To make the plot thicker. I measured one triploid of S lutea wild collected in Paxos. The other I got from L de Jager. So they are both in nature and culture. I also measured S lutea Angustifolia. They were obtained from R Leeds UK and L de Jager France. Both are diploids! By the way the only S clusiana I measured came from J Grisham UK. So I repeat my question if you have any spare leaves....
