Information about any one taxon of plants or animals can be found in

Options

A. Museum
B. Herbarium
C. Monograph
D. Flora

Answer

To answer the question about where information on any one taxon of plants or animals can be found, we will analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Options**:
- The question provides four options: museum, herbarium, monograph, and flora. We need to evaluate each option to determine which one provides information about a single taxon.

2. **Evaluating the Museum**:
- A museum is a facility that houses preserved collections of various biological specimens, including plants, animals, and fossils. However, it does not focus specifically on one taxon. Therefore, while museums contain valuable information, they do not specialize in information about a single taxon.

3. **Evaluating the Herbarium**:
- A herbarium is a collection of preserved plant specimens, typically dried and mounted on sheets. While it is a valuable resource for studying plants, it primarily focuses on a collection of various species rather than providing detailed information about a single taxon. Hence, this option is also not the best choice.

4. **Evaluating the Monograph**:
- A monograph is a detailed written study focused on a specific taxon of plants or animals. It provides comprehensive information about that particular taxon, including its characteristics, classification, and other relevant data. This makes the monograph the most suitable option for finding information about one specific taxon.

5. **Evaluating the Flora**:
- Flora refers to the collective plant life in a particular region or environment. It typically includes descriptions of multiple species and does not focus on a single taxon. Therefore, this option is also not correct.

### Conclusion:
Based on the evaluations, the correct answer to the question is **monograph**, as it provides detailed information about any one taxon of plants or animals.
