摘　　要：首次报道了中国双盖蕨属一新记录种,中日双盖蕨(Diplazium×kidoi Sa.Kurata),该种是耳羽短肠蕨(D.wichurae(Mett.)Diels)和薄叶双盖蕨(D.pinfaense Ching)的杂交种。本研究详细描述了中日双盖蕨的形态特征,并比较了其与两个亲本的差别。D.×kidoi的发现对研究异域杂交物种形成和认识蕨类植物物种形成中广泛存在的杂交现象具有一定的意义。Diplazium × kidoi Sa. Kurata is a natural hybrid species between D. wichurae （Mett.） Diels and D. pinfaense Ching, which was only known in Japan. Two populations of the hybrid from China are reported for the first time in this paper, and detailed morphological comparison to its parents is also provided, The discovery of D. x kidoi in China will be helpful to understand the allopatric speciation of hybrids and cognize the common phenomenon of hybridization along with speciation of ferns.
