Introduction
The world of mosses is full of fascinating species, each with their own unique characteristics and ecological roles. One particularly interesting moss is Schlotheimia wainioi Broth., a member of the Orthotrichaceae family. In this blog post, we’ll dive into the details of this captivating bryophyte.
Background
Schlotheimia wainioi Broth., also simply known as

Schlotheimia, is a species of moss belonging to the Bryophyta division and Bryopsida class. It was named after Finnish botanist Edvard August Vainio (1853-1929). The Orthotrichaceae family contains around 900 species worldwide.
Morphology and Identification
Schlotheimia wainioi forms dense tufts or cushions. The stems are erect, usually unbranched, and can reach 1-3 cm tall. The leaves are ovate-lanceolate, 1.5-2.5 mm long, with a short apiculus at the tip. When dry, the leaves become crisped and contorted.
The leaf cells are rounded-quadrate in the upper part and rectangular below. A key identifying feature is the presence of immersed stomata on the capsules. Capsules are

when dry.
Global Distribution and Habitat

Schlotheimia wainioi has a pantropical distribution, found in tropical regions around the world including Central and South America, Africa, and Asia. It typically grows as an epiphyte on tree trunks and branches in moist, shady habitats like rainforests and cloud forests at elevations from 500-3000 meters.
In the table below are some countries/regions where S. wainioi has been recorded:

Ecological Roles and Adaptations
Like many epiphytic mosses, Schlotheimia wainioi plays important roles in its forest ecosystems:
- Provides habitat for micro-organisms
- Helps regulate moisture and humidity
- Contributes to nutrient cycling
- Acts as a pioneer species in forest regeneration
The moss has several adaptations for its epiphytic lifestyle:
- Dense growth form to retain moisture
- Leaves that contort when dry to reduce water loss
- Rhizoids for attachment to bark
- Spore dispersal by wind to reach new tree hosts
Conclusion
Schlotheimia wainioi Broth. is a prime example of the incredible diversity and ecological importance of mosses. From its distinct morphology to its specialized epiphytic habit, this tropical species illustrates the myriad ways bryophytes have evolved to thrive in forest canopies worldwide.
