The leaves were prepared through cleared, dehydration and paraffin inclusion techniques to observe and describe them. \u0000Results: The Ternstroemia species showed specific features of plants in humid environments, such as thin cuticle, mesophyll with scarce parenchyma palisade, and abundant intercellular spaces in the spongy parenchyma, and specific pigments that help to capture light and serve as protection. The species share a festooned broquidodromous venation pattern, anomocytic stomata, and closed collateral vascular bundle surrounded by perivascular fibers. Both species are differentiated by leaf shape, abundance of collenchyma layers, lenght of palisade parenchyma, and number of stomata per square millimeter on the abaxial surface. \u0000Conclusions: We support and validate some features recorded for Ternstroemia species and reject some previous generalizations made worldwide to the genus.

It consists of a list of taxonomic names of species, genera, and families of vascular plants representing the most comprehensive and integrated list available today. \u0000Questions: How many accepted species does the WCVP include? Is the quality of the included information acceptable? How has the publication of worldwide species names evolved over time? Does the checklist include the species recorded for Mexico? \u0000Studied species: Worldwide species of vascular plants included in the WCVP. \u0000Study site: Worldwide and Mexico. \u0000Methods: A database was created based on the WCVP to answer the research questions. The number of genera and species by taxonomic status (accepted and synonyms) was quantified, some information quality tests were carried out, and the potential number of undiscovered species in the world was estimated using non-parametric techniques. \u0000Results: The WCVP contains 1,233,172 names, of which 418,737 are accepted. It is estimated that around 25 % more unknown species remain to be discovered in the world. The quality of the information contained in the WCVP is quite reliable and complete; only 3 % of Mexican species are not included in the WCVP. \u0000Conclusions: The WCVP synthesizes current taxonomic knowledge in an integrated manner and is useful for systematic and automated analyses. At the country level, at least for Mexico, it stands as an important reference source when attempting to understand and evaluate floristic knowledge.","PeriodicalId":54375,"journal":{"name":"Botanical Sciences","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45066460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En México se registran 15 especies que alguna vez fueron tratadas también bajo los géneros Calamintha o Satureja.

In addition, we discussed some synergies and trade-offs between ecosystem services that were recognized through current palynology in different farming landscapes: biodiversity-based farming systems and chemical input-based farming systems. While pollen morphology and descriptive palynology can provide the basis for crop improvement, biological invasions, and the effect of deforestation on native species, more analytical approaches such as land-use indicators are necessary for sustainable management. In addition, we have included some biocultural aspects to conservation, due to a lack of practical discourse in current palynology.
