摘要
红花莼菜生殖器官的外部形态和内部的解剖结构研究结果表明：两性花，花被片６枚；雄蕊１７～２７枚，没有腺毛；心皮６～１１枚，离生单雌蕊，上位子房，其柱头、花柱、子房密生腺毛；边缘胎座，胎座柱状，与珠柄垂直接合，接合处关节明显，下垂式弯生胚珠１～３枚．通过对红花莼菜生殖器官形态和解剖结构的分析，支持莼菜属从睡莲科划分出来。
Morphology and structure of reproductive organs of Brasenia schreberi Gmel were observed and anatomized.The results were as follows:bisexual flower,tepal 6,stamen 17～27 ,no glandular hairs;carpel 6～11,separation,superior ovary;densely coveres glandular hairs on stigma,style,ovary,marginal placentation,columnar placenta and funiculus vertical joint,joit is quite clear,campylotropous ovules 1～3,hang down. Its microstructures were analysed,the results have proved this classified point that Brasenia parted from Nymphaceae and setted up Cabombaceae.
