Soon more ! newDrosera rotundifolia Tentacle-dimorphism.

Drosera rotundifolia Tentakel-Dimorphismus

The Round-leafed Sundew possesses usually straight glue-traps; however, develops temporary also mucus-free snap-tentacles. Even Charles Darwin (1875) reported that tentacles of Drosera rotundifolia are able to bend to the leaf-center in roughly ten seconds. If he measured glue or snap-tentacles has not been mentioned. When and under what conditions they appear has not yet been investigated.

There are different functioning snap-tentacles in the genus. With only 75 milliseconds for a 180° bending the Australian D. glanduligera is the champion. It belongs to the catapult-flypaper traps, which were described for the first time in 2012. Its capture movement is therefore faster than that of the Venus flytrap. These rapid catapults are not able to fix prey. The snap-tentacles of D. burmannii that we call a moderate catapult, bend in approximately ten seconds to the leaf-center. They are able to lift prey from the periphery of the plant onto the sticky lamina and to fix it effectively. Almost all basal rosettes occurring south of the distribution area of D. rotundifolia develop always snap-tentacles. To find out when and under what conditions they occur on the Round-leaved Sundew could certainly be a nice project even for hobby botanists.

Remark: All seedlings of the cold hardy northern sundews possess snap-tentacles in the beginning to capture springtails; however, they lose them during growth.  

newPrey Capture in Milliseconds:
Europe's bladderworts between Lake Constance, Swabian Alb and the Alps.

Utricularia vulgaris Thumb

Bladderworts (Utricularia) possess the fastest capture mechanism of all carnivorous plants. Ultrafast bladder traps suck in prey within less than a millisecond. That is 100 times faster than Venus’s flytrap snap shuts. Seven of the ten species that occur in Europe can be found in the region between Lake Constance, Swabian Alb and the Alps. Thanks to the support of the worldwide recognized CP-expert Dr. Jan Schlauer, we were able to film all seven Utricularia at their natural habitat. The terrific speed of prey captures show recordings with a high-speed camera, taken at the labs of the Plant Biomechanics Group of the Botanical Garden of the Albert-Ludwigs-Universität Freiburg (Germany). Dr. Simon Poppinga kindly provided these remarkable shots. In addition, a scanning electron microscope image featuring the quadrifid glands inside a bladder trap (both published in Poppinga et al. (2016). AoB PLANTS 8: plv140). As the film shows, their shape can be helpful for the determination of several quite similar looking species. Detailed information on our domestic bladderworts is provided by the scientific article “Die Gattung Utricularia in Bayern” (2014) published by the Bavarian Botanical Society, from which we quoted repeatedly in this film. To protect the partly endangered plants, but also because the access to some of the swamp areas without an experienced guide is not at all harmless, we do explicitly not mention exact locations.

newBehaviour of T2- snap-tentacles in moderate and rapid catapult-flypaper traps.

T2-snap-tentacles

Demo-Trailer on catapulting tentacles in Drosera section
Bryastrum, Coelophylla and Thelocalyx.

Moderate catapult-flypaper traps like D. sessilifolia, D. burmannii or the larger pygmy Drosera possess T2-snap-tentacles that function repeatedly.  In contrast to the one-shot T3-snap-tentacles of D. glanduligera they show a much longer reaction time and the bending stops at approximately 90-120° if no prey has been captured and actuats further receptor potentials. This behaviour can be compared with the "narrowing" movement of Dionaea flaps.

This trailer shows reaction times (waiting may be boring for some people) and the different bending behavour of T2-snap-tentacles, which act in fractions of a second in some pygmy Drosera.
Schule trifft Wissenschaft (School meets Science).
Die Preisverleihung der Robert Bosch Stiftung 2009 in Berlin.


