- And 25+ more species

## Usage

This dataset is designed to be used with the [Plant-mSyn web application](https://huggingface.co/spaces/yoshigold/plant-msyn).

To use programmatically:

```python
from huggingface_hub import snapshot_download

# Download the full dataset

    repo_id="yoshigold/plant-msyn-data",
    repo_type="dataset"
)
```

## File Formats
