These files are recent additions to the sample data. They're in the 
current release of the CSIRO programs, and are also available at

Keep in mind that a diagnostic description generated on demand in Intkey 
is more flexible than a printed diagnostic description, because it can 
select characters from any subset, e.g. vegetative characters. By default, 
it uses the 'Available' characters. Thus, if you use it after completing a 
(tentative) identification, it won't include characters that you've 
already used.

For confirming an identification, it's even better to increase the error 
tolerance (choose 'Settings > Set > Tolerance') and just continue with the 
identification, because then you can choose which characters to use.
