紅絲薑花（學名：Hedychium gardnerianum）是薑科薑花屬下的一種草本植物，原産於印度、尼泊爾、不丹及中國的西藏和雲南地區^[2]^[3]。這種植物是世界百大外來入侵種之一。

分佈

紅絲薑花是薑花屬分佈最廣泛的園藝植物，偏好熱帶氣候，但在亞熱帶及溫帶地區氣候適宜之處也可以生長。該植物在許多地區都被當做入侵物種，其中包括紐西蘭、^[4]夏威夷^[5]和亞速群島。^[6]

特徵描述

紅絲薑花的莖高度約為1-1.6米。葉為線狀橢圓形，頂端尖銳，基部楔形或近圓形，葉面為深綠色，平滑無毛，葉背淺綠色被白粉，僅中脈被長而密的柔毛，邊緣狹，軟骨質。幾乎沒有葉柄；葉鞘黃綠色或略呈紫紅色，被白粉，幼時白粉更加明顯，無毛；葉舌長圓形，頂端圓形，膜質，黃綠色或略呈紫紅色，幼時被白粉，無毛。^[2]

穗狀花序圓柱形，頂生直立，苞片非覆瓦狀，彼此分離，40-60枚在花序上螺旋狀排列。苞片內卷呈管狀，線狀披針形，綠色無毛被白粉，每苞片內有1-2朵花；小苞片管狀，黃綠色無毛。花為檸檬黃色，雄蕊紅色；花萼管狀，黃綠色，頂部略帶檸檬黃色，無毛；花冠管基部黃綠色，向上漸變為檸檬黃色至先端略呈橙紅色，無毛；花冠裂片線性，內卷，後方略長於側生裂片，檸檬黃色；側生退化雄蕊較花冠裂片為寬，線狀長圓形，檸檬黃色，基部漸呈橙紅色，先端圓鈍；唇瓣倒卵形，檸檬黃色，基部漸呈橙紅色，先端圓鈍或微凹；花絲紅色；花葯弓形彎曲；柱頭超出花葯，具緣毛；子房圓柱形；上位腺體2個，檸檬黃色。^[2]

控制

在熱帶和亞熱帶地區，紅絲薑花擴張速度極其快，其粘著性很強的種子會經由鳥類和哺乳動物傳播到別的地區。^[7]唯一的驅除辦法是完全挖掉其塊莖或使用除草劑。^[8]

藥用

醫學研究發現，紅絲薑花中的一種提取物含有細胞毒性，可以用來治療肺癌。^[9]
