摘　　要：乌蒙羊齿属Wumengopteris Tian et Zhang 1980和羽羊齿属Neuropteridium Schimper 1879是见于晚二叠世华夏植物群中的两类植物化石。乌蒙羊齿属目前仅见于国内晚二叠世华夏植物群中,羽羊齿属分布相对较广,见于亚欧大陆中二叠统至中三叠统。二者小羽片形态特征比较相似,主要差别是前者是二回羽状复叶,后者是一回羽状复叶。过去有部分被认为是羽羊齿属的标本已经被归入到了乌蒙羊齿属。根据目前已经报道的乌蒙羊齿属和羽羊齿属文献资料,本文对这两属的研究现状进行了比较和梳理。Both of the Wumengopteris Tian et Zhang 1980 and Neuropteridium Schimper 1879 are the fossil plants reported from Cathaysian Flora in the Upper Permian. But the latter was distributed from the Middle Permian to the Middle Triassic in the Eurasia continent;the former was only found in Cathaysian Flora in China. The pinnules of the two genera are very similar, but the frond of the former is bipinnate in morphology, while the latter is unipinnate. Several specimens were treated as Neuropteridium should be assigned to Wumengopteris. Based on the literature collected, the article compares the two genera as a whole.
