Surveys to clarify the identification of the alien spatterdock (Nuphar advena) in Great Britain (England, Scotland and Wales) showed that most reported populations included plants that did not have a morphology that agreed with literature accounts of that species. 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.

More than 400 validly published names of vascular plants and Charales honouring William Roxburgh (1751–1815) are listed with the currently accepted names for these taxa and their typification. Some 50 species names commemorating Roxburgh remain in current use. In total, 173 lectotypes and 2 neotypes are designated here to fix the application of the names. A new combination in Centaurium (Gentianaceae) is proposed.

The new rank and combination Berberis extensiflora (Ahrendt) Bh.Adhikari & Harber is proposed based on morphological and molecular studies of the Himalayan species of Berberis (Berberidaceae). Morphologically, Berberis extensiflora differs from B. concinna Hook.f. by its much longer (3–4 cm) inflorescence with 2 or 3 flowers in umbels (vs < 2 cm long solitary flowers) and 10- to 13-seeded berries (vs 5- to 9-seeded berries).

Ocotea bilocellata Baitello, D.B.O.S.Cardoso & P.L.R.Moraes, a species of Lauraceae that is new to science and from the Atlantic rain forest of the state of São Paulo, Brazil, is described and illustrated. The newly described species does not fit in any of the traditionally circumscribed disporangiate Lauraceae genera; rather, we show that it is phylogenetically placed within the Ocotea minarum group, as revealed by nuclear ribosomal ITS and plastid psbA–trnH sequence data.

Begonia (Begoniaceae) is one of the largest angiosperm genera, comprising more than 2000 species; this makes it ideal as a model to investigate the genomic basis of species radiations. 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.

Cytological data resources are crucial to the study and understanding of the evolution of complex taxa. 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.

The nomen nudum Begonia hemicardia Elmer ex Merr. (Begonia sect. Petermannia) was coined by A.D.E. Elmer in 1915. He annotated one of his collections (14366 from Mount Bulusan, Luzon) in the PNH herbarium with the name but did not formally publish it. E.D. 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. However, a combination of characters such as long internodes, large persistent stipules, serrate leaf margins, and long inflorescence with staminate flowers borne on a jointed rachis readily distinguish Begonia hemicardia from these other species, and we validly describe the new species here.
女用海棠半心海棠。海棠(Begonia sect. Petermannia)是由A.D.E. Elmer于1915年创造的。他在PNH植物标本室注释了他的一个收藏(14366年从吕宋岛的Bulusan山)，但没有正式出版它。1923年，梅里尔(E.D. Merrill)认为这个名字是秋海棠(Begonia binuangensis Merr)的同义词。通过对现存和保存标本及相关文献的深入研究，我们发现半心海棠与B. binuangensis是不同的。半心海棠属于菲律宾的一种攀缘海棠，花序腋生，叶多卵形至披针形，近对称，即B. aequata a . gray, B. binuangensis, B. edanoii Merr。B. gracilipes Merr。，拉古纳叶蝉，大叶蝉。， b.s armentosa l.b.m。& Wassh。和B. wenzelii Merr。然而，长节间，大宿存托叶，锯齿叶缘，长花序，雄蕊花在节理轴上，这些特征的组合很容易将半心海棠与其他物种区分开来，我们在这里有效地描述了这个新种。

Begonia is the world’s fastest-growing genus and a focus of intense taxonomic research. To support this, a stable and useful sectional classification is needed. This paper reviews the feasibility and challenges of creating an infrageneric classification for Begonia based on phylogenetic data, and how to overcome phylogenetic and taxonomic conflict. In particular, it (i) tests genus-wide patterns of incongruence between phylogenies based on the nuclear, chloroplast and mitochondrial genomes; (ii) explains organelle inheritance and its contribution to phylogenetic incongruence, and (iii) presents a manifesto for a workable and stable subgeneric classification in light of the above and lays the foundation for a collaborative Begonia Phylogeny Group.

A new cane-like begonia species, Begonia embera Jara & D.Franco, is described and illustrated. Morphological and molecular evidence suggest that it belongs to Begonia sect. Ruizopavonia. This species has been collected only in the Chocó Department, Colombia, growing by streams that flow into the Atrato river. We discuss its phylogenetic relationships, provide illustrations, and present the findings of an assessment of its conservation status.
