Re: [Aroid-l] lotus effect with Colocasia fallax

Hi Ted,
Pistia is in fact a very beautiful example for a water-repellent surface. It has to be kept in mind - as you mention - that it generates this superhydrophobic effect with hairs (not with papillate cells like in Nelumbo or Colocasia) that are covered with wax. So, the term 'lotus-effect' describes the syndrom of superhydrophobicity (which means that the contact angle of a water droplet is at least 150°), but there are different structures within the Araceae and other plant families, that produce this effect.
