Abstract

This is a report on chromosome numbers for the subtribes Phalaridinae and Alopecurinae (tribe Aveneae) which are. to a large extent, naturalized in South Africa. Chromosome numbers of 34 specimens, representing nine species and four genera, are presented. These numbers include the first report on Agrostis avenacea Gmel. (n = 4x = 28). New ploidv levels are reported for Phalaris aquatica L. (n = x = 7), Agrostis barbuligera Stapf var. barbuligera (n = 2x = 14 and n = 4x = 28) and A.  lachnantha Nees var.  lachnantha (n = 3x = 21).
