blaise commun

Common Kettlewort (<em>Blasia pusilla</em>) is a thallose liverwort in the family Blasiaceae, classified as Least Concern on the IUCN Red List. This primitive non-vascular plant is native to Asia, Europe, and North America, with documented occurrences in Taiwan, five European countries, and the United States. It typically grows on moist, disturbed mineral soils, stream banks, and shaded cliff faces in temperate and cool-temperate regions. As a liverwort, it reproduces both sexually and asexually, with the asexual structures including distinctive flask-shaped receptacles that give rise to gemmae. Common Kettlewort plays a role in early successional plant communities, often colonizing bare or recently disturbed substrates. Its wide distribution across three continents and stable population trends support its Least Concern assessment. Biological traits of this species remain poorly documented in the scientific literature.
