An infrageneric taxonomic revision of the genus Osmanthus
摘要
Abstract
[Objective]The genus Osmanthus Lour.species represented by sweet osmanthus has high economic and research values.However,species relationships within the genus have been controversial due to the lack of distinct morphological characters among species,and there is an urgent need for a taxonomic revision of the sectional relationships within the genus.[Method]This study integrates multiple lines of evidence from morphological characters and molecular phylogeny to define section-level taxonomic units within the genus.Taxonomic treatments were provided based on taxonomic principles and nomenclatural codes.[Result]Here we propose to divide the genus Osmanthus into four sections,first retaining O.sect.Osmanthus and O.sect.Siphosmanthus Franch.;secondly,creating a new section with O.decorus(Boiss.& Balansa)Kasapligil;then creating a new section with O.yunnanensis(Franch.)P.S.Green and O.serrulatus Rehder;and finally,merging O.sect.linocieroides P.S.Green into O.sect.Osmanthus.These four sections are all strongly supported morphologically,phylogenetically and geographically.[Conclusion]The new revision ensures the phylogenetic relationships of each group are monophyletic and morphologically specific,which makes the species relationships more consistent with the evidence of systematic evolution,and provides an important reference for future scientific research and resource conservation and utilization.关键词
