Background
Breutelia kinabaluensis Dixon is a type of moss that was first described by the British bryologist Hugh Neville Dixon in 1935. It is named after Mount Kinabalu in Malaysia, where it was originally discovered. This moss belongs to the genus Breutelia and the family Bartramiaceae, which contains over 400 species worldwide.
Morphology and Identification
B. kinabaluensis is a relatively large moss, with stems that can reach up to 10 cm in length. The leaves are lanceolate (lance-shaped) and have a distinct midrib. They are arranged in a spiral pattern around the stem and are often twisted when dry. The leaf margins are serrated, and the cells are elongated.
The sporophytes (spore-producing structures) of B. kinabaluensis are cylindrical capsules that are held upright on long setae (stalks). The peristome (toothed ring around the capsule mouth) is double, with an outer layer of 16 teeth and an inner layer of 16 segments.
Global Distribution and Habitat
B. kinabaluensis is primarily found in Southeast Asia, with records from Malaysia, Indonesia, and the Philippines. It typically grows on moist, shaded rocks or tree trunks in montane forests at elevations between 1000-3000 meters. This moss prefers humid environments with high rainfall and moderate temperatures.
Ecological Roles and Adaptations
Like other mosses, B. kinabaluensis plays important ecological roles in its habitat. It helps to retain moisture, prevent soil erosion, and provide shelter for small invertebrates. This moss has adapted to its montane environment by developing thick cell walls and water-holding structures in its leaves to withstand desiccation during dry periods.

Conclusion
Breutelia kinabaluensis Dixon is a prime example of the incredible diversity and adaptability of mosses. From its unique morphology to its specialized habitat preferences, this species showcases the wonders of the bryophyte world. As we continue to study and appreciate these often-overlooked plants, we can gain a deeper understanding of the complex ecosystems they support. So the next time you’re hiking through a montane forest in Southeast Asia, keep an eye out for the twisted leaves and upright capsules of B. kinabaluensis—you might just be looking at one of nature’s hidden gems!
