臺灣產雀麥屬（禾本科）植物之數量分類學研究

A Numerical Taxonomic Study of the Genus Bromus L. (Poaceae) of Taiwan

本研究應用DELTA資料庫系統，以表徵分類之數量分類學方法檢驗臺灣產雀麥屬（Bromus L.）植物之分類。根據歸群分析的結果，我們可以確認大扁雀麥（Bromus catharticus Vahl）、臺灣雀麥（Bromus formosanus Honda）、玉山雀麥（Bromus morrisonensis Honda）及較晚發現之歸化種硬雀麥（Bromus rigidus Roth）。卑南雀麥（Bromus remotiforus（Steud.）Ohwi var. piananensis Ohwi）則併入玉山雀麥。 We conducted a numerical taxonomic study on Bromus L. in Taiwan. According to the dendrogramderived from the cluster analysis with 48 characters, 18 OTUs were divided into four groups. They areidentified as Bromus catharticus Vahl, Bromus formosanus Honda, Bromus morrisonensis Honda andBromus rigidus Roth. Furthermore, we confirmed that Bromus remotiflorus (Steud.) Ohwi var.piananensis Ohwi is a synonym of B. morrisonensis.
