新發現的台灣禾草－－布氏莠竹

Microstegium brandisii (Hook. f.) Rhind, a Newly Recorded Grass (Poaceae) to Taiwan.

調查台灣各主要標本館以了解禾本科的多樣性，發現屏東科技大學植物標本館收藏有3份採集自南台灣的特殊標本。經詳細比對後，確認是原產於緬甸及爪哇的布氏莠竹。本種與纖細莠竹相似，主要區別是本種僅具單一的總狀花序。本文增補此種為新紀錄之台灣產禾本科植物，並提供其物種描述、手繪圖，以及台灣莠竹屬之檢索表。

In examining specimens of the family Poaceae deposited in major herbaria of Taiwan for the study of its diversity, we identified three specimens deposited at herbarium of Department of Forestry, National Pingtung University of Science and Technology (PPI) as Microstegium brandisii (Hook. f.) Rhind, a species newly recorded to the flora of Taiwan. It has been known only from Myanmar and Eastern Java. M. brandistii is fairly similar in characters to M. tenue but the former is distinguishable from the latter by the inflorescence as a single raceme. This paper provides the description and line drawing of M. brandistii and a key to the species of the genus Microstegium of Taiwan for its identification.