Schule trifft Wissenschaft

On behalf of Prof. Dr. Rainer Hedrich from the Julius-von-Sachs-Institute of the University Würzburg, we filmed the award ceremony of “Schule trifft Wissenschaft” (School meets science) conducted by the German Robert Bosch Stiftung (foundation) under the patronage of the former minister of education and research Prof. Dr. Annette Schawan, who sent a video message. Laudators were the co-inventor of the MP3-player Prof. Dr. Karlheinz Brandenburg for one 2nd prize, the German astronaut Prof. Dr. Ernst Messerschmid for the second 2nd price, and Nobel Prize winner Prof. Dr. Erwin Neher for the main prize. One of the 2nd prizes awarded the “Project Phytosensors”. The young researchers investigated (beside others) the sense of taste of the Venus flytrap. Before the event, Prof. Hedrich invited us to hold a lecture on rapid tentacle movement (snap-tentacles) for students and teachers of the Friedrich-König-Gymnasiums in the frame of that project. Our lecture is online on YouTube as playlist:  https://www.youtube.com/watch?v=4ocyt_EkR84&list=PLhZbrINQjLLNZ1xQcgcRiAj2rBSWjBoha.


Based on our technical papers on the Sundew family and many years of experience in filming, Prof. Hedrich asked us to document the award ceremony in Berlin on video including the editing and we received the copyright for this production. In the run-up, the students did only know that they are nominated; however, not that they actually awarded such a great prize. From ten Germany wide nominated projects received the main prize (€ 50,000,-): The Heidelberger Life-Sciences Lab am Deutschen Krebsforschungszentrum Heidelberg. Two 2nd prizes (each € 20'000) awarded: The „SaarLab und die Sieben-Labore-Tour“ at the Universität des Saarlandes and
„Phytosensorik“ at the Friedrich-Koenig-Gymnasium Würzburg

The „Project Phytosensors“ and the candidates of the Friedrich-König-Gymnasium are in our focus; however,  we show also the other winners and their prominent laudators. Presenter of the event was Germany’s famous TV-moderator Sven Voss. Please find further information on our website: http://www.hartmeyer.de/Schule_trifft_Wissen_1.html.
Symbiotic bugs living on carnivorous plants in tropical Australia HD Zeichen

Symbiotic bugs YouTube

Predatory mirid bugs form biological communities with different sticky carnivorous plants. Such a symbiosis with Roridula and Pameridea bugs was first described from South Africa by the German botanist Rudolf Marloth in 1902. About half a century later, Lloyd (1942) and China (1953) reported on Setocoris and Cyrtopeltis bugs living on Byblis gigantea and some Drosera near Perth (Southwest Australia). In 1995, Irmgard and I were very fortunate to film and publish four of such mutualisms for the first time on tropical Byblis and Drosera in Northern Australia. On three journeys, we spent more than six months in Australia to capture news on carnivorous plants on film and found luckily even a not described sundew. As a positive consequence, our movies and articles on the discoveries found the interest of acknowledged scientists, and led to an invitation to hold a video lecture at the National Science Museum in Tokyo, Japan. That was both, a great honor and a confirmation of the relevance of our work. This film contains excerpts from our original footage and comments; however, remastered (includes English subtitles) as a brief entertaining (HD) summary on the bug - carnivorous plant mutualisms in tropical Australia.
Laser fire on Drosera hartmeyerorum  HD Zeichen
ICPS World Conference Tokyo 2002

Our experiments suggest that the yellow emergences of Drosera hartmeyerorum act like a residual light amplifier, comparable to the eyes of crocodiles or cats when illuminated with a torch at night. The film provides our experiments with different light sources like halogen and red laser.

CAUTION: Laser beams are dangerous. Protect your eyes  when you conduct such tests, especially when you observe the laser through a magnifier.

REMARK: We received on YouTube, Facebook and e-mail the same question: What benefit has the plant from these emergences ? Well, the incident sunlight is white and the reflected light is (flickering due to movement in the wind) bright yellow. That is very attractive to insects, especially on a strong contrasting dark red background, which appears black to insects. Yellow flypapers are very effective and often used to trap flying pests in nurseries and on fruit trees. The dark red background appears black to insects because their visual ability is shifted to the short-waved range of the spectrum. They don't see red, but they are able to see UV patterns. Regarding these facts, the emergences, which developed from simple sticky tentacles, are perfectly designed to lure prey into the sticky plant center.

