is a small, leafy liverwort with a creeping growth habit. Its leaves are deeply divided into multiple lobes, giving it a distinctive appearance. The lobes are typically 4-6 cells wide and have acute to acuminate apices. The underleaves are also deeply divided and are about half the size of the leaves. Lopholejeunea multilacera can be identified by its unique leaf morphology and the presence of

multicellular, clavate or branched oil bodies in its leaf cells.
Global Distribution and Habitat
Lopholejeunea multilacera has a wide global distribution, found in tropical and subtropical regions across the world. It thrives in moist, shaded environments, often growing on tree trunks, branches, and rocks in forests. This moss is particularly abundant in lowland and montane rainforests, where high humidity and consistent moisture support its growth.
Ecological Roles and Adaptations
Like other mosses, Lopholejeunea multilacera plays essential roles in its ecosystems:
- Water retention: Its dense growth habit allows it to absorb and retain water, helping to regulate moisture levels in its immediate surroundings.
- Nutrient cycling: As Lopholejeunea multilacera decomposes, it releases nutrients back into the soil, supporting the growth of other plants.

- Microhabitats: This moss provides shelter and microhabitats for various small organisms, such as insects, arachnids, and other invertebrates.
Lopholejeunea multilacera has adapted to its moist, shaded habitats through its small size, efficient water absorption, and tolerance to low light conditions. These adaptations enable it to thrive in its specific ecological niches.
