Abstract

It has been reported that Genlisea (see Back Cover) is a plant which specializes in trapping ciliate protozoa, such as Blepharisma, which it has chemotactically attracted, and it was claimed further to be the first such example known (Barthlott et al. 1998). Those authors used both South American (G. aurea, G. violacea) and African (G. margaretae) species for their work, and they found or were able to cite evidence for prey being attracted by means of released chemicals, for the release of digestive enzymes, and the absorption and translocation of radioactive 35S (Barthlott et al. 1998).
