Background on Radula Mosses
Radula is a genus of leafy liverwort mosses in the Radulaceae family. There are over 200 species of Radula found worldwide. They are classified in the division Marchantiophyta and class Jungermanniopsida. Radula mosses are unique in having a specialized lobule (leaf lobe) that aids in water retention.
Morphology and Identification of Radula sumatrana Steph.
Radula sumatrana Steph. is a small moss, typically growing in dense mats. Its leaves are arranged in two rows and have a distinct

incubous insertion, meaning the upper leaf lobe overlaps the lower lobe of the leaf above it. The leaf cells are hexagonal to quadrate in shape. R. sumatrana is dioicous, with separate male and female plants.

Global Distribution and Habitat
Radula sumatrana is found in tropical and subtropical regions of Asia, including Indonesia, Malaysia, and the Philippines. It typically grows on tree trunks, branches, and occasionally on rocks in humid forests at elevations from sea level to 2000 meters.
Ecological Roles and Adaptations
Like other mosses, R. sumatrana

plays important roles in its ecosystem:
Moisture retention: Its mat-like growth and lobules help trap and retain water, preventing erosion and maintaining humidity.
Microhabitats: It provides shelter and microhabitats for various invertebrates and microorganisms.
Nutrient cycling: As it grows and decomposes, R. sumatrana aids in nutrient cycling in the forest ecosystem.
