A concentrated deposit of carbonized cereal grains was excavated at
Haimenkou site, Yunnan, in 1957. Based on its appearance the deposit
was first reported as containing barnyard millet (Echinochloa sp.) .
Sasaki (first author) received a sample from Yunnan Museum for closer
examination, using scanning electron microscopy. Matsutani identified
the cereal as foxtail millet (Setaria italica) . Here, Li discusses the
significance of foxtail millet in Chinese archaeology. Sakamoto
discusses the place of origin and possible dispersal routes of
domesticated Setaria italica. Sasaki synthesizes these discussions and
suggests the existence of a southern route among the many dispersal
routes involved in the eastward movement of domesticated foxtail millet.
