Afraid I certainly don't have a chromosome count. I gather their is some
controversy here but I'm not sure if you are questioning:
A. the sterility of the plant or
B. the supposition that the plant is a hybrid with the above named

If B, then is it safe to assume that sterility of hybrids is always a
result of differing ploidy?

I'm feeling a tad red faced at the moment . . .Public apology for
cluttering the listserver. The only excuse I can offer is that I have
been home a lot recently with a sick one year old and have obviously seen
a wee too much Barney and Teletubbies. . . . Time for tubby bye bye
