{"title":"Aquatic Plants of Northern and Central Europe Including Great Britain and Ireland","authors":"Harold W. Keller","doi":"10.17348/jbrit.v18.i1.1358","DOIUrl":"https://doi.org/10.17348/jbrit.v18.i1.1358","url":null,"abstract":"The introduction takes the reader back to early explorers of river systems and aquatic habits in the 1800s for the geographical areas highlighted in the book. Pages are filled with color photographs illustrating plant morphological examples along with taxonomic key couplets. Each species is profusely illustrated with line drawings and color photographs along with distribution maps. There is an illustrated glossary (pp. 728–733) that aids in interpreting the species descriptions. A literature citation section (pp. 734–738) is organized by topical headings, e.g., Species Identification and Biology. The Index of Latin Names locates the species by page numbers. I found this book easy to use because the authors have focused their attention on organization, function, and usability for the public, as well as aquatic taxonomists. Everything about this book is first class! The size and weight will limit its use in the field and will be more appropriate for in house laboratory or classroom use. The design, layout, printing, binding, and overall quality of the text is of exceptional high quality. I highly recommend this book for botanists interested in European aquatic habitats at a bargain price.","PeriodicalId":17307,"journal":{"name":"Journal of the Botanical Research Institute of Texas","volume":"102 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141666285","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}

{"title":"A morphological study on the question of the hybrid origin of Astrophytum coahuilense (Cactaceae)","authors":"R. R. Montanucci","doi":"10.17348/jbrit.v18.i1.1346","DOIUrl":"https://doi.org/10.17348/jbrit.v18.i1.1346","url":null,"abstract":"Two alternative hypotheses may explain the origin of Astrophytum coahuilense. One hypothesis is that A. coahuilense is an ancient diploid hybrid derived from interbreeding between A. capricorne and A. myriostigma. An alternative is that A. coahuilense arose via allopatric speciation and its similarity to A. myriostigma in vegetative characters is due to convergent evolution. The two hypotheses are tested, applying univariate analysis and Non-metric Multidimensional Scaling analysis to morphological datasets. Univariate analysis, which is based on 13 vegetative and 10 reproductive characters, shows that the morphology of A. coahuilense is complex, consisting of a combination of vegetative and reproductive characters shared with both A. capricorne and A. myriostigma as well as several intermediate traits. Furthermore, the morphology of A. coahuilense lacks unique, fixed characteristics. Non-metric Multidimensional Scaling analysis of 15 characters (three vegetative and 12 reproductive traits) produced a two-dimensional scatterplot in which the cluster representing A. coahuilense occupies a position intermediate between the clusters of the two parental species along Dimension 1. Thus, both analyses support the hypothesis that Astrophytum coahuilense originated through hybridization between A. capricorne and A. myriostigma. Biological and ecological factors that may have facilitated homoploid hybrid speciation are discussed.","PeriodicalId":17307,"journal":{"name":"Journal of the Botanical Research Institute of Texas","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663847","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}

Anteriormente se tenían registradas como válidas cerca de 60 especies, este género no ha sido revisado en su totalidad en los últimos años. La última revisión completa data de 1960 y fue realizada por Sauer, sin embargo, desde esa fecha hasta el presente, se han acumulado muchas colectas de lugares especialmente ricos en especies como el Centro y Occidente de México y el norte de Centroamérica, dando lugar a una acumulación de especímenes pobremente curados que, sin duda, representan algunas ampliaciones interesantes en las distribuciones, así como la adición de especies nuevas para la ciencia. Algunos de los taxones originales eran poco conocidos y otros más tenían problemas nomenclaturales y taxonómicos, habiendo sido sinonimizados por Sauer y restituidos en este trabajo. Por lo que creemos que hemos resuelto los problemas asociados a los tipos de la mayoría de las especies propuestas por Martens y Galeotti para México y Centroamérica. Se revisaron especímenes de diversos colectores acumulados cuidadosamente por más de 30 años en el Herbario Nacional de México (MEXU) por Mario Sousa Sánchez, así como material que fue detectado por él como posibles especies nuevas a través de sus visitas a otros herbarios principalmente al Jardín Botánico de Missouri (MO), la Universidad de Texas, Austin (LL) y el Jardín Botánico de Nueva York (NY); se consultó la literatura especializada, antigua y reciente, especialmente aquella referente a la publicación de nuevos taxones dentro del género. Se encontró que hay, en todo el material de herbario revisado, al menos 11 especies nuevas para la ciencia, que al menos cinco nombres antiguos sinonimizados por Sauer corresponden a especies claramente distinguibles y que varias especies presentes en el Centro y Sur de México se extienden hasta la parte norte de Centroamérica (Guatemala, Honduras y, en menor medida, El Salvador y Nicaragua), se presentan claves para los cuatro subgéneros y claves para las especies dentro de cada subgénero presentes en la región. Tres de los cuatros subgéneros están presentes en el área de estudio, faltando únicamente el subgénero Maunaloa, endémico a Hawái.","PeriodicalId":17307,"journal":{"name":"Journal of the Botanical Research Institute of Texas","volume":"17 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664173","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}

Direct destruction of species and habitats has been a primary driver of declines, though climate change and associated sea level rise are expected to accelerate loss. The flora of low-lying, relatively isolated islands is especially threatened when high species richness intersects with vulnerability to sea level rise. The Florida Keys represent a hotspot for cactus diversity in the eastern United States, with eight species recognized, three of which are endemic to the islands. Though not endemic to the islands, the Key Largo tree cactus (Pilosocereus millspaughii) was known in the United States from only a single population in the Florida Keys. Its decline and imminent extirpation correspond with rising sea levels in the region. The other cacti in the region, and all rare plants in the Florida Keys, are threatened with a similar fate.","PeriodicalId":17307,"journal":{"name":"Journal of the Botanical Research Institute of Texas","volume":"110 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141665734","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}
