New Insights into the Phylogeny of Angelica and its Allies (Apiaceae) with Emphasis on East Asian Species, Inferred from nrDNA, cpDNA, and Morphological Evidence

摘要: Classification of Angelica and its allies is complex controversial, with previous phylogenetic studies restricted to examina- tion small numbers taxa using only nrDNA ITS sequences. In this study, analyses ETS sequences, cpDNA sequences (rps16 intron, rps16-trnK, rpl32-trnL, trnL-trnT), morphological data, supplemented by observations fruit anatomy micromorphology, were used ascertain evolutionary relationships confirm generic boundaries within s.l. (including Angelica, Archangelica, Coelopleurum, Czernaevia, Ostericum), emphasis on East Asian members. Most species fall into two major, disparate clades, the Ostericum clade group, latter comprising five major lineages that are distinguished both molecularly morphologically: s.s. Czernaevia), Glehnia, a newly identified Littoral clade. A North American was also in trees. Taxonomic realignments will be required, as many outside four occur group (A. hirsutiflora, A. oncosepala, paeoniifolia, sinensis). The contains predominantly comprises lineages, which represent plants exclusively from eastern Himalayas; each these can defined morphologi- cally. results obtained significantly different traditional treatments provide new insights phylogeny classification group.
