Notes on grasses (Poaceae) for the flora of Taiwan (II).
Poa compressa L., P. pratensis L., and P. trivialis L. were recently naturalized in the central part of Taiwan. The existence of P. acroleuca Steud. In Taiwan was confirmed by examining the specimens deposited in HAST, NCKU, TNM, TNU, and TAI. We treated these four bluegrasses with corresponding descriptions, illustrations, and distribution maps.
