Ectohydric mosses (a) rely mainly on water transport along the external surface of the plant by capillarity. The spaces between the leaves and stem and between papillae on the surface of leaves seem to be optimised to act as capillary channels to draw water up and down the plant. The rhizoids may form a dense felt-like tomentum and small leaf ... WebEctohydric mosses are known accumulators of atmospheric heavy metals. Reliable bioindication of atmospheric heavy metals in the Southern Appalachians using moss has been limited by poor species distribution in moss used in analogous studies.
