Dendroceros africanus Steph. is a thallose liverwort, meaning it grows in a flat, ribbon-like form rather than the typical upright stems of most mosses. This distinctive growth habit is one of the defining features of the Anthocerotopsida

class, to which Dendroceros belongs.
Main Content
Morphology and Identification
Dendroceros africanus Steph. is a striking moss, with its dark green to blackish-green thalli that can reach up to 10 centimeters in length. The thalli are irregularly branched and have a distinct midrib running along their length. One of the most remarkable features of this moss is its ability to produce sporophytes

that can reach an impressive height of up to 10 centimeters, making them among the tallest structures produced by any bryophyte.
Global Distribution and Habitat
Dendroceros africanus Steph. is widely distributed across tropical and subtropical regions of Africa, Asia, and the Americas. It thrives in moist, shaded environments, often found growing on soil, rocks, or decaying wood in forests, ravines, and along streams.
Ecological Roles and Adaptations
Like many bryophytes, Dendroceros africanus Steph. plays a crucial role in its ecosystem. It helps to retain moisture and prevent soil erosion, creating a suitable microhabitat for other organisms to thrive. Additionally, this moss is known for its ability to tolerate desiccation, a remarkable adaptation that allows it to survive periods of drought by entering a dormant state and reviving when moisture returns.
Case Studies/Examples
In a recent study conducted in the Kakamega Forest of western Kenya, researchers found that Dendroceros africanus Steph. was one of the most abundant and diverse bryophyte species present. This highlights the importance of this moss in maintaining the biodiversity and ecological balance of tropical forest ecosystems.
