Near Hieracium caespitosum populations on southern exposed poor grassland east of Dallau near Mosbach, which consist of many runners, there are similar populations also consisting of many runners, but with shorter stems and more laxely branched flower heads. It seems to be a stabilized hybrid population between Hieracium caespitosum and Hieracium pilosella, which is also abundant there and which forms runners, too. But due to the wider pilosella-like basic leaves it seems not to be one of the clans Hieracium prussicum, flagellare or macrostolonum, which are also standing between caespitosum and pilosella and which have been described long time ago, but which should have more longish basic leaves. The plants at Dallau however have the wider basic leaves of pilosella, from which they differ by a branched flower head on a longer stem. | ||
