Finding Hidden Outliers to Promote the Consistency of Key Morphological Traits and Phylogeny in Dennstaedtiaceae

With the development of open science and technological innovation, using sharing data molecular biology techniques in study taxonomy systematics have become a crucial component plants, which undoubtedly helps us discover more hidden outliers or deal with difficult taxa. In this paper, we take Dennstaedtia smithii as an example, based on database, virtual herbarium plant photo bank, to clarify that been find key morphological traits consistent systematics. phylogenetic analyses, used rbcL, rps4, psbA-trnH trnL-F sequences from 5 new 49 shared data; results showed is nested within Microlepia rather than Dennstaedtia. We further studied characters phylogeny result found D. distinguished other species by spore ornamentation unconnected grooves between rachis pinna rachis. According studies, our supported should be member renamed (Hook.) Y.H. Yan. Finding can promote consistency results, make systematic classification natural.
