Database Update
The World Grass Species database has been updated with a number of very important changes. With this new name we hope to become a central resource for Agrostologists worldwide.New Name
The database has been christened GrassBase following the trend of a number of other web projects.New Descriptions
Just over 150 new descriptions have been incorporated into the database, including their associated nomenclature (which can be found in the updated synonymy database). This brings our total number of species with descriptions to 10,982. If you feel we are missing any data please don't hesitate to inform us. If you have an earlier version of the nomenclature database please download it again as the links will be out of date.New Search Page
We have finally updated our search page and it is now much faster. In addition you can add GrassBase to your personal Google Homepage to quickly search our data.
Generic Descriptions
We have successfully generated descriptions for all grass genera from our species descriptions using Delta's built in abilities to summarise individual taxon descriptions.New Search Page
We have finally updated the search page and this runs a lot faster. You can view a sample query for Festuca here.
