Dear all,
I looked into my old kartothek:
The only Roman reference of cf. Sinapis alba is
K.-H. Knoerzer, Roemerzeitliche Pflanzenreste aus einem Brunnen bei Butzbach in
Hessen. Saalburg-Jahrbuch 30, 1973, 71-114.
Brassica/Sinapis and similar genera are very difficult to determine; best conditions and
many findings are necessary to give a decent determination.
Nearly all "Sinapis" I have seen was Brassica nigra!
[I - personly - believe that Sinapis alba comes in the Middle Ages to Central Europe]
