Caudalejeunea contains around 15 species found in tropical regions worldwide.

Morphology and Identification

C. cristiloba forms small, light green mats on tree bark, leaves, and other surfaces. The shoots are prostrate and irregularly branched, reaching 3-10 mm long. Leaves are incubous (overlapping like shingles), ovate, and 0.4-0.6 mm long with rounded to acute apices. A key identifying feature is the presence of vitta, a central strand of elongated cells. Underleaves are small and bilobed.

Global Distribution and Habitat

This species is widely distributed in tropical regions of Central and South America, Africa, and Asia. It grows in lowland to montane rainforests at elevations up to 1500 m, often in humid microhabitats like stream banks and tree trunks.

Ecological Roles and Adaptations

Like other bryophytes, C. cristiloba plays important ecological roles:

It has adapted to epiphytic life through features like:

  • Small size
  • Rhizoids for attachment
  • Leaves with water-absorbing papillae
  • Tolerance of periodic drying


Caudalejeunea cristiloba may be tiny, but it is a prime example of the incredible diversity and adaptations found in the world of mosses and liverworts. Next time you’re in a tropical forest, take a closer look – you might just spot this little green gem! What other miniature wonders are waiting to be discovered?
