Plant taxonomy underpins biodiversity research and conservation, but global disparities in training and resources hinder progress, especially in biodiversity-rich regions. Through a global survey of taxonomists and trainers, we reveal that 48% of countries have fewer than ten active plant taxonomists and that there are stark regional gaps in access to basic tools and infrastructure. A 'limitations index' highlights Angola, Benin, Botswana, Colombia, Sierra Leone, and Venezuela as facing the greatest challenges. To address these imbalances and build crucial taxonomic capacity, we advocate for inclusive and regionally adapted programs with improved access to infrastructure, engaging teaching methods, cascading mentorship, and stronger collaboration. Strategic investment in plant taxonomy training is essential to realizing the full potential of global plant diversity.
