摘要
密脉羽羊齿(?)[Neuropteridium? nervosum Halle]是华北区上石盒子组重要代表植物之一。自1927年赫勒[Halle]正式发表以来,它的产地虽有所增加,甚至华南的龙潭煤系也有其踪迹,所在的地质时代均属晚二叠世,说明它是一良好的标志植物化石,在地层对比方面有着一定的意义。但是,五十年以来,有关这种植物的归属问题却一直悬而未决,在“中国古生代植物”一书,仍然袭用种名创立者当初加“?”号而暂归于Neuropte-ridium属名之内。
Neuropteridium?nervosum Halle,one of the most characteristic elements of the flora of the Upper Shihhotse Formation in North China,has recently been found in the Lungtan coal-bearing formation of South China,and exhibits with certainty an age of late Permian.This species was originally described by Halle in 1927;however,its generic determination cannot definitely be made until more material is available.It has remained a dispute to be settled since half a century ago.The occurrence of a bipinnate frond in N.?nervosum Halle from the Upper Shihhatse formation has led the present author to come to the conclusion that Neuropteridium?nervosum belongs undoubtedly to the genus Pecopteris,this plant being,therefore,known as Pecopteris nervosa(Halle)Wang,nov.comb.
