Abstract

There are two taxa related to Ozalis acetocella in Taiwan, which are treated as O. acetocella ssp. Taemoni and O. acetocella ssp. Griffithii var. formosana separately. The former is characterized by the ldaflets having round lobes and the length being longer than the width; the latter is distinctive by leaflets having obtuse lobes and the length being shorter than the width and the size of leaflets is smaller when compared to O.acetocella ssp. Griffithii var. griffithii. The diameter of rhizome of these two taxa are intermediate between O. acetocella and O. griffithii when compared with specimens collected from Europe, Japan and China.

中文摘要

台灣有二種白花酢醬草之近源種，台灣山酢醬草及大壩尖山酢醬草。後者分佈於台灣北部高海拔山區，小葉倒卵形，且列片圓形；前者分佈於台灣中海拔山區，小葉倒三角形，且裂片鈍狀。此二者之地下莖直徑介於白花酢醬草及山酢醬草之間。由於大壩尖山酢醬草小葉枝葉長大於葉寬，在相關種類裡是特殊一群，因此處理為白花酢醬草的亞種。而台灣山酢醬草之小葉長度，整體而言較之山酢醬草來的短，因此處理為山酢醬草之變種。
