Paths and obstacles to an evidence-based, reproducible, and dynamic Plant Taxonomy

Abstract

Plant taxonomy, though historically foundational in the biological sciences, has been slow to incorporate modern standards of scientific rigor. Traditional reliance on morphology and purely descriptive practices, with limited use of statistical and phylogenetic analysis, has resulted in low reproducibility and limited scientific robustness. This essay advocates for a shift toward an evidence-based and reproducible plant taxonomy, aligning plant systematics practices with contemporary principles of open science. For such an endeavor, it is highly recommended to adopt integrative and analytical approaches to taxa delimitation. In such an approach, taxa are not factual data, but rather conclusions drawn from analysis. Practical recommendations are offered to guide journals, researchers, and institutions toward a more robust and scientifically credible taxonomic practice.
