D. all of these

Answer

To solve the question "Floral diagram does not show", we need to analyze the options provided and understand what a floral diagram typically represents.

### Step-by-Step Solution:

1. **Understanding Floral Diagrams**:
- A floral diagram is a graphical representation of the structure of a flower. It illustrates the arrangement of various floral parts such as sepals, petals, stamens, and carpels.

2. **Analyzing the Options**:
- **Option A: Cohesion and Adhesion**:
- Floral diagrams can show the relationship between different parts of the flower, which includes aspects of cohesion (how parts stick together) and adhesion (how different parts interact). This option is likely not correct.

- **Option B: Estimation**:
- Estimation in the context of floral diagrams could refer to the relative sizes or numbers of floral parts. While floral diagrams do provide some information about the arrangement and number of parts, they may not provide precise measurements or estimations. However, this option is still somewhat ambiguous.

- **Option C: Colors and Shapes of Petals**:
- Floral diagrams do not typically depict the colors or detailed shapes of the petals. They focus more on the structural arrangement rather than aesthetic characteristics. This option seems to be the most accurate.

- **Option D: All of These**:
- Since we have identified that option C is correct, this option cannot be correct as it implies that all previous options are not shown by floral diagrams.

3. **Conclusion**:
- Based on the analysis, the floral diagram does not show the colors and shapes of petals. Therefore, the correct answer is **Option C**.

### Final Answer:
**C. Colors and shapes of petals**
