台灣產葡萄科新記錄－－白蘝

Ampelopsis japonica (Thunb.) Makino (Vitaceae), A New Record to the Flora of Taiwan

依據台灣植物誌的記載，台灣產之山葡萄屬有4種（含變種）。本文報導最近在台灣中部台中縣發現之本屬新紀錄種－白蘝（Ampelopsis japonica），本種之成熟葉與廣東山葡萄（Ampelopsis contoniensis）均為複葉，與台灣所產其他單葉之山葡萄屬植物有所區別；而其小葉具明顯之闊翅，與廣東山葡萄明顯可分。依據文獻，此種植物僅分布於中國大陸和其鄰近太平洋島嶼。本文對本種植物進行形態觀察，並提供彩色照片及繪圖。 This paper reports a discovery of Ampelopsis japonica (Thunb.) Makino from Central Taiwan. The species has compound leaves fairly similar to those of Ampelopsis cantoniensis (Hook. & Arn.) Planch. from Mainland China and its adjacent pacific islands. but is easily distinguishable from the latter by having winged rachis on the leaflets. This report raises a total of five species of the genus Ampelopsis of the family Vitaceae in Taiwan.
