Which inflorescence has biparous cyme ending in uniparous cymes

Options

A. cyathium
B. verticillaster
C. hypanthodium
D. strobile

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which type of inflorescence has a biparous cyme that ends in uniparous cymes. We need to identify the correct option from the given choices.

2. **Identifying the Options**: The four options provided are:
- Option 1: Seapium
- Option 2: Verticillaster
- Option 3: Hypanthodium
- Option 4: Strobile

3. **Analyzing Each Option**:
- **Option 1: Seapium**: This is a type of cymose inflorescence that typically appears as a single flower surrounded by bracts. It does not fit the description of having a biparous cyme ending in uniparous cymes.

- **Option 2: Verticillaster**: This inflorescence is characterized by clusters of sessile or subsessile flowers that are borne on a biparous cyme (dichasial) and end in uniparous cymes (monocasial). This matches the requirement of the question.

- **Option 3: Hypanthodium**: This inflorescence has a fleshy receptacle that forms a hollow cavity with flowers developing on the inner wall. It does not fit the description of biparous cymes ending in uniparous cymes.

- **Option 4: Strobile**: This is a type of spike where each flower is born in the axil of persistent bracts. It does not match the criteria given in the question.

4. **Conclusion**: After analyzing all the options, the correct answer is **Option 2: Verticillaster**, as it is the only inflorescence that has a biparous cyme ending in uniparous cymes.
