C. Flora, Manual, Monograph
D. Botanical Garden, Museum, Monographs

Answer

To solve the question "In which group of taxonomic aids only the means of recording descriptions are included?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomic Aids**: Taxonomic aids are tools that help in the identification, classification, and study of organisms. They include various resources like flora, manuals, monographs, herbariums, botanical gardens, and museums.

2. **Identify the Options**: The question implies there are multiple groups of taxonomic aids. We need to focus on those that primarily deal with written descriptions rather than physical specimens.

3. **Examine Each Group**:
- **Flora**: Contains descriptions of plants, their habitats, and distributions. It includes written accounts but also involves information about actual specimens.
- **Manuals**: Provide information about the names of species found in a particular area. They are primarily descriptive but may also include some physical references.
- **Monographs**: Focus on a single taxon and provide detailed descriptions. They are primarily written documents.
- **Herbariums**: Collections of dried plant specimens. They are not just descriptions but actual specimens.
- **Botanical Gardens**: Live specimens of plants are present, so they do not fit the criteria of only written descriptions.
- **Museums**: Similar to botanical gardens, they contain specimens and not just descriptions.

4. **Determine the Correct Answer**: Among the options, flora, manuals, and monographs all contain written descriptions, but the question specifies "only" means of recording descriptions. The group that fits this criterion best is **monographs**, as they focus solely on detailed descriptions of a single taxon without including specimens.

5. **Final Answer**: Therefore, the correct answer is **monographs**.
