Hi Mike:

I have never been able to understand LADY EMMA being called a MTB.  Other 
people say it conforms to the class, but wherever I have seen it blooming, it 
looked like an IB to me.  The blooms have been too large for MTB and the 
stems didn't have the necessary slenderness and gracefulness.

Some years ago we had some IB seedlings that approached MTB size and crossed 
them with diploid MTBs.  This did not bring the resulting seedlings down to 
the MTB requirements and they were deadends in regard to fertility.
