Scientists Warn 21.2% of Flowering Plant History Faces Extinction as 9,945 Species Qualify as EDGE
2 articles · Updated · ScienceAlert · Jul 19
Summary
21.2% of flowering plants’ evolutionary history is at risk of extinction, according to a Science study that applies the EDGE method to angiosperms for the first time.
335,497 known flowering plant species were assessed, and 9,945—about 3% of the total—were identified as both evolutionarily distinct and globally endangered.
Human pressures are driving that risk, with researchers warning the losses could erase irreplaceable branches of the tree of life and potential future sources of food, medicines and ecosystem resilience.
Vanilla planifolia, the corpse flower and the world’s smallest water lily are among the threatened species highlighted, alongside little-known plants such as the jellyfish tree and Hondurodendron urceolatum.
The authors say the ranking can help direct scarce conservation resources as more than two in five plants are already estimated to face extinction risk.

Unprecedented Threat to EDGE Flowering Plants: Extinction Risks, Causes, and Conservation Solutions
Overview
A landmark study published in May 2026 warns of an unprecedented extinction risk for flowering plants worldwide. Focusing on EDGE species—those that are both evolutionarily unique and globally endangered—the research cross-referenced these plants with the Flora of the World database. The findings are alarming: four EDGE species are now classified as 'Extinct in the Wild' by the IUCN, highlighting a severe loss of biodiversity and ecological function. Notably, while early American botanists saved Franklinia alatamaha through seed collection and propagation, other unique plants like angel’s trumpets have vanished from their natural habitats, underscoring the urgent need for conservation action.
