B. Anatomical characters of new species
C. Physiological character of new species
D. Character of endosperm

Answer

To determine the characters mainly used for the declaration of new species of higher plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Higher Plants**: Higher plants, particularly angiosperms, are flowering plants that are classified based on various characteristics.

2. **Importance of Floral Characters**: The floral characters are crucial for the classification of new species. This includes the structure and arrangement of reproductive organs such as the anther (male part) and carpel (female part).

3. **Anatomical and Morphological Considerations**: While floral characters are primary, anatomical (internal structure) and morphological (external structure) characteristics are also considered later in the classification process.

4. **Physiological and Endosperm Characters**: Although physiological characters and characteristics of endosperm may provide additional information, they are not the primary criteria for declaring a new species.

5. **Conclusion**: Based on the importance of floral characters in the classification of new species of higher plants, the main character used is the floral character.

### Final Answer:
The characters mainly used for the declaration of new species of higher plants are **floral characters**.
