Answer

To solve the question "Choose the correct statement," we need to analyze the provided statements about phylloclades and phyllodes. Let's break down the information step by step.

### Step 1: Understand Phylloclade
- **Definition**: A phylloclade is a modified stem that takes on a flattened or cylindrical form.
- **Characteristics**:
- It is succulent and green.
- It arises in the axil of the leaf, which falls off, leaving a scar.
- It has a succession of nodes and internodes at varying intervals.

### Step 2: Understand Phyllode

- **Characteristics**:
- It is leaf-like in appearance and may have a green surface.
- It bears an axillary bud.
- It does not bear flowers or buds.

### Step 3: Analyze the Statements
Now, let's evaluate the statements given in the question:

1. **Statement 1**: "Phylloclade is a stem and phyllod is a petiole."
- This statement is **true**. Phylloclade is indeed a stem modification, and phyllode is a modified petiole.

2. **Statement 2**: "Phyllod has nodes and internodes and bare flowers."
- This statement is **false**. Phyllodes do not have nodes and internodes like phylloclades do, and they do not bear flowers.

3. **Statement 3**: "Phylloclade bears bud in its axil."
- This statement is **false**. Phylloclades do not bear buds in their axils; instead, phyllodes do.

4. **Statement 4**: "Phyllod is never vertical in position."
- This statement is **false**. Phyllodes can be positioned vertically.

### Conclusion
Based on the analysis, the correct statement is:
- **Statement 1**: "Phylloclade is a stem and phyllod is a petiole."

### Final Answer
The correct answer is **Statement 1**.
