Antecedentes: El género Solanum (Solanaceae) incluye hierbas anuales, hierbas perennes y epífitas, lianas herbáceas, bejucos, sufrútices, arbustos y árboles. Las flores son pentámeras, gamosépalas y gamopétalas con corolas estrelladas, pentagonales o rotadas y anteras dehiscentes por poros apicales. El fruto es una baya. Solanum es uno de los 10 géneros más ricos de angiospermas e incluye a 1,234 especies. México es un centro de diversificación del grupo, pero su variación morfológica y la existencia de un número grande de nombres publicados dificultan su identificación. Preguntas: ¿Cuántas especies de Solanum crecen en México? ¿Qué características morfológicas son importantes para su identificación? Taxón de estudio: Solanum Sitio de estudio: México Métodos: Se revisaron los ejemplares de Solanum depositados en 15 herbarios y 10 colecciones digitales. Los nombres se validaron en Tropicos, The Plant List, International Plant Names Index y Solanaceae Source. También se obtuvieron e imprimieron los protólogos y los tipos nomenclaturales depositados en Global Plants. Para la elaboración de las claves, observamos la variación de caracteres vegetativos y reproductivos y su distribución geográfica. Resultados: Identificamos la presencia de 134 especies de Solanum agrupadas en 22 secciones. Elaboramos claves para las secciones y para las especies dentro de cada sección. Por último, mostramos fotografías representativas del género. Conclusiones: México es un centro de diversificación de Solanum y el grupo, a su vez, es un buen representante de la riqueza de angiospermas mexicanas. Claves para Solanum de México facilitarán su identificación en campo y herbarios.

This work builds on the outputs of a collector data-mining exercise applied to GBIF mobilised herbarium specimen metadata, which uses unsupervised learning (clustering) to identify collectors from minimal metadata associated with field collected specimens (the DarwinCore terms recordedBy, eventDate and recordNumber). Here, we outline methods to integrate these data-mined collector entities (large scale dataset, aggregated from multiple sources, created programatically) with a dataset of author entities from the International Plant Names Index (smaller scale, single source dataset, created via editorial management). The integration process asserts a generic "scientist" entity with activities in different stages of the species description process: collecting and name publication. We present techniques to investigate specialisations including content - taxa of study - and activity stages: examining if individuals focus on collecting and/or name publication. Finally, we discuss generalisations of this initially herbarium-focussed data mining and record linkage process to enable applications in a wider context, particularly in zoological datasets.

We present revised estimates of the numbers of accepted species of flowering plants (369,434), seed plants (370,492), vascular plants (383,671) and land plants (403,911) based on a recently de-duplicated version of the International Plant Names Index and rates of synonymy calculated from the seed plant families published in the World checklist of selected plant families. Alternative approaches to estimating or calculating the number of accepted plant species are discussed and differences between results are highlighted and interpreted.

The Royal Botanic Garden Edinburgh holds a number of small and understudied collections in the glasshouses at Edinburgh about which relatively little is known. This paper introduces one of these genera. A brief introduction and history is given of the genus Diplycosia Blume. An outline of the literature and a summary of their distribution, along with an overview and history of the collections held at Edinburgh, are also presented, as are cultivation notes. All plant names in this paper have been cross-referenced using the International Plant Names Index website (International Plant Names Index, 2010).

The taxonomic foundation of a new regional flora or monograph is the reconciliation of pre-existing names and taxonomic concepts (i.e., variation in usage of those names). This reconciliation is traditionally done manually, but the availability of taxonomic resources online and of text manipulation software means that some of the work can now be automated, speeding up the development of new taxonomic products. As a contribution to developing a new Flora of Alaska (floraofalaska.org), we have digitized the main pre-existing flora (Hultén 1968) and combined it with key online taxonomic name sources (Panarctic Flora, Flora of North America, International Plant Names Index - IPNI, Tropicos, Kew’s World Checklist of Selected Plant Families), to build a canonical list of names anchored to external Globally Unique Identifiers (GUIDs) (e.g., IPNI URLs). We developed taxonomically-aware fuzzy-matching software (matchnames, Webb 2020) to identify cognates in different lists. The taxa for which there are variations between different sources in accepted names and synonyms are then flagged for review by taxonomic experts. However, even though names may be consistent across previous monographs and floras, the taxonomic concept (or circumscription) of a name may differ among authors, meaning that the way an accepted name in the flora is applied may be unfamiliar to the users of previous floras. We therefore have begun to manually align taxonomic concepts across five existing floras: Panarctic Flora, Flora of North America, Cody’s Flora of the Yukon (Cody 2000), Welsh’s Flora (Welsh 1974) and Hultén’s Flora (Hultén 1968), analysing usage and recording the Region Connection Calculus (RCC-5) relationships between taxonomic concepts common to each source. So far, we have mapped taxa in 13 genera, containing 557 taxonomic concepts and 482 taxonomic concept relationships. To facilitate this alignment process we developed software (tcm, Webb 2021) to record publications, names, taxonomic concepts and relationships, and to visualize the taxonomic concept relationships as graphs. These relationship graphs have proved to be accessible and valuable in discussing the frequently complex shifts in circumscription with the taxonomic experts who have reviewed the work. The taxonomic concept data are being integrated into the larger dataset to permit users of the new flora to instantly see both the chain of synonymy and concept map for any name. We have also worked with the developer of the Arctos Collection Management Solution (a database used for the majority of Alaskan collections) on new data tables for storage and display of taxonomic concept data. In this presentation, we will describe some of the ideas and workflows that may be of value to others working to connect across taxonomic resources.
