The one that lives in the shadow of the sphagnum has stems that are creeping and branching, forming small, leafy mats that grow among the sphagnum cushions. The leaves are small and rounded, with a distinct, toothed margin, odontoschisma means toothed split. The colour is pale green to reddish-brown, often blending in with the surrounding sphagnum. It is the liverwort of the bog companion, the one that lives quietly among the sphagnum's empire, the one that asks for nothing but a little damp ground. What makes it special is the companionship. Odontoschisma liverwort is a specialist of bog habitats, growing almost exclusively among sphagnum moss. It does not compete with the sphagnum. It lives alongside it, creeping through the sphagnum cushions, finding its niche in the wet, acidic environment. It is the liverwort of the quiet neighbour, the one that lives in the shadow of the sphagnum empire, the one that has learned that cooperation is better than competition. The leaves are small and rounded, with a toothed margin, a subtle detail that requires a hand lens to see. The leaves are arranged in two rows along the stem, overlapping like the scales of a fish. Under a hand lens, the teeth are visible, tiny points along the edge of the leaf, a miniature saw blade. Biologically, the odontoschisma liverwort reproduces by spores, released from capsules on short stalks. It also reproduces asexually via gemmae. The gemmae break off and grow into new plants, allowing the liverwort to spread through the sphagnum cushions. To find odontoschisma liverwort is to look among the sphagnum cushions in the bog. There it is, a small, pale green to reddish-brown, leafy mat, creeping quietly through the sphagnum. It is the liverwort of the quiet companion, the one that lives in the shadow of the sphagnum empire, the one that proves that the most successful organisms are not always the loudest.
