Through new and comprehensive use of Engelmann’s personal papers, letters, and informal daily correspondence housed at the Missouri Botanical Garden, this essay offers a reappraisal of the botanist’s place in the history of grape science, the international wine industry, and the late 19th-century phylloxera crisis, as well as the use of wine in his medical practice in St. Louis. Engelmann’s work on Vitis L. illustrates that he served as the hub of a wide wheel of scientific inquiry, positioning U.S. botanists as experts for prestigious international audiences. His contributions in three related arenas—botanical discovery and naming of Vitis species, service to the wine industry, and as a physician attending to St. Louis families’ health by prescribing wine—were all crucial facets of U.S. national expansion. Like many other wine enthusiasts, Engelmann and his adopted countrymen were interested in defining U.S. viticulture and the nation itself as projects concerned with both wild, resilient native stock and cultivated refinement.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135569479","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}

(Polypodiaceae), a tropical American fern genus. Our work is based on a morphological analysis of 56 characters recorded from 2167 specimens deposited in 41 herbaria. Field trips were carried out in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, and Peru, where observations on the habit and habitat of several species were made. Digital images were also consulted. A total of 260 names were found and their nomenclatural types were studied, resulting in the lectotypification of 47 names (first-step 30, second-step 17 names). We recognize 37 species and five hybrids in Serpocaulon; one of the hybrids is given a new status (S. ×semipinnatifidum (Fée) A. R. Sm.) and another one is described (S. ×tabuleirense D. Sanín & Salino). Moreover, 19 names are newly synonymized, five species are excluded, 17 names are considered as of uncertain application, and five as nomina nuda. We document for 22 species a total of 62 chorological novelties in different countries. The elevational range of the genus is 0–4200 m. The Andes of Ecuador and Colombia are the main center of diversity and endemism; secondarily, the Atlantic Rain Forest of Brazil has five endemic species. We provide a taxonomic key, descriptions, discussions, local names, uses, illustrations, photographs of the plants in the field, microphotographs of the rhizome scales and the spores, and distribution maps of all species.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883573","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}

The species of the genus that inhabit Chile are mostly endemic to that country and are phylogenetically closely related to species from the west coast of the United States of America and Australia. Taxonomic studies of the North American and Australian lineages of Eryngium are in press or in preparation. However, the Eryngium species from Chile have not been revised taxonomically for more than a century. Moreover, many of the species of the genus endemic to Chile show restricted distributions and, therefore, deserve particular attention to evaluate if they are in any category of threat in order to develop conservation policies. The objective of this study is to perform a taxonomic revision of the species of Eryngium from Chile, including an analysis of their conservation status. For this purpose, the vegetative and reproductive morphology and the geographic distribution and habitat of ca. 750 herbarium specimens were analyzed. In addition, the conservation status of the species was evaluated following the Red List categories and criteria of the International Union for Conservation of Nature. In total, 17 species of Eryngium were recognized in Chile, of which 15 are endemic to that country and two also grow in Argentina. A key for the recognition of species is provided. For each species, a list of accepted synonyms, a morphological description, illustration, distribution map, habitats, phenology, and vernacular names are presented. Six new synonyms are proposed (Eryngium polyrhizum Clos and all varieties of E. depressum Hook. & Arn. are synonymized with E. depressum, E. amethystinodes Kuntze is synonymized with E. rostratum Cav., and E. delarocheanum H. Wolff is synonymized with E. paniculatum Cav. & Dombey ex F. Delaroche), and nomenclature problems were analyzed and resolved, including the typification of 23 names. The distribution ranges of six species (Eryngium anomalum Hook. & Arn., E. coquimbanum Phil. ex Urb., E. depressum, E. humifusum Clos, E. pulchellum Phil., and E. rostratum) are rectified. Aproximately 60% of the Eryngium species from Chile belong to a category of threat, and most of them are critically endangered, so they should be special targets for conservation.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43475608","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}

However, some studies show contrasting delineations of the SC/SW North American provinces that could be better determined using quantitative methods. We aimed to find spatial patterns of a set of plants in the SC/SW United States by conducting endemicity analysis (EA) on different scales. We first built a dataset with 81,965 specimen point records of 400 species from 174 genera and 61 families of angiosperms and two genera of gymnosperms using digitized specimen data from iDigBio. We then performed EA at four different scales to identify the areas of endemism (AoEs). \u0000We obtained 28 AoEs with different cell sizes by selecting each AoE under the grid size that yielded the highest number of high-scoring species. The study region split into two significant centers of accumulation of nested or partially overlapping AoEs: the SW and SC consensus areas. In these parts of the Nearctic region, many genera/clades, among those in the dataset, showed a geographic split into western and eastern clades. The split corresponded to an environmental and physical barrier known as Cochise Filter Barrier. The Sonora–Mojave arid center, parts of South Texas, and the Chihuahuan Desert harbor basally branching taxa of several genera and even families, based on the observations of some species, which allowed identification of the AoEs.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45691927","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}

Li were originally monotypic with M. peltata (Merr. & Chun) W. T. Wang and D. poilanei (Pellegr.) W. T. Wang & Z. Y. Li, respectively. Recent molecular phylogenetic research expanded Deinostigma to include several species previously transferred from Chirita D. Don to Primulina Hance. However, the relationship between Metapetrocosmea and Deinostigma has not been well addressed. In the present study, the type species of Metapetrocosmea and Deinostigma were sampled together with related taxa, and the systematic relationships were reexamined using the nuclear ribosomal internal and external transcribed spacer regions (ITS and ETS) and four chloroplast regions (rpL32-trnL, rps16, trnH-psbA, trnL-F). Phylogenetic analyses demonstrate that M. peltata is embedded in the species of Deinostigma and sister to D. poilanei. All of these species form a highly supported branch, i.e., Metapetrocosmea–Deinostigma clade, which is sister to Oreocharis Benth. Morphological analyses show that species in the Metapetrocosmea–Deinostigma clade share a series of morphological traits, i.e., alternate leaves, arcuate filaments, densely lanate anthers with the hair surface covered with granular or vermiform appendages, bilobed stigma that vary from dorsal to ventral and almost equal in size to a dorsal-ventral oblique lamella with the dorsal one sterile, hooked hairs and T-shaped glandular hairs occurring on the whole plant, and riblike seed surfaces. Both molecular and morphological evidence strongly suggest that the Metapetrocosmea–Deinostigma clade is monophyletic and should be combined into a single genus, i.e., Metapetrocosmea W. T. Wang. Therefore, we present a taxonomic treatment for this group.","PeriodicalId":55510,"journal":{"name":"Annals of the Missouri Botanical Garden","volume":"107 1","pages":"447 - 466"},"PeriodicalIF":1.9,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45570244","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}
