Answer

To solve the question, we need to analyze each of the matches provided and determine if they are correct based on the known characteristics of the plants mentioned.

### Step-by-Step Solution:

1. **Match (i): Alstonia - Whorled phyllotaxy**
- Alstonia is known to exhibit whorled phyllotaxy, where leaves are arranged in a whorl around the stem.
- **Conclusion**: This match is **correct**.

2. **Match (ii): Calotropis - Opposite and decussate phyllotaxy**
- Calotropis indeed has opposite and decussate phyllotaxy, where pairs of leaves are arranged opposite to each other at each node, and successive pairs are rotated.
- **Conclusion**: This match is **correct**.

3. **Match (iii): Smilax - Parallel venation**
- Smilax is a plant that exhibits parallel venation in its leaves, where the veins run parallel to each other.
- **Conclusion**: This match is **correct**.

4. **Match (iv): China rose - Opposite and superposed phyllotaxy**
- China rose (Hibiscus rosa-sinensis) actually exhibits alternate phyllotaxy, not opposite and superposed.
- **Conclusion**: This match is **incorrect**.

5. **Match (v): Sunflower - Spiral phyllotaxy**
- Sunflower has spiral phyllotaxy, where the arrangement of leaves follows a spiral pattern around the stem.
- **Conclusion**: This match is **correct**.

### Final Summary of Correct Matches:
- Correct Matches: (i), (ii), (iii), (v)
- Incorrect Match: (iv)
