Despite relatively recent revisions, the genus is still deemed complex and its species difficult to recognize due to often overlapping circumscriptions. A crucial step in species delimitation and correct application of names is the analysis of types. Advances in the digitization of biological collections and bibliographical material have facilitated the access to type collections, but the information available is still fragmented and, in many cases, equivocal. The aim of this work was to perform a typological assessment of the names of Copaifera based on material from the New World, providing a nomenclatural revision toward a better understanding of its species and a broad taxonomic revision of the genus.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":"107 1","pages":"467 - 479"},"PeriodicalIF":1.9,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43473545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Raven","doi":"10.3417/2022735","DOIUrl":"https://doi.org/10.3417/2022735","url":null,"abstract":"Abstract Evolutionary shifts in breeding system are thought to have played key roles in the diversification of many lineages of plants, including the evening primrose family (Onagraceae), which includes the genus Oenothera L. Diversification in Oenothera has been accompanied by frequent breeding system shifts, but it is not clear whether these differences are due to shared evolutionary history or reflect repeated independent adaptations to varying ecological conditions. In this study, we focus on “Subclade B,” one of two primary clades within Oenothera, and combine phylogenetic reconstructions and breeding system data to evaluate evidence for multiple transitions to self-compatibility. This study includes 46 of the 58 named taxa (species and subspecies) of Oenothera Subclade B. Some taxa were sequenced in earlier analyses, available from GenBank, one was resampled here to add new sequences, and 28 taxa are newly sequenced here. We base our phylogeny on sequencing of portions of four chloroplast markers (rps16, ndhF, trnL-F, and rbcL) and two nuclear genes (ITS and ETS). We used pollination tests to verify or determine the breeding system of these taxa. Our phylogeny supports the current classification of Oenothera with minor changes and provides greater insight and clarity to the relationships of these species. Our results provide support for the monophyly of most of the sections in Oenothera Subclade B, as well as greater resolution for topology within sections Gaura (L.) W. L. Wagner & Hoch, Hartmannia (Spach) Walpers, Kneiffia (Spach) Walpers, and Megapterium (Spach) Walpers. Relationships among these monophyletic lineages, and the placement of sections Paradoxus W. L. Wagner and Peniophyllum (Pennell) Munz, and of the allopolypoid O. hispida (Benth.) W. L. Wagner, Hoch & Zarucchi, are not uniformly well-supported and need further clarification, but these phylogenetic uncertainties had minimal impact on the inference of transitions in self-compatibility in Subclade B. We use maximum likelihood, Bayesian inference and stochastic character mapping to estimate the minimum and maximum number of transitions necessary to explain the phylogenetic distribution of self-compatible lineages. Our results confirm at least 12 and possibly up to 15 independent transitions from self-incompatibility to self-compatibility in Oenothera Subclade B. This lability in breeding system, which is also seen broadly across Oenothera, lends strong support to the hypothesis that this trait plays a key role in the diversification of the genus.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":"107 1","pages":"405 - 421"},"PeriodicalIF":1.9,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46256576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Daphniphyllum is a morphologically homogeneous group of evergreen shrubs to trees divided into three sections: Daphniphyllum, Lunata T. C. Huang, and Staminodia Hurusawa. While the medicinal value of the Daphniphyllaceae has been explored in many studies, the understanding of their evolutionary history and infrageneric classification is still limited. To test the infrageneric classification and to examine evolutionary and classification hypotheses proposed by previous taxonomic studies, we reconstructed multilocus phylogenies by sampling 55.6% (= 20/36) of taxa in the genus based on both chloroplast (psbA-trnH spacer and trnL intron) and nuclear ITS (ITS1, 5.8S rDNA, and ITS2) regions. Our data do not support the monophyly of the three sections. Our results indicate that some hybridization events might have occurred in the evolutionary history of the genus. Moreover, our results support the classification hypotheses of D. glaucescens Blume in a strict sense but not in a broad sense. In addition, we elevate D. ×lanyuense (T. C. Huang) M. S. Tang, S. H. Liu & Yuen P. Yang, stat. nov., from varietal rank to species based on our results. Two putative natural hybrids, D. ×lanyuense and D. teijsmannii Zoll. ex Teijsm. & Binn., and their putative parental taxa are also revealed in our study.
