C. Dioecious
D. Achlamydeous

Answer

To solve the question "A Flower without nonessential whorls is", we need to understand the structure of a flower and the terminology used to describe its parts.

### Step-by-Step Solution:

1. **Understanding Flower Structure**:
- A flower is made up of essential and non-essential whorls.
- Essential whorls are involved in reproduction, which include:
- **Androecium**: The male part of the flower, consisting of stamens.
- **Gynoecium**: The female part of the flower, consisting of carpels.
- Non-essential whorls include:
- **Calyx**: The outermost whorl, made up of sepals.
- **Corolla**: The whorl of petals.

2. **Identifying Non-Essential Whorls**:
- Non-essential whorls (calyx and corolla) serve mainly for protection and attracting pollinators, but they are not directly involved in the reproductive process.

3. **Analyzing the Options**:
- **Monoecious**: Refers to plants that have both male and female reproductive organs on the same plant.
- **Dioecious**: Refers to plants that have male and female reproductive organs on different plants.
- **Eclamydus**: Refers to flowers that lack both sepals and petals (non-essential whorls).

4. **Conclusion**:
- Since the question asks for a flower without non-essential whorls, the correct answer is **Eclamydus**. This type of flower does not have the calyx (sepals) and corolla (petals), which are the non-essential whorls.

### Final Answer:
The correct answer is **Eclamydus**.
