What specific leaf feature of Espeletia species acts like a sponge to absorb moisture from the air?

Answer

Dense layer of trichomes

The key structural adaptation enabling the frailejón's water collection ability is the physical nature of its leaves. These leaves are covered in a thick, velvety, and hairy layer. This dense covering is composed of trichomes, which function physically like a sponge, efficiently absorbing moisture directly from the frequent mist and high humidity characteristic of the páramo environment. This absorbed water is then channeled down to the roots, contributing directly to soil moisture regulation.
