Epipetalous androecium occurs in

Options

A. Brassicaceae
B. Solanaceae
C. Asteraceae
D. Both B and C.

Answer

To determine where epipetalous androecium occurs, we will analyze the given options: Brassicaceae, Solanaceae, Asteraceae, and both B and C.

### Step 1: Understand the term "epipetalous androecium"
- The term "epipetalous" refers to stamens that are attached to the petals of a flower rather than being free or attached to the receptacle. This is an important characteristic in identifying the type of androecium in different plant families.

### Step 2: Analyze Brassicaceae
- In the Brassicaceae family, the stamens are six in number and are arranged in a tetradynamous configuration (four long and two short). However, these stamens are not epipetalous; they are attached at the base and are not connected to the petals. Therefore, Brassicaceae does not exhibit an epipetalous androecium.

### Step 3: Analyze Solanaceae
- In the Solanaceae family, the stamens are five in number and are indeed epipetalous. This means they are attached to the petals, which is a defining characteristic of this family. Therefore, Solanaceae does exhibit an epipetalous androecium.

### Step 4: Analyze Asteraceae
- In the Asteraceae family, the stamens are also five in number and are epipetalous. The filaments are free, and they alternate with the petals. This confirms that Asteraceae also has an epipetalous androecium.

### Step 5: Conclusion
- Since both Solanaceae and Asteraceae have epipetalous androecium, the correct answer to the question is option 4: both B (Solanaceae) and C (Asteraceae).

### Final Answer
The epipetalous androecium occurs in both Solanaceae and Asteraceae (Option 4).
