The Catkin Yew (Amentotaxus argotaenia) is a species in the genus Amentotaxus. It is currently classified as Near Threatened on the IUCN Red List. Typically found in temperate and boreal forests, often at higher elevations.

Compressed Flapwort

<em>Nardia compressa</em>, commonly called the Compressed Flapwort, is a leafy liverwort in the family Jungermanniaceae, a lineage of non-vascular land plants (division Marchantiophyta) that diverged from other embryophytes over 400 million years ago. This small, mat-forming bryophyte typically colonizes moist, acidic substrates along stream banks, seepages, and wet rock faces in cool-temperate habitats throughout Europe. Its flattened, overlapping leaves give the plant a compressed appearance, which inspired both its common and scientific names. Like all liverworts, <em>Nardia compressa</em> lacks true vascular tissue and absorbs water and nutrients directly through its leaf surfaces, deriving energy through photosynthesis rather than heterotrophic feeding. The species has been recorded in Belgium, Norway, and Sweden, suggesting an affinity for the moist, boreal and Atlantic climatic zones of northwestern and northern Europe. It is currently assessed as Least Concern by the IUCN, indicating no immediate extinction risk across its known range. Biological traits including individual lifespan, reproductive rates, and specific growth measurements remain poorly documented relative to vascular plant species, though liverworts are generally slow-growing perennial organisms tightly dependent on stable moisture regimes.
