Dear All; Mary Sue posed a question regarding fragrance in some plants in the same species having fragrance and others of the same species not having any fragrance. I do not think this has anything to do with pollinators, rather geographic variation. I remember discussing this with Professor Doorenbos in Wagening, The Netherlands, back in 1956, when I was living and studying in The Netherlands. He told me that Cyclamen hederifolium from North Africa had a distinct fragrance, while others from other regions of the Mediterranean did not. His opinion was that the gene carrying the fragrance character was present in all of the species but recessive. The colonies in North Africa were of the type that allowed the gene to surface and were thus fragrant. No doubt other colonies with fragrant flowers were to be found in isolated pockets within the natural range of the plants, but all from North Africa were fragrant. This seems to me to be a logical reason. If it were due to pollinators the variations and ability to adapt to a particular habitat would mean that even greater variances in fragrance would be apparent. Cheers, John E. Bryan
