[SpaceAgeRobin] Re: HYB: Arilbred SA's

I found the picture in Garden Iris.
I couldn't find the reference re multicellur beard hairs but 
remember it was in a list of distinguishing features of various 
groupings of iris and arils and Eupogons were both listed as having 
multiceluar beard hairs.

Under the microscope the AB beard hair had many knobs, as in GI 
picture , but was multicellur the same way as bearded iris, only 
slightly narrower but same cell count in width of beard.Cell 
stucture in beards seem to be the same as flower petals.
It takes some time to prepare slides for viewing so can only find 
time to do a few every couple of days. Would like t ohave the time 
to do more. Some interesting things. Wish to have more samples 
before saying anything, but some possible explinations for a few 
genetic phenomenon can possibly be explained through cell structure 
differences.
