Dracula anthracina has remained as a charismatic market-valued species with no information on its natural habitat. We found the precise location of D. anthracina in explorations across the Colombian eastern Cordillera. Our observations of wild populations and cultivated plants suggest that D. nigritella should be reduced to a synonym of D. anthracina based on morphological characters. Furthermore, the species seems to be rare, geographically restricted, and has small populations. Hence, we suggest that D. anthracina should be considered of conservation concern and should be excluded from Ecuador's flora. Resumen Trece especies (18%) del género Dracula en Colombia carecen de información básica de su biogeográfica y ecológica. Dracula anthracina es una especie de alto valor en el mercado, cuya información del habito natural ha permanecido históricamente obscuro. Durante exploraciones de la orquideoflora de la cordillera oriental de Colombia, encontramos la ubicación de D. anthracina. Tras estudiar los caracteres morfológicos de individuos de D. anthracina en su hábitat natural y material cultivado, encontramos que D. nigritella debe ser reducido a sinónimo de D. anthracina. Nuestro muestreo aleatorio sugiere que esta Dracula es rara, con distribución geográfica restringida y poblaciones pequeñas. De tal manera, D. anthracina como especie comercializada debe ser considerada como una especie de conservación endémica de Colombia y debe ser excluida de la flora de Ecuador.","PeriodicalId":54438,"journal":{"name":"Systematic Botany","volume":"48 1","pages":"200 - 207"},"PeriodicalIF":1.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45949911","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}

Phylogenetic relationships among these Iris were reconstructed based on sequence data from 110 nuclear markers (coding regions) and plastomes using Bayesian inference and maximum likelihood methods. Best trees based on plastome and combined datasets resolved Iris subgenus Xiphium and I. xiphium as not monophyletic while nuclear and all-gene (combined nuclear and plastid coding regions) datasets resolved the subgenus as monophyletic but I. xiphium as not monophyletic. Topology tests indicated the alternative hypothesis of a monophyletic subgenus is not rejected by the combined dataset while a monophyletic I. xiphium is rejected. Topology tests also showed the hypothesis of a polyphyletic subgenus is rejected by the nuclear and all-gene datasets, however, a monophyletic I. xiphium is not rejected by these two datasets. We hypothesize that the subgenus is monophyletic based on these analyses, morphology, and biogeography, and that uneven patterns of missing data is a likely reason for topological incongruence among datasets. A previously suggested informal group within the subgenus was supported. Patterns of relationships among species suggest multiple exchanges between the African and European continents but also the importance of the Strait of Gibraltar as a barrier to genetic exchange.","PeriodicalId":54438,"journal":{"name":"Systematic Botany","volume":"48 1","pages":"208 - 219"},"PeriodicalIF":1.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45579869","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}

Because the subgenus Glycine represents the tertiary gene pool for one of the world's most important crops, the group has been the target of collection and study for decades, resulting in a steady growth in the number of formally recognized species, from six in the 1970s to over 20 at present, as well as a number of additional informal taxa. These studies have also produced a system of nuclear diploid “genome groups” corresponding to clades in molecular phylogenies. The aptly named G. remota is known only from a single isolated population in the Kimberley region of northwestern Australia and was named only in 2015. The species is unique within Glycine in having unifoliolate leaves; its discoverers hypothesized that G. remota, if diploid, is related to species of the I-genome that are also native to the Kimberley region. We produced low coverage short-read genome sequencing data from an herbarium specimen of G. remota. Genome size estimates from the sequencing data suggests that G. remota is a diploid, while ploidy estimation is inconclusive likely due to the history of whole genome duplication in Glycine. Phylogenomic analyses of genome-wide SNPs, as well as phylogenetic analyses of the low copy nuclear gene (histone H3D), the entire ribosomal RNA cistron, and the internal transcribed spacer all placed the species unequivocally in the diploid I-genome clade. A complete plastome sequence was also generated and its placement with a plastome phylogeny is also consistent with membership in the I-genome.","PeriodicalId":54438,"journal":{"name":"Systematic Botany","volume":"48 1","pages":"78 - 87"},"PeriodicalIF":1.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46639145","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}
