Vesicularia dubyana
Singapore Moss, Java Moss
A delicate, creeping moss native to the humid riverbanks and shaded streambeds of tropical Asia. It spreads across rocks, wood, and substrate by attaching with fine rhizoids, forming layered bright-green mats of tiny, lance-shaped leaves. In a closed terrarium it thrives in steady moisture and low light — conditions that closely match its understory habitat. It also grows fully submerged, making it equally at home in paludariums and aquascapes.

Care
Prefers very high humidity, low light, with 15–30 °C, and reaches 5 cm at maturity.
