The latter is proposed here to include eight genera. Amongst these, the recently described genus <i>Oreomecon</i> is phylogenetically a sister group to <i>Meconopsis</i>, a genus from Himalaya and central China, which is reviewed here as including 95 species and 21 subspecies. By contrast, <i>Oreomecon</i> has a circumpolar northern alpine and Arctic distribution, including incompletely understood taxa, many threatened by climatic warming. Based on a review of literature and phylogenies, it is proposed here that <i>Oreomecon</i> includes 68 species and 29 subspecies. <i>Oreomeconaurantiaca</i>, <i>O.cornwallisensis</i>, <i>O.keelei</i>, <i>O.ochotensis</i> and <i>O.uschakovii</i>, 29 subspecies and four varieties are placed in <i>Oreomecon</i> here, 29 of these as recombinations, the remaining ones as nomenclatural novelties. A total of 21 existing <i>Oreomecon</i> names are placed into synonymy. The taxonomically challenging <i>O.alpina</i> group from Central Europe is treated as comprising three species, with the remaining entities positioned at the subspecies level pending further studies. The much-studied Nordic species <i>O.radicata</i> is treated with eight subspecies here, based on morphometric studies, whereas four accepted entities are provisionally recombined at the variety level. The name <i>Papavertenellum</i> and the basionyms of <i>Oreomeconalborosea</i>, O.alpinasubsp.corona-sancti-stephani, O.alpinasubsp.degenii, <i>O.anomala</i>, O.lapeyrouseanasubsp.endressii, O.lapponicasubsp.laestadiana and <i>O.nivalis</i> are lectotypified here. Two replacement names, Oreomeconalpinasubsp.markgrafiana and O.radicatasubsp.knabeniana, are introduced. <i>Papaver</i>, as currently understood, is recircumscribed here to represent four genera. The isolated sectionHorrida, from southern Africa, is raised to genus level with the new name <i>Afropapaver</i> and its only species is recombined as <i>Afropapaveraculeatum</i>. Papaversect.Californica from California and adjacent Mexico is treated as the genus <i>Stylomecon</i>. The name has been applied to one of the two species of this group and we now recombine the other one as <i>S.crassifolia</i>, based on an older basionym replacing <i>Papavercalifornicum</i>. <i>Papavercambricum</i> is accepted in its alternative position as the monotypic genus <i>Parameconopsis</i>. As reviewed here, <i>Papaver</i> comprises 59 species and 14 subspecies and is only the third-largest genus in the group. Based on the distribution of its closest relatives and oldest sections, it is hypothesised here that <i>Papaver</i> arose in the western Mediterranean. Its poricidal capsule dehiscence serves as an excellent adaptation to seed dispersal in open, arid environments, possibly explaining its later success in the Türkiye-Caucasus-Middle East area, where its diversity both at species and section level is highest.</p>","PeriodicalId":20070,"journal":{"name":"PhytoKeys","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11538858/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our phylogenetic analysis confirms the monophyly of <i>Bupleurum</i> with strong support. Both ITS and chloroplast dataset divided the <i>Bupleurum</i> in East Asia into East Asia Group I and East Asia Group II in this study. The divergence time and ancestral area reconstruction of ITS dataset indicated that the <i>Bupleurum</i> originated in the Mediterranean basin and its adjacent areas around 50.33 Ma. subg.

The character reconstruction showed that the morphological characters and altitude distribution analyzed in this study exhibit a scattered distribution in East Asian Group I and East Asian Group II. Additionally, diversification rate analysis shows that the East Asian Group I and East Asian Group II exhibited no significant shifts in diversification rates in the evolutionary history according to ITS and combined dataset.
