Answer

To determine how many of the listed plants belong to the Kingdom Pteridophyta, we need to classify each one:

1. **Psilotum**: This is a genus of plants that belongs to the Pteridophyta. It is a type of whisk fern.

2. **Selaginella**: This plant is also a member of the Pteridophyta. It is known as a spike moss and is heterosporous.

- **Not Pteridophyta**: Pinus, Funaria, Sphagnum, Cycas (4 plants)

Thus, the total number of plants from the list that belong to the Kingdom Pteridophyta is **5**.
