Judging classes

Classes to be judged at all shows, including monthly table shows.

at the discretion of the judges, any class with numerous entries can be split and a new sub-class created if needed.

The Society reserves the right to amend the schedule as
necessary according to any official reclassification of the genera.
That means the schedule can be revised as necessary