Our article in CPN 44/4 (2015):
Several pygmy Sundew species possess catapult-flypaper traps with repetitive function, indicating a possible evolutionary change into aquatic snap traps similar to Aldrovanda. Siegfried R. H. Hartmeyer and Irmgard Hartmeyer (PDF)


Catapults in Pygmyland


Amazing results: Pygmy sundews capture minute prey like springtails with rapid catapult action. Our experiments for this film (English subtitles) show that Drosera glanduligera is not longer the only sundew with a catapult-flypaper trapping mechanism. Also the snap-tentacles of several pygmy Drosera act with the speed of a closing Venus flytrap and fling walking prey from the periphery of the plant onto its sticky leaf. Therefore they turn out to be actually comparable with the amazing Drosera glanduligera, however, their catapults are multifunctional and possess a mechanism to avoid unessential movement: Like the Venus Flytrap. Under our microscope we examined 22 Drosera and received surprising results.

Furthermore we were able to film many pygmy Drosera in situ on field trips with Allen Lowrie, Greg Bourke and Kirstie Wulf (1991 & 2001), providing these shots now for the first time on YouTube.

We are happy to introduce Gideon Lim from Malaysia, who showed the first video of the rapid snap-tentacles of D. pygmaea "New Zealand, all green" on the internet even in 2014.

Fluorescent Pitcher Plants YouTube

Many carnivorous plants with pitfall traps show a bluish fluorescence under UV-light. In Sarracenia it is most likely the toxin of the Poison Hemlock: coniine. The fluorescent agent in Brocchinia and Nepenthes is unknown. Whatever relevant the effect is for successful prey capture, it is impressive to experience it in the greenhouse. Special thanks go to Richard Bayerl (Stuttgart, Germany), who provided his UV-lamp and participated personally in the experiments.

Feed me ! Füttere mich ! (Logo)

A sundew is kicking a fruit fly with one of its catapulting tentacles and makes it stumble into the catapult-trap of a neighbour plant. A mighty fine draft for this filmlet. The scientific publication of the catapult-flypaper trap in 2012 in PLOS ONE (http://dx.plos.org/10.1371/journal.pone.0045735) has been a botanical sensation. Also the technology writer Volker Arzt became aware of it and recommended our (until now unique) HD-shots to the editorial staff of the scientific broadcast "planet wissen".

The result: On September 11th our shots will be on air for the first time worldwide on the German TV stations SWR (1:15 pm) and ARD alpha (3 pm).

Amorphophallus konjak mit A. Günzschel



Visit of the "Weiler Zeitung", which printed an article on the flower. Reporter Mrs. Günzschel did bear the "fragrance" bravely ;-).  

To experience this amazing visual illusion, pause the film and place your favourite living plant beside your screen. Continue the film and - sitting close to your screen - look into the center of the spinning helix (takes 20 seconds). When the helix ends, look at your plant beside the screen (or without any plant look at the photo following the helix): you see everything rapidly growing! Be surprised !

WARNING: Don't view this if you tend to get dizzy or to feel sick! Also too much repetition may cause giddiness even for healthy persons.

Fleischfresser auf dem Blocksberg HD Zeichen
(German language)

Fleischfresser auf dem Blocksberg

In Goethe's "Faust" can be read, that witches meet on top of the legendary mountain "Brocken" (Germany, vernacular: Blocksberg) to sweep off the last snow before May. The area is now part of the National Park (NP) Harz, and also some species of carnivorous plants occur there. We received a filming permit by the NP authorities and we express our gratitude to Dr. Gunter Karste, who accompanied our film-tour into the secret mountain bogs.

The film starts in the climatic spa Benneckenstein, including a short retrospect on the history of the Hartmeyer family, who lived here until their family enterprise has been unlawfully dispossessed by the communistic authorities of the former German Democratic Republic (GDR - Remark: After the German reunification it became family property again.). The Hartmeyers escaped to the western part of Germany in the 1950s, but the contact with relatives and old friends remained constant in time.

A special thank goes to the Benneckenstein chronicler Jürgen Kohlrausch, who supported this film project from the beginning and who showed us some Drosera that grow not far away from Siggi's old native city in an area which is now called the "Green Belt". It sounds amazing, but where the former German zonal border existed with its strips of death and mine-fields, many endangered animal and plant species survived. Apart from urban sprawl and roadmaking, they found interestingly here a secure refugium.

