MED: TB: HIST: MTBs and Dip TBs

<<If it hadn't been for the work of Ben and others to create tetraploid MTBs, 
the class could pretty well be defined as diploid tall beards.>>

I'm concerned that some people may read this and take the concept too far in 
their minds. 

Ploidy cannot be invariably be determined by looking at the plant. There are 
some very large diploid TBs, for instance the pink pallida THAIS, or DOGROSE, 
and there are some small tetraploid TBs, such as KING TUT.  In my mind the 
classic diploid TB for comparison purposes would be QUAKER LADY.

The concept of the "Table Iris" was formed by Mrs. Peckham, editor of the 
1939 AIS Check List, on a visit to E. B. Williamson's garden. She noticed 
some intriquing dainty plants in the fields and thought something might be 
made of them. She first published the term in an article in the January, 1929 
AIS Bulletin. The type of the class is the very fine white PEWEE.
