As additions to a previous paper by the same author (Jongepier, 1982) some new localities, mostly in the province of Zeeland, are given for Eragrostis minor Host, E. pilosa (L.)Beauv., Setaria glauca (L.) Beauv., S. verlicillata (L.) Beauv. and Sorghum halepense (L.) Pers., based on records during 1982. Eragrostis pilosa appears now to be almost as common as E. minor in this part of the Netherlands. Some remarks on Setaria italica (L.) Beauv., an alien grass that was not discussed in 1982, are added. This species was found rather often along some main roads in Zeeland in the last few years, but naturalization is not yet evident.
