Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

Cytogenetic studies in some representatives of the subfamily Pooideae (Poaceae) in South Africa. 2. The tribe Aveneae, subtribes Phalaridinae and Alopecurinae.

Abstract

Chromosome numbers are reported 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 (n = 4x = 28). New ploidy levels are reported for Phalaris aquatica (n = x = 7), A. barbuligera var. barbuligera (n = 2x = 14 and n = 4x = 28) and A. lachnantha var. lachnantha (n = 3x = 21).
