摘    要:简要回顾Sphenophyllum Koenig和Sphenophyllum Brongniart的研究历史,详细讨论该属命名中存在的问题。这两者是基于相同的模式(即Sphenophyllites emarginatus Brongniart,1822)建立的。根据2006年《国际植物命名法规》(维也纳法规)规则32.1,14.4和附录Ⅲ,Sphenophyllum Koenig因没有明确的发表日期(出版年),故为非法名称,应予废弃;而Sphenophyllum Brongniart因广为使用已被提议为保留名,其命名异名Sphenophyllites Brongniart,1822应被废弃。因此,正确名称应是Sphenophyllum Brongniart,1828。

关 键 词:楔叶属  楔叶纲  命名

Abstract:A study history of Sphenophyllum Koenig and Sphenophyllum Brongniart is reviewed briefly,and the generic identities are discussed in detail.According to relevant literature,Sphenophyllum Koenig and Sphenophyllum Brongniart were actually established on the basis of a same type,Sphenophyllites emarginatus Brongniart,1822.In accordance with the International Code of Botanical Nomenclature,Articles 32.1,14.4 and Appendix III(Vienna Code,see McNeill et al.,2006),Sphenophyllum Koenig is an invalid name because it has no clear date of publication and thereby should be rejected.Meanwhile,Sphenophyllum Brongniart has been proposed as a conserved name in view of the widespread use,so its nomenclatural synonym Sphenophyllites Brongniart,1822 should be rejected.Therefore,Sphenophyllum Brongniart,1828 is the correct name.
Keywords:Sphenophyllum Koenig  Sphenophyllum Brongniart  Sphenopsida  Nomenclature
