Special Issue Information

Dear Colleagues,

 We are pleased to announce a forthcoming Special Issue of Plants dedicated to exploring innovative approaches and emerging insights into plant biogeography, systematics, and taxonomy. These interrelated fields are experiencing a renaissance driven by advances in phylogenetics, genomics, ecological modelling, and data integration. This Issue seeks to highlight studies that challenge traditional paradigms, propose novel hypotheses, and offer refined methodologies for understanding the origins, distributions, and classifications of biodiversity across spatial and temporal scales.

We welcome original research articles that provide new theoretical frameworks, integrative taxonomic revisions, or biogeographic reconstructions informed by molecular, morphological, ecological, or paleontological data. Contributions that apply interdisciplinary approaches—linking taxonomy to conservation, phylogenetics, or biogeography—are especially encouraged. Case studies from underexplored regions and taxa, as well as contributions addressing the implications of taxonomic and biogeographic uncertainty, are highly valued.

This Special Issue aims to foster dialogue across disciplines and promote forward-thinking research that refines our understanding of biological diversity. Manuscripts will undergo rigorous peer review and will be published on a rolling basis upon acceptance. We invite researchers from around the world to submit their contributions and be part of this timely and impactful collection.

Dr. Rafael Felipe de Almeida

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The historical background of studies on Brazilian Orchidaceae dates back almost 400 years. In this review, we provide an overview of the current knowledge on Brazilian Orchidaceae across three thematic axes: 1. diversity, distribution, and endemism; 2. taxonomy and systematics; and 3. structural, genetic, and ecological characterization. Brazil harbors five naturalized and 202 native genera, of which 23 are endemic to the country. There are currently 2515 accepted species (out of 9907 species names). Among the 7218 synonyms, 3915 are heterotypic, yielding a synonymy rate of 60.9%. Brazil is the second country in orchid endemism with 1540 endemic species. Apostasioideae is not present in Brazil, but the remaining four orchid subfamilies are represented by 16 tribes and 23 subtribes. The richest phytogeographic domain is the Atlantic Forest (1398 spp.), followed by the Amazon Forest (784 spp.) and Cerrado (656 spp.). The richest subtribes are Pleurothallidinae (642 spp.), Laeliinae (397 spp.), and Oncidiinae (283 spp.). Moving beyond a purely taxonomic and phylogenetic framework, this work offers a comprehensive synthesis of Brazilian Orchidaceae, encompassing the state of the art in cytogenetics, anatomy, population genetics, reproductive biology, and pollination. Despite these advances, there are pronounced disparities among regions, taxa, and research approaches. The persistence of these shortfalls highlights the urgent need for integrative research frameworks. Future progress in Brazilian orchidology depends on the strengthening of collaborative networks and interdisciplinary approaches. Full article
