Here I reported three new-naturalized grasses to the flora of Taiwan: Megathyrsus infestus (Andersson) B.K.Simon & S.W.L.Jacobs, M. maximus (Jacq.) B.K. Simon & S.W.L. Jacobs var. pubiglumis (K. Schum.) B.K. Simon & S.W.L. Jacobs and Zuloagaea plena (Hitchc. & Chase) M.J. Jung, comb. nov., and offered color photos and line-drawings of these grasses benefit for identification. New combination of Zuloagaea plena (Hitchc. & Chase) M.J. Jung is suggested, too. In addition, I confirmed the naturalized grass to southern Taiwan, which was misapplied as Urochloa deflexa (Schumach.) H. Scholz, should be Steinchisma laxum (Sw.) Zuloaga.
作者報導3種臺灣新歸化外來種禾草:柔毛大黍(Megathyrsus infestus (Andersson) B.K.Simon & S.W.L.Jacobs)、毛大黍(M. maximus (Jacq.) B.K. Simon & S.W.L. Jacobs var. pubiglumis(K. Schum.)B.K. Simon & S.W.L. Jacobs) 及巨黍 (Zuloagaea plena (Hitchc. & Chase) M.J. Jung, comb. nov.),並且提供這些新歸化禾草的彩色照片和線描圖以供辨識。巨黍的新組合名在本文中一併提出。此外,作者確認歸化於南臺灣的彎柄尾稃草(Urochloa deflexa (Schumach.) H. Scholz)應為展序黍(Steinchisma laxum (Sw.) Zuloaga)的鑑定錯誤。
