Julia,
Sort of. It shows branches where each group of species diverged from the others and because they know rates for mutation they can calculate back as to how many years ago all of this happened. Really quite fascinating. The computer calculates the maximum pairings but some of the pairings to me seem a bit weird or odd because of the geographic separation of the species. Other groupings make good sense.
Here are the groups of semps:
Group A cantabricum and dolomiticum
Group B ciliosum, atlanticum, arachnoideum
Group C artvinense, davisii
Group D montanum, wulfenii, grandiflorum, pittonii
Group E species from Caucusus except those in other groups as noted
Group F ruthenicum, marmoreum, iranicum
Group G kosainii, tectorum, minutum, calcareum
It is interesting that our hybrids do come from a fairly broad spectrum of the genome types within the genus although of course most owe their background of tectorum, montanum, marmoreum, wulfenii and arachnoideum.
