+4), which indicates that there are 2 short and 4 long stamens.
- **Gynoecium (G)**: The gynoecium is bicarpillary and syncarpous, meaning it has 2 fused carpels (G(2)).

4. **Identifying the Exception**:
- The question asks which component is **not** included in the floral formula of the Brassicaceae family.
- From the breakdown, we can see that the components are K4, C4, A2+4, and G(2).

5. **Conclusion**:
- The exception in the floral formula of the Brassicaceae family is related to the gynoecium. The typical structure is syncarpous with a superior ovary, but if an option suggests a different structure (like a different number of carpels or an inferior ovary), that would be the correct answer.
- Therefore, the correct answer to the question is the option that does not fit the characteristics outlined above.

### Final Answer:
The floral formula of the Brassicaceae family includes all, except the option that describes a different gynoecium structure.
