Carnivorous Plant Maniacs in Down Under (2001) In the last part of our Australia trilogy in 2001, we find many carnivorous plants with Kirstie Wulf and Greg Bourke near Sydney and in the Blue Mountains. We look for more sundews and bladderworts with Trevor Hannam in Cairns and film Drosera schizandra in the jungle of Mount Bartle Frere. In Port Douglas, we are invited by Helen and Michael Gabour to the great blues events at the Court House Hotel, dive on the Barrier Reef and encounter more carnivores and an impressive stick insect near Cape Tribulation. In the CP-paradise of the Kimberley near Kununurra, we film many plants and two bug-plant-mutualisms including a sundew with unusual characteristics, which we are delighted to find in cultivation on our return to Germany. We show it to an expert and Dr. Jan Schlauer explains the unique characteristics of the plant in an interview at the end of June. In December 2001, he describes the new species in Carnivorous Plant Newsletter as Drosera hartmeyerorum. This film offers an hour of exciting adventures on the successful search for carnivorous plants in Australia. It doesn't get much more adventurous than this!

Never fear! You do not need a chemistry book to understand this film. Showing a bunch of beautiful sundew species and hybrids, we explain really briefly and clear why particular chemical ingredients of the sundews are not only interesting as cough medicine for homeopathy, but also as traits for taxonomy, in a manner as comprehensible for laypersons as possible. The featured chemical analysis (TLC) is helpful for the description of novel species and gains an additional dimension by the fact that most true species produce only one naphthoquinone or none, while hybrids show the chemistry of both parents combined. That means, if the parents produce different quinones, the hybrid shows both of them and both parents as well as the hybrid can be distinguished chemically that way.
