Leaf surface structures enable the endemic Namib desert grass Stipagrostis sabulicola to irrigate itself with fog water. Journal of the Royal Society Interface, published online 22 February 2012


Description:

Leaf surface structures enable the endemic Namib desert grass Stipagrostis sabulicola to irrigate itself with fog water.

Summary / Notes:

Wetting properties are important for many biological processes as well as for technical applications. A wide variation of wetting effects can be obtained by combining surface chemistry and surface structures. Plant surfaces represent a group of biological surfaces that recently have generated much interest the Lotus effect leading to highly water repellent leaves as an example. The underlying benefits of wetting effects on plant surfaces are manifold ranging from preventing pathogens from settling (as proposed for many waterrepellent leaves), to ensuring the floating ability of aquatic plants or to facilitating the catching of Prey by carnivorous plants. Keywords: contact angle, surface grooves, directional water flow, surface roughness, fog collection, Stipagrostis sabulicola.
