I only suppose, leaves are wide, flower much bigger, almost twice than normal form.

I am curious too. What could increase the size without changing the flower too much? Mike
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.

So have you done a chromosome count of the somatic cells?
Oh no...i only suppose.I have more regular hirsus from different sources.All has narrow leaves and smaller flower. It has wilde leaves and huge flower.That is why i think it may be 4N plant.

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

Leslie said that some says it is a hybrid.I don t think so, flower is just the same as a tipo form just larger.

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! ;)

I will have a tipo hirsu but album variety in flower, I will make pics for comparison ( because of size difference, of course)
