    Marks et al. (1993) state that sterile specimens of P. australis are sometimes misidentified as Arundo donax. The genera can be distinguished when in flower because the glumes of Phragmites are glabrous while those of Arundo are covered with soft, whitish hairs 6-8 mm long. In addition, Arundo glumes are much shorter than the lemmas in Phragmites.
    Neyraudia reynaudiana
    burma reed (English), cane grass (English), false reed (English), silk reed (English)

    FLEPPC (Undated) states that N. reynaudiana may be confused with P. australis, but P. australis' rhizomes are long, often forming leafy stolons; P. australis' leaf sheaths also do not have a hairy collar and its spikelets are without awns.
    Spartina cynosuroides


    VDCR / VNPS (Undated) states that big cordgrass (Spartina cynosuroides), a noninvasive species, is sometimes confused with P. australis. S. cynosuroides can be distinguished from P. australis by its sparse flowering structure and long narrow leaves.
