4N means that every somatic cell contains 2 pais of chromosomes. In normal case a somatic cell contains one pair of every chromosome, it called 2N.
Oh, I understand polyploids, I have numerous 4n plants and they are all a little larger and thicker, but none twice as large. What I didn't understand was the suggestion that this could be a hybrid. What could you cross with hirsutissimum that would increase the size so much, but not otherwise change the flower? Mike

I wonder what the outcome would be, if you crossed the typical variety with var. esquirolei - maybe hybrid vigour and a larger plant and flower, that was indiscernable from the the typical form (or maybe almost so)?
Istvan, we definately need that chromosome count for your beautiful flower! ;)
