Answer

To determine the floral formula of the family Fabaceae, we can break down the characteristics of its flowers step by step:

### Step-by-Step Solution:

1. **Identify the Symmetry**:
- Flowers of the Fabaceae family are zygomorphic, meaning they have bilateral symmetry. This is an important feature to note.
- **Hint**: Remember that zygomorphic flowers can be divided into two equal halves only in one plane.

2. **Determine the Bisexual Nature**:
- The flowers are bisexual, meaning they contain both male (androecium) and female (gynoecium) reproductive structures.
- **Hint**: Bisexual flowers are capable of self-pollination as they have both reproductive organs.

3. **Count the Petals**:
- The corolla consists of 5 petals, which are arranged in a specific pattern. They are in a gamosapalous condition (fused petals).
- The arrangement is typically described as:
- 1 standard petal (the largest)
- 2 wing petals
- 2 keel petals (which are fused)
- **Hint**: Visualize the flower structure to remember the arrangement of petals.

4. **Analyze the Androecium**:
- The androecium consists of 10 stamens, which are arranged in a diadelphous condition. This means that 9 stamens are fused together, and 1 is separate.
- **Hint**: Diadelphous condition can be remembered as "two groups" of stamens.

5. **Examine the Gynoecium**:
- The gynoecium has a superior ovary that is monocarpillary (one carpel) and unilocular (one chamber).
- **Hint**: Superior ovary means that the ovary is positioned above the attachment of other floral parts.

6. **Construct the Floral Formula**:
- Based on the above characteristics, the floral formula for the Fabaceae family can be summarized as:
- **Floral Formula**:
- **K(5)**: Calyx with 5 sepals
- **C(5)**: Corolla with 5 petals (1 standard + 2 wings + 2 keel)
- **A(10)**: Androecium with 10 stamens (9 + 1)
- **G(1)**: Gynoecium with 1 superior ovary
- Thus, the floral formula can be represented as:
- **K5 C(1+2+2) A10 G1**

### Final Floral Formula:
- The floral formula for the family Fabaceae is: **K5 C(1+2+2) A10 G1**.
