琉璃草屬（紫草科）的新組合名──白花琉璃草

臺灣的琉璃草屬(Cynoglossum)（紫草科）有3個分類群：高山倒提壺(C. alpestre Ohwi)、琉璃草(C. furcatum Wall.)、小花倒提壺(C. lanceolatum Forssk.)。作者在臺灣南部中海拔林道發現花為白色之琉璃草，族群和特徵穩定。經比對特徵及標本後，鑑定其為最初由Masamune (1930)發表的Cynoglossum formosanum f. albiflorum。因此，我們為本物種提出新的組合名Cynoglossum furcatum f. albiflorum (Masam.) P.H. Chen & A.C. Chung。本文提供白花琉璃草的彩色照片以助其鑑定。

In Taiwan, the genus Cynoglossum (Boraginaceae) comprises three taxa: C. alpestre Ohwi, C. furcatum Wall., and C. lanceolatum Forssk. We identified a population of white-flowered C. furcatum with consistent characteristics along a mid-altitude forest road in southern Taiwan. After comparing characteristics of the specimens, we identified the species as C. formosanum f. albiflorum, which was first reported by Masamune (1930). Therefore, we propose a new combination, Cynoglossum furcatum f. albiflorum (Masam.) P.H. Chen & A.C. Chung. Here, color photographs of this species are provided to facilitate identification.
