Leaf arrangement collects water: epiphytes

Loading...

The leaves of many collospermum epiphytes are arranged in a fan-like shape that aids in catching water. This is the Collospermum hastatum. / Jon Sullivan / LicenseCC-by-nc - Attribution Non-commercial

Leaves of Collospermum epiphytes capture water due to their fan-shaped arrangement.

BIOMIMICRY TAXONOMY
Summary
"Collospermums are more specialized as epiphytes…The form of the nests is similar to those of the astelias, but the leaves are different. They are broadly rounded at the base and arranged in wide fans with enclosed spaces between them that function as water tanks…Roots grow upward into the tanks to absorb water, and it has been suggested that scales on the inner leaf surfaces may also absorb water after the fashion of the bromeliads, but this has not been proved." (Dawson and Lucas 2005:39-41)

I don't know this for sure, but the minute hairs along the stems of new england wineberries catch the morning fog, I am sure to help with providing the extra moisture they need / and or to keep their environment humid.
