泰国狐尾藻(小二仙草科)，中国水生植物一新记录种

Myriophyllum siamense (Haloragidaceae), A Newly Recorded Species from China

摘要:

报道了近期在我国海南岛发现的小二仙草科狐尾藻属新记录种：泰国狐尾藻[Myriophyllum siamense (Craib) Tardieu],并对该种进行了描述。该植物半水生，无羽状叶，雄花高度退化，在形态特征上同马达加斯加、澳洲和大洋洲的一些种类存在相关性，为狐尾藻属跨洲际散布提供了佐证。其发现也说明了海南岛至今还有不少植物采集的薄弱地区和盲区。

Abstract:

A newly recorded species of China, Myriophyllum siamense (Craib) Tardieu (Haloragidaceae) found in Hainan Island, China was reported and described. The species is semi-aquatic, without pinnate leaves and with highly reduced male flowers. In terms of morphological characteristics, it is related to some species in Australia and Oceania, and provides evidence for the intercontinental spread of Myriophyllum. Its discovery also shows that there are still many weak areas and blind spots in Hainan Island.
