Notes: This Australian species is recorded in Setshogo (2005) as being a 'naturalised or introduced plant' in Botswana but the entry is also marked as only 'possibly occurring in Botswana' suggesting there may be some doubt. It is also recorded for Botswana as a naturalised species in A checklist of Botswana grasses (Kabelo and Mafokate (2004)).
