We have found some carbonized remains of grasses, which resemble Setaria and Echinochloa. Here we have in our reference collection only Panicum miliaceum, so I cannot compare these seeds with Setaria or Echinochloa species.
In the attached files there are five remains from an Pre-Roman Iron Age site in Scania, southern Sweden and on the other file one remain from a earlier remain, from a Bronze Age site also in Scania. Below are measurements of the remains.
I would appreciate suggestions on the identification of these remains and if someone knows where to get hold of reference seeds of Echinochloa and Setaria.
