This is a short review of the state of the art concerning diversity of aquatic macrophytes and the main aquatic vegetation types in the Brazilian Pantanal wetland and upper watershed. There are ca. 280 species of aquatic macrophytes on the Pantanal floodplain, with scarce endemism. On the upper watershed, Cerrado wetlands (veredas) and limestone springs have a distinct flora from the Pantanal, with twice the species richness. As a representative case of aquatic habitats influenced by river flood, some primary data are presented for the Pantanal Matogrossense National Park and associated Acurizal Preserve, analysing the floristic similarity among aquatic vegetation types. We comment on problems of conservation and observe that Panicum elephantipes Nees is one of the few natives to compete with the invasive Urochloa arrecta (Hack. ex T. Durand & Schinz) Morrone & Zuloaga.
这是一篇关于巴西潘塔纳尔湿地及其上游流域水生大型植物多样性和主要水生植被类型的最新研究综述。潘塔纳尔河漫滩约有280种水生大型植物，特有种稀少。在上游流域，塞拉多湿地（veredas）和石灰岩泉拥有与潘塔纳尔不同的植物区系，物种丰富度是其两倍。作为受河流洪水影响的水生栖息地的一个典型案例，本文给出了潘塔纳尔马托格罗索国家公园及相关的阿库里扎尔保护区的一些原始数据，分析了水生植被类型之间的植物区系相似性。我们对保护问题进行了评论，并指出象草是少数能与入侵的直立臂形草竞争的本土植物之一。
