• The characters available relate to habit, bark, leaf, fruit, seedling, flower, family and geographic area, via the pull-down menus. 

• Each character type has its own window, and as many character types (& therefore windows) as required may be open at any one time. 

• The character windows contain the features that are available for use in the identification. Identification proceeds with the user selecting features from the window that can be seen on the specimen to be identified. 

• The features are selected by clicking on the appropriate line in the character window. At any time, it is possible to remove a selected feature, by again clicking on it. 

• A status bar at the bottom of the screen provides information on the current operation, and on the number of taxa remaining. A species window may be opened to list the taxa remaining. 

• Selecting any one of these taxa from the species window allows access to additional information on that species : 
- speciesa description & additional diagnostic features 
- an on screen distribution map 
- an x-ray image of a leaf 
- in many cases, one or more photographs of the species

• On screen help is available on all characters, with images where necessary.
