Thank you Ezeiza, I am just a simple amateur, nothing scientific in my oppinions.
Beautiful pic Derrick.
There is a sentece in the study of this genus that is used frecuently: "it is the normal variability of the the species" it is not wrong, but I think it is used in cases that there are in fact two species involved. It could be the case of N. obosletus/miniatus/deficiens, I don't think so. I admire Mike, he knows better than me this species, but seening in Spain certain localities this is one of the cases that I would say "it is the normal variability of the species". As it probably has a hybrid origin, I suppose in this process of speciation, there were many lineages and tendeces to be more "elegans" or more "serotinus" (if they really were its parents) and I think there is of course another speciation way which is the Darwinian adaptation to the environment conditions. Thinking in this, it is normal such amount of forms varieties etc... maybe is not neccesary to make more diferences, because they are not forms or varieties in a particular geographic regions, it is in the same paopulation that you could see many kind of forms. Otherwise you will have hundreds of forms.
