摘要

山芥菜于屬(Barbarea R.Brown)約含20種植物，主要分布於歐亞兩洲，其中山芥菜(B.orthoceras Ledeb.)廣泛分布於亞洲中部、東部及北美洲。在東亞共有兩種山芥菜屬植物，山芥菜(B.orthoceras Ledeb.)及台灣山芥菜(B.taiwaniana Ohwi)，它們都產於台灣。但歷來台灣的山芥菜屬植物之分類十分混亂，主要因為許多學者并未檢視Ohwi1934年發表的Barbarea taiwaniana Ohwi及Hayata1913年發表的Cardamine arisanensis Hayata的模式標本，而導致誤判，使用了錯誤的學名。作者詳加研閱相關植物的模式標本，澄清了台灣自生山芥菜屬植物的混亂學名，對台灣產的山芥菜屬、種之分類性狀詳加描述，并提供種的簡索表，臚列異名、分布圖、及兩種植物標本的照片，以資辨識。

Barbarea R. Brown consists of about 20 species distributed mainly in Europe and Asia, with the native range of one, B. orthoceras Ledeb., extending from central and eastern Asia into North America. In eastern Asia Barbarea is represented by two native species, B. taiwaniana and B. orthoceras, both of which occur in Taiwan. The taxonomy of the Taiwanese species, however, has been the subject of continuous controversy and there are drastically conflicting views as to their limits. The principal reason behind this persistent controversy is a result of the misinterpretation of the limits of two species, one described by Hayata (1913) as Cardamine arisanensis Hayata and the other by Ohwi (1934) as Barbarea taiwaniana Ohwi, by various authors without the examination of type material. We have critically examined all types cited in this paper, and clarified the confusion in the taxonomy of Taiwanese Barbarea. A detailed description of the genus and its species in Taiwan are provided. A key to the species of Barbarea in Taiwan, synonymies, notes on their distribution with maps, and photographs of representative specimens are presented.
