silk in hosta seed

Hi Charles 
all pollen grains even from a single anther are genetically different 
just as are all egg cells .What you have noted as silk ( = pistil)  is 
not that but probably the 'umbilical cord' or funiculus. Look for 
further details about the seeds of hosta in  my article about seed
