For the genus Microstegium Nees (Poaceae: Andropogoneae) of Taiwan, four known species have been verified. They are Microstegium ciliatum (Trin.) A. Camus, Microstegium fauriei (Hayata) Honda, Microstegium geniculatum (Hayata) Honda and Microstegium vimineum (Trin.) A. Camus. This paper described additional two species, Microstegium spectabile (Trin.) A. Camus and Microstegium tenue (Trin.) Hosok, as the supplements to the Microstegium flora of Taiwan. M. spectabile is a replacement of misidentified endemic species M. okamotoi Honda, while M. tenue is a new record. Also, a key to the six valid species of the genus Microstegium of Taiwan and line drawings of the two supplementary species are provided for identification.