Wide fields of large Brocchinia hechtioides cover the slopes of Cerro Aracamuni and beautiful flowering Utricularia compete with wonderful orchids. But suddenly, on the way to the famous Heliamphora tatei site, happened an accident with a machete. The hit leg of a crew member must be needled immediately without any doctor because the helicopter arrives not before two more days. Finally the guys are really tough enough to stand also this challenge, even though they were isolated in the wild.

With this episode the uploads from our DVD "On CP-Tour with Stewart McPherson" are complete. Therefore we provide - and recommend to view - these adventures now also in a playlist, containing all trips in the orginal order of the DVD (see below).

Different from first conclusions in the mid 2000s, meanwhile a dispersal of seeds by birds is discussed to be most likely for that odd appearance. Stewart McPherson also encounters a large scorpion (Brotheas species) and is able to film the beautiful Heliamphora neblinae in an amazing ambiance.

This short film features the prey-catching by the catapult-flypaper-trap of Drosera glanduligera. Simon Poppinga from the Plant Biomechanics Group of the Botanic Garden of the University Freiburg (Head Prof. Dr. Thomas Speck) operated the high-speed camera and the scanning electron microscope. The HD-shots were made by Irmgard and myself on our living-room table, using our Sony Z5 camera. This digest shows explicitly the prey-catching of the catapult-flypaper-trap and was new edited for those, who like to see just the basal principles, and not the complete documentation on our examinations. Our collaboration with the Plant Biomechanics Group was published on September 26 2012 at PLOS ONE (see right side).

(The Diva's Catapult)
HD Zeichen




We show the first experimental evidence for the role of catapulting tentacles in prey capture of a carnivorous plant and introduce a new active trapping mechanism: The catapult-flypaper-trap. This video documents our (Irmgard and
Siegfried R. H. Hartmeyer) collaboration with the Plant Biomechanics Group of the Botanic Garden of the Albert-Ludwigs-University Freiburg (Germany) in 2012, providing all necessary information to handle the sophisticated cultivation of Drosera glanduligera and to understand how this unique sundew from southern Australia uses its amazing combined catapult-flypaper trapping mechanism. Prey animals walking near the edge of the sundew trigger a touch-sensitive snap-tentacle which swiftly catapults them upside down onto adjacent sticky glue-tentacles. By acting like a band-conveyor, the glue-tentacles lift the prey into the concave leaf-center within two minutes where digestion takes place, well protected from kleptoparasites. This is the first detailed documentation and analysis of the prey-catching, functional morphology, and kinematics of such catapulting tentacles. The result depicts a unique and surprisingly complex mechanical adaptation to carnivory.
This report is available on DVD and on Blu-ray (HD).

To recover from our CP-trip to Alabama and Northern Florida with Brian Barnes, we return to Lake Mary, at the outskirts of Orlando. On visits at Brian's home, he shows us his wonderful CP-collection, containing i.e. the selfmade cultivars Drosera 'Ambrosia' and Drosera 'Dreamsickle" (hybrids of different D. filiformis forms), as well as some of the most beautiful Heliamphora that we have ever seen in cultivation. One evening Brian proofs to be a smokin' guitar player, performing a jam session with his friend Tony Tresca (bass) and his wife Cherry (drums), from which we included a short excerpt. Finally Brian guides us to the nearby Long Pine Preserve, to film the beautiful Sarracenia minor. Due to an unusual drought, many plants are suffering and we could not find Pinguicula lutea and Pinguicula caerulea anymore. Only one year ago Brian documented several of these, now simply dried up Butterworts. Such unusual droughts are in many parts of the world on the rise and probably caused by global warming, which therefore becomes an additional threat for the endangered genus Sarracenia.

