摘　　要：山东蛾眉蕨(Lunathyrium shandongense J.X.Li et F.Z.Li)是1984年在《植物研究》上发表的一个新种,后收载于《山东植物志》上卷。山东蛾眉蕨与东北蛾眉蕨(Lunathyrium pycnosorum(Christ)Koidz.)相比有一些重要特征,如根状茎直立、叶片下部1对羽片的基部上侧第1小羽片格外伸长,比其他小羽片长过1倍,并羽状深裂,各小羽片间缺刻处偶有少数或无节状柔毛着生及孢子周壁表面具断续的褶皱突起等,建议《中国植物志》保留其种级地位。Lunathyrium shandongense J. X. Li et F. Z. Li, a new species, was originally published in the Bulletin of Botanical Research in 1984 and then was recorded in the Flora of Shandong volume I. Compared with Lunathyrium pycnosorum（Chirist） Koidz,it has some important characteristics such as erect rhizome, excessively long first pinnulae at the top pinna of basical leaves and twice longer than normal one, little or not grown pinnatipartite, innodular pubescence between free-section-pinnulae, inconsecutive ruga among spore perispore. We should restore its species-level position in olant taxonomv.
