GrassBase - The Online World Grass Flora

Specifications

In order to use the advanced aspects of the database, you should be running Windows 95/NT or better and have INTKEY 5 installed. The latter can be downloaded from the DELTA website, where you will also find more information about DELTA and how to install INTKEY.

The INTKEY datafiles for interactive interrogation of the World Grass Species – Descriptions Database can then be launched from your browser (compressed size approximately 1.8 MB).

The written descriptions are generated from a different set of files, which run with the DELTA program CONFOR. Taxonomic or geographical subsets of these files can be supplied on application.

A set of Visual Basic utility programs (GrassUtils) have been developed at the Royal Botanic Gardens, Kew for handling large DELTA–format datasets, and these are available from here. Modules include the following:

• NAMES — lists taxon names from an ITEMS file;

• PICK — selects a subset from an ITEMS file;

• MIX — merges two ITEMS files.