From Splinter Hill Bog in Alabama we head on south to Carrabelle in Florida and continue to film carnivorous plants. Our base is the recommendable snuggish little "Old Carrabelle Hotel". From here its just a daytrip to the famous growing-sites around Sumatra and Tate's Hell, where we are able to film i.e. the wonderful Sarracenia flava var. rubricorpora. This red form is seriously endangered by poaching and, as Brian reports, the number of plants is declining from year to year. Not far away we are able to film a site with large Pinguicula planifolia "giant". In Tate's hell we stumble across Drosera brevifolia and are shaken to the score to see the very sad results of heavy poaching with our own eyes. As Brian reports from his own observations, the beautiful pink form of Sarracenia leucophylla at Tate's Hell has been poached since years for use in the floral industries, and today only very small remnants survived, which will probably soon disappear from their natural habitat if the poaching does not end.

The movement is caused by pulvini, cell-structures which are also known from other plant families like Mimosa and beans. Amazingly this has never been mentioned in literature before.

The ICPS World Conference in Tokio 2002

In 2001 we received an invitation by Prof. Katsuhiko Kondo (Hiroshima) to join the ICPS World Conferenc in Tokyo (Japan) to give a lecture on our CP-tours in Australia, and to produce the official conference-video with our equipment. The 16 movies above provide most of the lectures of many prominent CP-experts, held at the event in 2002. Additional information can be found with our article "Die 4. Internationale Karnivorenkonferenz in Tokio" for "Das Taublatt", the journal of the German CPS "GFP"

Triphyophyllum peltatum

Triphyophyllum peltatum

Thanks to unique video shots from Sierra Leone (Africa) by Stewart McPherson and photos from a successful examination at the university of Würzburg (Germany) by Dr. Jan Schlauer & Dr. Heiko Rischer we were able to edit this film featuring the complete life cycle of the clandestine growing carnivorous liana Triphyophyllum peltatum. The film is an excerpt from our DVD "Triple E meets Triphyophyllum".

Sophisticated survival strategies

Sophisticated survival strategies
of the annual Drosera


The anual Drosera species develop the most sophisticated trapping mechanisms in the genus, to catch enough protein for a complete life-cycle within a single season.

Remark: This footage awarded a 2nd price in the ChloroFilms Plant Biology Contest in 2010. The contest is organised by the Pennsylvania State University and supported by YouTube.

A visit at Borneo Exotics in Sri Lanka

In 2004 we visited Robert Cantley's world famous Nepenthes nursery in Sri Lanka. The film shows the professional and environment-friendly propagation of the endangered pitcher plants at Robert Cantley's greenhouses. No plants are collected in nature, everything is produced with tissue culture, which is an important contribution to keep even such species world-wide alive in culture, which are seriously endangered in their natural habitat. We are happy to show unique pictures of wonderful and rare plants. On December 26 we experience the big 2004-tsunami without damage, because our hotel at the sea-side in Mount Lavinia was built on a 3-4 meters high rock, fortunately just high enough ...

The ant massacre


The ant massacre




In the early 1990s, ants start their mating flights through the floor of our  tropical greenhouse. That becomes a big meal for our pitcher plant hybrid Sarracenia x catesbaei.

Filming in Australia (1995 & 2001)

2001 we return to Australia for filming. Invited by Michael Gabour, owner of the Court House Hotel (Port Douglas), we are even able to record a wonderful Blues-soundtrack for our DVD. Thanks to Kirstie Wulf, Greg Bourke and Trevor Hannam we are able to provide numerous CP-sites and great adventures.

Stylidium


Triggerplants (Stylidium)




The rapid moving flowers of this mainly Western Australian genus are very interesting. Stylidium is growing frequently in the same habitats as CP.
Sarracenia alata

Sarracenia alata

Enjoy a field with beautiful pitcher plants near DeSoto (Mississippi, USA). We edited this movie from videos, taken by the famous author of CP-books, Stewart McPherson. The film was produced with hiskind permission.

Drosera snap-tentacles

In 2005 we published (DAS TAUBLATT) and documented on film the thrilling ability of Drosera glanduligera to retract its unique marginal tentacles in fractions of a second, which is about as rapid as the Venus Flytrap snap-shuts. In 2007 followed our movie "Drosera: Snap-Tentacles and Runway Lights", describing in detail also other, quite different tentacles in the genus Drosera (an upgraded article has been published in 2010 in Carnivorous Plant Newsletter).
