台灣產旋花科菟絲子屬（Cuscuta L.）植物之分類訂正

Cuscuta L. (Convolvulaceae) in Taiwan

本文訂正台灣產旋花科（Convolvulaceae）菟絲子屬（Cuscuta L.）植物。依據野外調查採集及歷年來的文獻與蠟葉標本，認定有3種及2變種，包括菟絲子（C. australis R. Br.）、平原菟絲子（C. campestris Yuncker）、中國菟絲子（C. chinensis Lam.）、台灣菟絲子（C. japonica Choisy var. formosana (Hay.) Yuncker）及日本菟絲子（C. japonica Choisy var. japonica）。本文確認中國菟絲子之存在；首次記錄平原菟絲子。另外，對各物種之形態及分佈加以描述，並以繁殖器官之特徵作一檢索表。

The genus Cuscuta (Convolvulaceae) in Taiwan is revised according to the results of the field investigations and examination of specimens at major herbaria. We recognize three species and two varieties of Cuscuta in Taiwan including C. australis. C. campestris, C. chinensis, C. japonica var. formosana and C. japonica var. japonica, in which, Cuscuta chinensis, a species neglected or unknown by many Taiwan authors, is introduced in detail. Cuscuta campestris, although collected as early as in 1964, is a new record. A key to the species and varieties of Cuscuta in Taiwan is provided based on the characteristics of reproductive organs, and maps of the presently known distribution of C. campestris and C. japonica var. formosana are also given.
