Cissus elongata Roxb. (Vitaceae), a New Addition to the Flora of Taiwan

本文報導最近在台灣中都與北部發現之粉藤屬新紀錄種——五葉粉藤（Cissus elongata），其成熟葉為五出掌狀複葉，與台灣原產其他為單葉的粉藤屬植物明顯可分。依據文獻此種植物分布於中國大陸、越南、印度、不丹及錫金等地，台灣為目前已知此物種分布的北界。本文描述此種植物的形態，並提供繪圖。

We report a species, Cissus elongata Roxb. which was collected from center and northern Taiwan. Cissus elongata is easily distinguished by the presence of five leaflets as compared to the simple leaf in the other species of Taiwan. The population from Hsinchu represents the northern distribution limit of C. elongata, which was previously known with the distributional range from Mainland China, Vietnam, India, Bhutan and Sikkim. In this report, we describe the morphology of this species. An illustration is also provided.
