[Taxacom] It is possible to describe a new species?

Generically different means that the genes are different. If molecular tracking traits are the same this does not mean that the genes are necessarily the same. If two species are morphologically different this implies that they are evolutionarily different based on genetic controls, epigenetic or not or a combination, even if whatever tracking traits you are using are uninformative.

Hi Antonio,

     Even if they are genetically identical, there could well be one or more epigenetic changes (which could result in the morphological changes).  How significant are the morphological differences?

In the same locality i have trees of a species, belonging to a genre very studied, that are morphologically different. Among them a group has the pollination in January-February and the other in June-July so that crosses are exceptional. But genetically are identical, i suppose that it has not found the good marker. I have to consider them as a species or as two, which? I would describe a new one?
