应用叶表皮结构讨论槽稃草属Euthryptochloa　Cope（Gramineae）的归属问题

DISCUSSION ON THE VALIDITY OF EUTHRYPTOCHLOA COPE (GRAMINEAE) AS GENUS BY LEAF EPIDERMIS

比较研究单种属，槽稃草属ＥｕｔｈｒｙｐｔｏｃｈｌｏａＣｏｐｅ与显子草属ＰｈａｅｎｏｓｐｅｒｍａＭｕｎｒｏ的叶表皮微形态，并结合外部形态特征说明槽稃草属与显子草属无论在叶表皮微形态或外部形态上都无区别。根据国际植物命名法规的优先律，槽稃草属不能独立成属。

This paper deals with the validity of Euthryptochloa Cope by leaf epidermis. According to the characters of leaf epidermis and gross morphology, distribution, it is very similar to the Gen. Phaenosperma Munro ex Benth. According to the priority of International Code, the monotypic genus Euthryptochloa Cope should be referred to monotypic genus Phaenosperma Munro ex Benth.
