    Abstract

    Microstegium glabratum (Brongn.) A. Camus (Poaceae, Andropogoneae) is a new record for Taiwan, Japan (SW Ryukyus), and China (Hainan). Many specimens have been collected since its first discovery in 1915, but these were misidentified as M. ciliatum (Trin.) A. Camus or M. glaberrimum (Honda) Koidz. Its existence in Taiwan is confirmed by the phylogeny of ITS/5.8S sequences and its identity is figured out after examining the related specimens.

    中文摘要

    本文報導中國、日本及臺灣之一種新紀錄種禾草：光莠竹（禾本科蜀黍族）。本種最早採自1915年，而後陸續有採集紀錄，惟皆被錯誤鑑定為剛莠竹或短軸莠竹。本研究依據本屬各種類之核醣體內轉錄區格間序列之親緣分析，並配合標本館模式標本之檢閱，確認本種為臺灣之新紀錄種。
