Trimerous flower, superior ovary and axlle placentation is characteristic of

Options

A. Liliaceae
B. Cucurbitaceae
C. Solanaceae
D. Compositae

Answer

**Step-by-Step Solution:**

1. **Understanding the Characteristics:**
- The question provides three key characteristics: trimerous flower, superior ovary, and axile placentation.
- We need to identify which plant family exhibits all these traits.

2. **Analyzing the Options:**
- The options given are:
- A) Liliaceae
- B) Cucurbitaceae
- C) Solanaceae
- D) Compositae (Asteraceae)
- We will analyze each option based on the characteristics mentioned.

3. **Evaluating Liliaceae:**
- The Liliaceae family (lily family) is known for having trimerous flowers, meaning the floral parts (sepals, petals, and stamens) are in multiples of three.
- They possess a superior ovary, which means the ovary is situated above the attachment of other floral parts.
- Liliaceae also exhibits axile placentation, where the ovules are attached to the central axis of the ovary.

4. **Evaluating Other Options:**
- **Cucurbitaceae:** Typically has flowers that are pentamerous (five parts) and does not fit the criteria.
- **Solanaceae:** Generally has flowers that are also pentamerous and does not exhibit axile placentation.
- **Compositae (Asteraceae):** Flowers are usually composite and do not fit the description of trimerous or axile placentation.

5. **Conclusion:**
- After evaluating all options, it is clear that the only family that matches all three characteristics (trimerous flower, superior ovary, and axile placentation) is **Liliaceae**.

**Final Answer:**
The correct answer is **Liliaceae**.
