Just a few answers It is not very relevant to say that hosta might be 
original polyploids Nearly all genera are originally. However anyone 
who has done some controlled crosses in hosta like I did with 
white flower color and blue and yellow leaf color knows that they 
now behave as perfect diploids.The fact that not all populations are 
swamped by hybrids is simple apart from geographical separation: 
Nearly all hybrids between species have a lowered fertility. I did not 
based my conclusions on DNA content and pollen alone. I did grow 
all plants mentioned in our article for several years in the garden 
and did take all relevant morphological characters in consideration 
too. Lastly It is outright misleading to say that my data are not 
correct by starting with false suppositions like  that Hosta range 
from 28 to 32 pg (should be from 17.2 to 26.6 pg, excluding 
polyploids) and  that the figures give are  +/-  5%. Why not read 
something first before giving any comment ?.
