Introduction
Mosses are often overlooked, but they play crucial roles in ecosystems around the world. One particularly fascinating species is Daltonia forsythii Broth. ex Cardot, a small but mighty moss in the Daltoniaceae family. In this blog post, we’ll dive into the details of this delightful little plant.
Background on Daltonia Mosses
The genus Daltonia contains around 35 species of mosses found in tropical and subtropical regions worldwide. They are characterized by their small size, creeping growth habit, and capsules that are held at an angle on the seta (stalk). Daltonia forsythii is one of the more widely distributed species.
Morphology and Identification
D. forsythii forms dense mats of tiny green leaves. The individual plants are only 2-10 mm tall. The leaves are ovate to lanceolate and have a strong midrib that extends to the leaf tip. Capsules are ovoid and held at a 45° angle. With a hand lens, you can see the peristome teeth around the capsule mouth.

Global Distribution and Habitat
This moss has a wide distribution across the tropics, found in Central and South America, Africa, and Asia. It grows as an epiphyte on tree trunks and branches in moist forests from lowlands to 2000 m elevation. It prefers partial shade but can tolerate some sun if humidity is high.

Ecological Roles and Adaptations
Like other mosses, D. forsythii plays important roles in its ecosystem:
- Captures and retains moisture

- Provides habitat for micro-organisms
- Prevents soil erosion
- Pioneers on bare substrates
Its small size and mat growth form help it resist desiccation. The angled capsules may aid in spore dispersal by wind.
