Special Issue Information

Dear Colleagues,

We are proud to present this Special Issue of Plants on “Plant Diversity and Classification” as an opportunity to publish recent articles on the subject. This Special Issue addresses crucial topics for the understanding and conservation of plant biodiversity. Plant systematics involves the identification, description and categorization of species, providing the basis for other biological disciplines.

Taxonomy is the science that defines and names groups of organisms, clarifying the evolutionary relationships between them. Botanical nomenclature, governed by international rules, ensures that each species has a unique and globally recognized scientific name, avoiding confusion and promoting clear and efficient communication between researchers.

At present, the importance of this area is evident in biodiversity conservation, agriculture, and ecological studies. Understanding the diversity and relationships between plants allows for more effective strategies for ecosystem preservation, sustainable use, and restoration.

Looking ahead, these disciplines are essential in discovering new species, monitoring climate change, and developing biotechnologies. Accurate plant classification can also reveal potential medicinal, nutritional, and industrial uses, driving innovations benefiting humanity.

Therefore, this Special Issue not only celebrates advances in the field but also reinforces the ongoing need for research and updates in the study of plant diversity, which is vital for sustainability and global well-being..

The Catostemma clade comprises three genera: Aguiaria, Catostemma, and Scleronema. These genera are representatives of the tribe Adansonieae, and are part of the subfamily Bombacoideae of the Malvaceae family. Taxonomic studies of these genera are scarce and limited to isolated publications of new species or regional floras. We reviewed their taxonomy, morphology, and geography, and assessed gaps in our knowledge of this group. We carried out a bibliographic survey, an analysis of herbarium collections, and collected new material in Brazilian forests. Here, we provide an identification key, nomenclatural revisions, morphological descriptions, taxonomic comments, geographic distribution maps, illustrations, and analyses of the conservation status for all species. We also discuss probable synapomorphies of the clade, to advance our understanding of phylogenetic relationships within the Adansonieae tribe of Bombacoideae. In total, we recognize 16 species: 1 Aguiaria, 12 Catostemma, and 3 Scleronema, of which 7 are endemic to Brazil, 1 to Colombia, and 1 to Venezuela. Two species are ranked as Critically Endangered (CR), and four as Data Deficient (DD). Full article

The study of flora is crucial for conserving natural resources and assessing human impact on the environment. This paper explores floristic diversity, the role of plants, and the integration of technology in botanical research. In the studied area, 462 plant species were identified. Bioform analysis revealed a predominance of hemicryptophytes (45.45%) and therophytes (26.19%), suggesting a warm climate and significant zoo-anthropogenic influences. Other bioforms were present in lower percentages. Most plant species in Teleorman County are mesophilic (39.39%) and mesoxerophilic (30.95%), indicating adaptation to moderate or slightly dry environments. Regarding temperature affinity, the majority are micromesotherms (62.98%), suited for mild thermal conditions. Soil reaction analysis showed a preference for weakly acidic neutrophilic (39.82%) and euryionic (33.76%) soils, indicating tolerance for neutral to slightly acidic pH levels. The research evaluates the structure and diversity of flora in Teleorman County and emphasizes the influence of climate factors such as humidity, temperature, and soil pH on species distribution. Using the transect method and fractal analysis, this study concludes that temperature is the dominant climatic factor shaping local biodiversity. Full article

The paper presents data on the phylogeny, anatomy of vegetative organs, phytocenosis composition, and ploidy of two populations of endemic Allium lehmannianum Merckl. ex-Bunge. in the flora of northeastern Betpakdala. Some discrepancies in nomenclature and sectional affiliation are discussed and corrected. Allium lehmannianum belongs to the section Multicaulea F. O. Khass. and & Yenglal. subgenus Allium, the main range covering the eastern Old Mediterranean region. The ploidy of Allium lehmannianum was studied for the first time using flow cytometry techniques. The sequencing of nrITS was used to construct a phylogenetic tree, including sequences from the NCBI database. The phylogenetic tree of A. lehmannianum was compiled by taking into account previously published data. During the fieldwork in the northeastern part of Betpakdala, the species was found to grow in a rubbly, stony, weakly undulating plain in two different communities. In this work, we applied molecular genetic, cytometric, and anatomical studies on the collected samples of two populations from the northeastern part of the Betpakdala desert to determine the taxonomic composition of a relict and endemic species of Kazakhstan.
