Abstract

In recent years many alien adventive species found their ways to Taiwan. In this report we document the naturalization of the New World Chromolaena odorata, a problematic weed, that is growing rampantly on southern part of this island. A taxonomic account, line drawing, and distribution map for Taiwan with notes on this obnoxious weed are provided.

中文摘要

原產美洲之香澤蘭(菊科)近年來大量規劃於台灣南部。香澤蘭為多年生蔓性草本，生長迅速，繁殖力強，植株並含植物相剋物質，在河谷向陽兩側、廢修耕地、崩塌地、林道邊坡、森林邊緣、牧場、火燒地區往往大量滋生，原生植被受其侵害至鉅。此外，香澤蘭之莖葉富含硝酸鹽，人畜誤食易中毒。本文提供其分類性狀描述、植物繪圖以及在台灣之分布圖。
