Background on Barbula Moss

Barbula is a genus of mosses found all around the world. They are part of the Bryophyta division and Bryopsida class. There are over 200 Barbula species. Barbula mosses tend to grow in small, dense cushions on soil, rocks, and tree bark.

Morphology and Identification

B. somaliae forms short turfs of green to yellow-green. The leaves are lance-shaped and have a strong midrib that extends to the leaf tip. Leaf margins are rolled inward when dry. The spore capsules are cylindrical and borne on short stalks. Look for the characteristic peristome teeth that twist when dry to aid in spore dispersal.

Global Distribution and Habitat

This species is found in Africa, Asia, and the Americas. It grows in dry, exposed habitats like rocky outcrops, sand dunes, and disturbed soils. In Somalia, it’s one of the few mosses able to survive the harsh conditions.

Ecological Roles and Adaptations

Like other mosses, B. somaliae plays vital roles in its ecosystems:

  • Helps retain moisture and prevent soil erosion
  • Provides shelter and food for micro-organisms and insects
  • Pioneers the growth of other vegetation

To thrive in arid environments, B. somaliae has some nifty adaptations:

  • Leaves curl up when dry to reduce water loss
  • Rhizoids anchor the moss and absorb moisture from the soil
  • Spores are dispersed by wind to colonize new areas


Who knew such a small, unassuming plant could be so intriguing? Barbula somaliae Müll.Hal. is a perfect example of how mosses are superbly adapted to their environments and play crucial ecological roles.
