Species of Lemnaceae have a high potential for fast biomass production, and this is increasingly gaining attention among researchers in basic plant sciences as well as among entrepreneurs for feed, food and energy production. Hence, the correct identification of the species being used for different duckweed research and applications is becoming indispensable. Here, we present an updated identification key based on morphological markers to the currently accepted 36 species of duckweeds, considering all taxonomic revisions since the publication of the previous key by E. Landolt in 1986. We also provide supplementary morphological characterization and the geographical occurrence of each species of Lemnaceae.

确定Lemnaceae的分类单元的关键：更新

菌科物种具有快速生产生物质的巨大潜力，这在基础植物科学的研究人员以及饲料，食品和能源生产的企业家中日益受到关注。因此，正确识别用于不同浮萍研究和应用的物种变得必不可少。在此，我们考虑到自E. Landolt于1986年发布前一个密钥以来的所有分类学修订，针对当前接受的36种浮萍提出了一种基于形态标记的更新识别密钥。我们还提供了补充的形态特征和地理上的发生葡萄科的每个物种。
