C. Polyalthis sp.
D. Palms

Answer

**Step-by-Step Solution:**

1. **Understanding Acaulescent Habit**:
- The term "acaulescent" refers to plants that do not have a prominent above-ground stem. Instead, they may have a very short or non-existent stem, with the leaves and flowers emerging directly from the ground.

2. **Characteristics of Acaulescent Plants**:
- Acaulescent plants typically have their stem reduced to a very short length or completely absent, with the inflorescence (flowering part) being the only part that may extend above the ground.
- The main body of the plant is often below the soil surface, where it may store nutrients and energy.

3. **Examples of Acaulescent Plants**:
- Common examples of acaulescent plants include certain species of flowering plants that exhibit this growth habit. They are often found in specific environments where this adaptation is beneficial.

4. **Identifying the Correct Option**:
- The question provides four options: alien species, igneous species, polyarchaeal species, and palms. Based on the characteristics of acaulescent plants, we need to identify which of these options relates to the acaulescent habit.
- Acaulescent habit is most commonly associated with alien species, as they often exhibit this growth form.

5. **Conclusion**:
- Therefore, the correct answer to the question is option 1: alien species.
