Integrative Taxonomy of Vascular Plant Species
Summary
Integrative taxonomy has emerged as a cornerstone of modern plant systematics by combining multiple independent lines of evidence—including molecular markers, morphology, cytogenetics and ecological data—to delimit and describe species of vascular plants. This holistic framework addresses long-standing challenges posed by phenotypic plasticity, cryptic diversity and convergent evolution, offering more robust hypotheses of species boundaries than traditional morphology-only approaches. By synthesising DNA sequence data, karyological profiles, morphometric analyses and habitat niche information, integrative studies can resolve complex species complexes, uncover previously unrecognised lineages and identify evolutionarily significant units that merit targeted conservation. The global significance of this approach extends from refining biodiversity assessments and informing conservation priorities to underpinning ecological restoration, bioresource management and biogeographical research. Practical applications include guiding protected-area design, supporting legal recognition of rare taxa and enhancing the reliability of ecological and biogeographical databases used in predictive modelling under environmental change.

Technical terms
Integrative taxonomy: An approach that combines molecular, morphological, cytogenetic and ecological data to delimit species and infer their evolutionary relationships.
Phylogenetic inference: The reconstruction of evolutionary relationships among taxa using genetic sequence data.
Morphometry: The quantitative measurement and analysis of shape and size variation in organisms.
Karyology: The study of chromosome number and structure to inform taxonomic and evolutionary hypotheses.
Single nucleotide polymorphism (SNP): A point mutation at a single nucleotide position in the genome, often used as a high-resolution genetic marker.
