Options

A. Radical
B. Cauline

D. Palmate

Answer

To answer the question "Leaves arising from stem branches are," we need to analyze the options provided: radical, colline, rammel, and palmate.

### Step-by-Step Solution:

1. **Understand the Options**:
- **Radical**: Refers to leaves that arise from an underground stem. For example, in plants like radish, leaves emerge from a rhizome, which is a type of underground stem.
- **Colline**: This term is associated with leaves that arise from the main stem or the nodes of the stem. This is not what we are looking for in this question.
- **Rammel**: This term refers to leaves that arise from lateral stem branches. This is the option that aligns with the question, as it specifically mentions leaves coming from branches of the stem.
- **Palmate**: This term describes a leaf structure where multiple leaflets arise from a single point, which is unrelated to the origin of leaves from the stem.

2. **Evaluate Each Option**:
- **Radical**: Incorrect, as these leaves arise from underground stems, not from branches.
- **Colline**: Incorrect, as these leaves arise from the main stem or nodes, not specifically from branches.
- **Rammel**: Correct, as these leaves arise from lateral branches of the stem.
- **Palmate**: Incorrect, as it refers to the structure of leaves, not their origin.

3. **Conclusion**:
Based on the analysis, the correct answer to the question is **Rammel**, as it specifically refers to leaves that arise from lateral stem branches.

### Final Answer:
Leaves arising from stem branches are **Rammel**.
