Abstract

This is a report on chromosome numbers for the tribe Poeae, which is represented in South Africa mainly by naturalized
exotics. Chromosome numbers of 67 specimens, representing 26 species and 11 genera, are presented. These numbers include
the first reports on Poa binata Nees (n = 3x = 21 and n = 4x = 28), Puccinellia acroxantha C.A.Sm. & CE.Hubb. (n = 3x = 21)
and P. angusta (Nees) C.A.Sm. & C.E.Hubb. (n = x = 7). New ploidy levels are reported for Catapodium rigidum (L.) CE.Hubb.
(n = 2x = 14), Festuca caprina Nees (n = 2x = 14) and F. scabra Vahl (n = x = 7).
