*GipP, *VVP. Apparently rare in Victoria, the few collections (Avalon near Geelong, Coode Is near the mouth of the Yarra River) suggesting a preference for slightly saline situations, but also collected from a local park in Brighton, where growing in occasionally-mown lawn. Native to Argentina. Also naturalised NSW, Tas.
Of the 3 varieties of B. catharticus, this is the smallest in stature and in spikelet length. It has relatively broader spikelets than the other varieties and consistently pilose leaves.
