摘　　要：东方水韭(Isoetes orientalis H.Liu et Q.F.Wang)是2005年首次发现于浙江松阳的新种,已被列为我国一级重点保护野生植物.目前,在福建省泰宁峨嵋峰自然保护区发现了东方水韭的2个自然居群,共有300余株,这是在其原产地以外的地方第一次发现该种.该种的再次发现不仅增加了它的分布区范围和种群数,而且对于它的保护及其科学研究也有重要意义,同时还增补福建植物区系一新纪录科、一新纪录属和一新纪录种.Isoetes orientalis was reported as a new species from Songyang county, Zhejiang province in 2005, which is I-class national protection of wild plants. The discovery of Isoetes orientalis in Taining Emei-mountain Nature Reserve was the second time in China, the fist time in Fujian. Two natural populations of I. orientalis,a total of more than 300 strains,were found in Tainning. Meanwhile, a newly recorded family,a newly recorded genus and a newly recorded species are added to the plant flora of Fujian Province. This re- discovery not only increases the distribution and populations of I. orientalis, but also has important significance to the science study and conservation of it.
