Hi Marvin. The common name for Genlisea is Corkscrew plant. It is most like utricularia in that it has modified underground stems that are used to trap small organisms. The stems extend down into the soil and sometimes water and are in a inverted Y shape. The the two lower sections are twisted like a corkscrew (hence the common name) and lead prey up into the centre of the stem where digestion occurs. There is a great picture of one in Peter D'Amato's book 'The Savage Garden'. I have attached a link to it below. At the moment they are not very common in cultivation and all plants currently known are from tropical regions, specifically Africa and South America. Cheers.
