Structure equivalent to perianth is

Options

A. Superior palea
B. Inferior palea
C. Glumes
D. Lodicules.

Answer

To solve the question "Structure equivalent to perianth is," we need to understand the term "perianth" and analyze the options provided.

### Step-by-Step Solution:

1. **Understanding Perianth**:
- Perianth is a botanical term that refers to the non-reproductive parts of a flower, specifically when the calyx (sepals) and corolla (petals) are not differentiated. In simpler terms, it is the collective term for both the sepals and petals when they appear similar or fused together.

2. **Analyzing the Options**:
- **Superior Palae**: These are bracts found in the spikelets of grasses. They do not relate to the structure of perianth.
- **Inferior Palae**: Similar to superior palae, these are also bracts in grass spikelets and do not correspond to perianth.
- **Glimmules**: Glumes are involucre structures in the inflorescence of a spike. They serve a different function and are not equivalent to perianth.
- **Lodicules**: These are small, scale-like structures found below the ovary in some flowering plants, particularly in grasses. They are similar in function to perianth since they help in the flower's reproductive processes and are not differentiated like calyx and corolla.

3. **Conclusion**:
- Since lodicules share a structural similarity with perianth, the correct answer to the question is **Lodicules**.

### Final Answer:
The structure equivalent to perianth is **Lodicules**.
