B. paratype
C. neotype
D. isotype

Answer

To solve the question regarding the duplicate of a holotype from the same collection, locality, date, and branch of the plant, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Holotype**: This is the single physical example (or type specimen) of an organism, which is used to formally describe and name a species. It is the most important specimen to which the name of the species is permanently attached.

2. **Identifying Duplicates**:
- When a holotype is collected, duplicates of this specimen can be made. These duplicates are essential for sharing and studying the species without damaging the original specimen.

3. **Defining Isotype**:
- A duplicate of the holotype that comes from the same collection, locality, date, and branch of the plant is specifically referred to as an **isotype**. It is important to note that isotypes are considered to be part of the same original collection and serve as additional references for the species.

4. **Distinguishing Other Terms**:
- **Syntype**: This refers to specimens cited by the author when a holotype was not designated or has been lost.
- **Paratype**: This is a specimen that helps to define the species but is not the holotype. There can be multiple paratypes.
- **Neotype**: This is a specimen selected to serve as a type when the original holotype has been lost or destroyed.

5. **Conclusion**:
- Given the definitions and distinctions, the correct answer to the question is that the duplicate of a holotype from the same collection, locality, date, and branch of the plant is called an **isotype**.

### Final Answer:
The duplicate of a holotype from the same collection, locality, date, and branch of the plant is called an **isotype**.
