### Step-by-Step Solution:

1. **Understanding the Question**: The question asks where we can find information on a specific taxon. A taxon is a group of one or more populations of an organism or organisms that form a unit.

2. **Analyzing the Options**:
- **Option A: Manual**: A manual typically provides information for the identification of species, but it may not offer in-depth information on a single taxon.
- **Option B: Museum**: Museums house collections of preserved plants and animals, which can provide some information, but they are not focused on a single taxon.
- **Option C: Herbarium**: A herbarium stores plant samples and is essential for biodiversity studies, but it is more of a collection than a detailed source of information about a specific taxon.
- **Option D: Monograph**: A monograph is a detailed and systematic study of a particular organism or taxonomic group. It provides comprehensive information about a specific taxon.

3. **Choosing the Correct Option**: Based on the analysis, the best option for finding detailed information on a specific taxon is **Option D: Monograph**. Monographs give a thorough examination of a particular taxon, including its classification, characteristics, and other relevant details.

### Final Answer:
