Puccinellia (Poaceae) in Western Australia. Nuytsia 16(2): 435–467 (2007). Two new native species, Puccinellia longior and P. vassica, have been identifi ed from Western Australia. P. longior is restricted to the outer edges of salt lakes and salt-affected pasture land along the lower western margin of the southwest wheatbelt region in WA, and has also been collected from a saline wetland reserve in southeast South Australia. P. vassica is endemic to the outer edges of marine saltmarsh in reserved areas of the Leschenault Inlet near Bunbury. It was previously known from the nearby Vasse-Wonnerup saltmarsh near Busselton but is now extinct there because engineering works have reduced the marine infl uence in the estuary.
