Background

Scapania paludosa var. vogesiaca Müll.Frib. is a type of leafy liverwort, which are non-vascular plants in the division Marchantiophyta. Liverworts are some of the earliest land plants to evolve over 400 million years ago. There are over 7,000 species of liverworts found all around the world.

Morphology and Identification

S. paludosa var. vogesiaca forms small, green leafy mats. The leaves are arranged in two rows and have a distinct folded, keeled shape that’s characteristic of the

Scapania genus. Each leaf has a smaller dorsal lobe and larger ventral lobe. The leaves lack a midrib (costa).
Identifying features of S. paludosa var. vogesiaca include:

• Leaves with pointed tips and small teeth on margins
• Underleaves (amphigastria) absent
• Leaf cells with trigones (corner thickenings)
• Reddish secondary pigmentation sometimes present

Global Distribution and Habitat

S. paludosa var. vogesiaca has a scattered distribution across parts of Europe, including France, Germany, Italy, and Romania. It grows in montane habitats, typically on damp, acidic rocks or peaty soil near streams, waterfalls, and in gorges. The specific epithet “paludosa” means “of marshes”, referring to the moist environments it inhabits.

Ecological Roles and Adaptations

As a poikilohydric plant, S. paludosa var. vogesiaca can tolerate drying out and quickly rehydrate when water is available again. This adaptation allows it to survive in its seasonally wet habitats.

Like other mosses and liverworts, S. paludosa var. vogesiaca

plays important roles in its ecosystems:

• Helps retain moisture and prevent erosion
  

  

• Provides shelter and food for micro-organisms and invertebrates
• Contributes to nutrient cycling and soil formation as it breaks down
  

  

• Acts as a bioindicator of good air and water quality
