collared notchwort

The Collared Notchwort, known scientifically as <em>Mesoptychia collaris</em>, is a liverwort belonging to the family Jungermanniaceae within the class Jungermanniopsida. <em>Mesoptychia collaris</em> is a bryophyte — a non-vascular land plant — and represents one of the leafy liverworts, characterised by flattened, leaf-like structures arranged along creeping stems. This species is associated with moist, shaded habitats typical of temperate regions, including areas of Europe and North America. It is reported to occur in Norway, Sweden, and the United States. Like other liverworts, <em>Mesoptychia collaris</em> plays a role in moisture retention and habitat structure in the ecosystems it inhabits. Detailed biological traits including typical lifespan measures and physical dimensions are poorly documented for this species in available literature. The Collared Notchwort is currently assessed as Least Concern on the IUCN Red List.
