Schlotheimia richardii Besch., commonly known as just Schlotheimia, is a species of moss in the Bryophyta division and Bryopsida class. It was first described by French botanist Émile Bescherelle in 1880. This moss is part of the diverse Orthotrichaceae family which contains over 900 species worldwide.
Morphology and Identification
Schlotheimia richardii forms small tufts or cushions, typically 1-3 cm tall. The leaves are lanceolate in shape, 1.5-2.5 mm long, and have a strong midrib that extends to the leaf tip. The leaf margins are entire (smooth). Capsules are cylindrical and 1.5-2 mm long, borne on a short seta (stalk). The peristome (toothed structure around the capsule mouth) is double, a key identifying feature.
Global Distribution and Habitat
This moss has a pantropical distribution, found in tropical regions around the world including Central and South America, Africa, and Asia. It grows as an epiphyte on tree trunks and branches in humid forests from lowlands to mountains. In the Neotropics, it is often found in montane cloud forests.
Ecological Roles and Adaptations
Like other mosses, Schlotheimia richardii plays important roles in its ecosystem:
- Moisture retention: The dense tufts help trap and retain moisture.
- Microhabitats: It provides shelter for micro-organisms and small invertebrates.
- Nutrient cycling: It aids in breaking down organic matter and cycling nutrients.
The moss has adaptations for its epiphytic lifestyle:
- Rhizoids help it attach to bark
- Leaves overlap to reduce water loss
- Tolerates desiccation by going dormant when dry
