23 species or less?

Hi George
Thanks very much for your valuable and sound reply This must be 
about the first I received from anyone of the Hosta society since 
my paper appeared a year ago. I agree that the number of species 
could be even lower than 23. Just as you were, I was caught 
between what was best scientifically and what was best for the 
gardening community. So in some cases I choose the latter. You 
already cleaned up a lot what was so far accepted in the gardening 
community To go even further as I did would not have been received 
favorably at that time. However science progresses and there are 
now new results based on total amount of DNA per nucleus. I could 
not escape the result and had to bring the number of species back 
to 23, about the same number as Fujita in 1976 who studied them 
extensively in the field. I suspect that any results based on DNA 
sequencing as you are planning will not bring back any of the taxa 
now rejected by me,  but might indeed lower the number even a bit 
further. To give an example: H rupifraga could turn out to be better 
placed as a subspecies of H longipes.
