Of the four widely known systems of classification one remains less phylogenetic and more natural, which is of

Options

A. Engler `&` Prantl
B. Benthan `&` Hooker
C. Rendle
D. Hutchinson

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which of the four widely known systems of classification is less phylogenetic and more natural. This implies that we need to identify a classification system that focuses more on natural characteristics rather than evolutionary relationships.

2. **Reviewing the Classification Systems**: The four systems mentioned in the options are:
- Angler and Prandtl
- Bentham and Hooker
- Wrangley
- Hutchinson

3. **Defining Phylogenetic Classification**: Phylogenetic classification is based on the evolutionary relationships among organisms. It uses genetic, morphological, and other data to classify organisms according to their evolutionary history.

4. **Identifying Natural Classification**: A natural classification system focuses on the observable characteristics of organisms, such as morphology, cytology, and anatomy, rather than their evolutionary lineage.

5. **Analyzing Each Option**:
- **Angler and Prandtl**: This system is more phylogenetic as it considers various groups of plants and their evolutionary relationships.
- **Bentham and Hooker**: This system is known for its natural classification approach, focusing on the characteristics of seed-bearing plants.
- **Wrangley**: Similar to Angler and Prandtl, this system also emphasizes phylogenetic relationships among flowering plants.
- **Hutchinson**: This classification system is phylogenetic as it studies flowering plants based on their morphological traits.

6. **Conclusion**: Based on the analysis, Bentham and Hooker’s system is recognized for being more natural and less phylogenetic compared to the other systems. Therefore, the correct answer is **Bentham and Hooker**.

### Final Answer:
**Bentham and Hooker**
