Neocalamites rugosus Sze和Equisetites asperrimus Franke是同物异名

NEOCALAMITES RUGOSUS SZE AND EQUISETIT ES ASPERRIMUS FRANKEARE SYNONYMUM

研究表明,斯行健(1956)建立的我国晚三叠世植物化石新种Neocalamites rugosus Sze和德国哈茨山脉考依波期的Equisetites asperrimus Franke是同物异名。Franke提定的种名有优先权,但属名鉴定有误。斯行健鉴定的属名正确,但其种名却是Franke名称的晚出异名。根据国际植物命名法规,两者应合并为一种,特定名为Neocalamites asperrimus(Franke),comb.nov.

By Literature surveying, the writer found that both Neocalamites rugostis Sze and Equise (?) as perrimus Franke are synonymum. The former was created by Sze ( 1956) for specimens of plant fossils collected from that Yenchang Formation (Upper Triassic) in the North Shensi of China, and the latter was named by Frankc (1936) for the Keuper plant fossils obtained from the Thale, Northern Harz, Mountains of Germany. The specific name used by Franke should be conserved based on the grounds of priority, but the gencric name might be transferred to the genus Neocalamites because there were no other classifiable features, such as the fertile organ, leaf-sheath and nodal diaphragm, ate known in the Harz material. The generic determination of Sze's is valid, but the specific name is a later synonymum of Franke's and is therefore illegimate. So the both can be combinaled and the writer named them here New alumites asperrimus(Franke) Shen, comb. nov.
