Search for a plant species using either the scientific name or common name, then click "Search Database"

All the species represented on this web site can be found using this search facility. The search will include synonyms. Please enter either all or part of the species name in the relevant box. You can choose to fill in just one of the fields or both.

Searching using both fields:

If you choose the "OR" option (set as the default option) and fill in both scientific name and common name you will get results that contain either of your criteria. For example, putting "silene" in the Latin name box and "white" in the common name box will retrieve a list of all species with either "silene" in their name or "white" in their name.

If you choose the "AND" option and fill in both scientific name and common name you will get results that contain both of your criteria. For example, putting "silene" in the Latin name box and "white" in the common name box will retrieve only those species with both "silene" and "white" in their name.
