C. evolutionary importance is not considered
D. vegetative characters are not considered

Answer

### Step-by-Step Solution:

1. **Understanding Natural System of Classification**:
- The natural system of classification groups organisms based on their similarities and shared characteristics.
- It emphasizes the relationships among organisms, particularly focusing on their common ancestry.

2. **Identifying Drawbacks**:
- One significant drawback of the natural system of classification is that it places more emphasis on natural characteristics (like morphology) rather than on evolutionary relationships.
- This system does not adequately consider the evolutionary importance of the traits being analyzed.

3. **Evaluating Options**:
- **Option A**: "Classifies the plants in up to specified level" - This is an advantage, not a drawback.
- **Option B**: "The floral characters are given more importance" - This is also an advantage, as floral characters can aid in classification.
- **Option C**: "The evolutionary importance is not considered" - This is a valid drawback of the natural system of classification.
- **Option D**: "Vegetative characters are not considered" - This is incorrect as vegetative characters are indeed considered.

4. **Conclusion**:
- The correct answer is **Option C**: The evolutionary importance is not considered.
