Some populations had been misidentified, whereas others were morphologically atypical variants of the UK native Nuphar lutea. Many populations included individuals that had a combination of traits characteristic of both Nuphar advena and N. lutea. Visual examination and measurement of two stamen characters (filament and anther length) show that these plants are sterile, and molecular analysis confirms that these populations include a previously undescribed sterile hybrid between Nuphar advena and N. lutea. Here, we formally describe the hybrid as Nuphar × porphyranthera and provide taxonomic and distribution information on the parental species for comparison, as well as a key to all known Nuphar taxa in Great Britain. Neither Nuphar advena nor Nuphar × porphyranthera show any sign of spreading from sites at which they were almost certainly planted and therefore should not be considered naturalised in Britain.","PeriodicalId":39376,"journal":{"name":"Edinburgh Journal of Botany","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44590655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present the results of the first genus-wide comparative study of plastid genome structure, sequence diversity, and phylogenetics of Begoniaceae, in which 44 complete Begoniaceae plastomes, including those of Begonia’s sister group, Hillebrandia, a monotypic genus endemic to Hawai‘i, and 43 species representing 42 sections of Begonia, were assembled. Our results reveal that Begoniaceae plastome size ranges from 167,123 to 170,852 bp, displaying the typical quadripartite structure. Structures of most Begoniaceae plastomes are highly conserved but differ from the plastomes of the majority of angiosperms in having a unique inverted repeat (IR) expansion, from IRa to large single copy (LSC), resulting from a duplicated fragment of the trnH–GUG gene to the trnR–UCU gene. Additionally, comparison between plastomes of Hillebrandia and Begonia shows that the former genus has fewer simple sequence repeats than most Begonia species analysed, suggesting that species of Begonia have more repetitive and dynamic plastomes than those of its sister genus. We also identified six highly variable regions suitable for phylogenetic analysis and as potential DNA barcodes for species identification. Our robust hypothesis of plastome phylogenomic relationships provides new insights into infrageneric classification and highlights potential classification issues in Begonia.

Recent research on the genus Begonia L. has provided a robust phylogenetic background for the analysis of evolutionary patterns across the group and has established that Begonia is variable in genome size and chromosome number. This paper provides an overview of the genome structural variation present in Begonia and an updated chromosome number and genome size dataset for the genus. Chromosome numbers of more than 400 species are presented and discussed within their current taxonomic and phylogenetic context. A more complete chromosome number dataset is available for Neotropical and Asian Begonia sections than for those from Africa. The distribution of chromosome numbers across phylogenetic trees supports the idea of Begonia sections as natural groups, because most variation is found between sections rather than within them. Some larger Begonia clades were found to have larger chromosome number variation. Moreover, groups with the most variable chromosome numbers belong to some of the taxonomically complex or unresolved Begonia sections. Genome size variation was found not to correlate with changes in chromosome number. It suggests that Begonia genome dynamics are caused not only by large-scale duplications, rearrangements, and changes in ploidy levels but also by changes in the repetitive fraction of the genome, which probably cause changes in chromosome size. This could potentially play an important role in species radiations.","PeriodicalId":39376,"journal":{"name":"Edinburgh Journal of Botany","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42682858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Merrill in 1923 recognised the name as a synonym of Begonia binuangensis Merr. After thorough studies of living and preserved specimens and the relevant literature, we found Begonia hemicardia to be different from B. binuangensis. Begonia hemicardia is allied to a group of climbing Begonia in the Philippines with axillary inflorescences and numerous, subsymmetrical, ovate to lanceolate-ovate leaves, namely B. aequata A.Gray, B. binuangensis, B. edanoii Merr., B. gracilipes Merr., B. lagunensis Elmer, B. megacarpa Merr., B. sarmentosa L.B.Sm. & Wassh. and B. wenzelii Merr.
