Much like Jack was astonished by the plant that germinated in the fairytale, I was completely intrigued that a bean could grow such a marvelous plant. Charles Darwin was enthralled as well; it was included in one of his last books, The Power of Movement in Plants. It seems that many people are more hopeful optimists rather than bringing up supporting evidence and solid facts. Image of Codariocalyx motorius (dancing plant) courtesy of Wikimedia Commons. Image constructed on Molview by author. Watch the first minute of this clip to see the dancing plant in action! Desmodium gyrans, now Codariocalyx motorius - the telegraph plant - is a tropical Asian shrub, one of a few plants capable of rapid movement, like Mimosa pudica and the venus flytrap. Its common name is Dancing Grass or Telegraph Plant or Semaphore Plant-- after the leaf movements, which resemble semaphore signals. I first came across it in preparation for a plant chemical ecology class. Lev-Yadun, Simcha. Seismonasty is a contractile movement probably caused by the contractions of cytoplasmic protein. This indicates, to some, that these plants have memory of non-disruptive stimulus in their environment such as a venus fly trap not reacting to raindrops and Mimosa plant not reacting to constant stimulus.“Plants have electrical and chemical signalling systems, may possess memory, and exhibit brainy behavior in the absence of brains.” (The Intelligent Plant). Mitsch, Jacques. The pulvinus is the area between the leaflet and the midrib/rhachis (. Some other common names include the The leaves of this plant consist of three leaflets (pinna) of which the two lateral ones move in a continuously and jerkily fashion. 7.7), ‘sleep’ movements of the leaves and leaflets of many legumes, guard cells of stomata. Some plants also respond to touch. Some claim the dancing plant improves its movement with music. Watch the first minute of this clip to see the dancing plant in action! The best example is Indian telegraph plant, Desmodium gyrans, where up and down movements of the two lateral leaflets occur in a rhythmic manner. I started watching the BBC documentary In the Mind of Plants a film by Jacques Mitsch. [cited 19 Jan 2017]; Avaliable from: pgis.lk (http://www.pgis.lk/yrf/sci2015/cvk_ileperuma.pdf). Perhaps the plant neuroscience researchers will find a way of having ability to improve sound induced movements in experiments. Desmodium Gyrans is one of the few plants on earth capable of independent instant movement. http://link.springer.com/chapter/10.1007/978-3-642-29110-4_4. The few species that exhibit rapid movements such as the sensitive plant (Mimosa pudica) and the Venus fly trap (Dionaea muscipula) have become quite famous as a result. A simple touch, change in temperature or sound will cause the plant to dance. It leaves are sensitive to vibrations, touch and temperature. Depolarization leads to shortening of cels on one side and hyper-polarized leads to elongated cells on the other side of the pulvinus (Ellingsurd 1993. So perhaps sound induced movement is to attract someone. Codariocalyx motorius, aka Desmodium gyrans (Fabaceae) This tropical Asian shrub is widely distributed throughout South Asia including Sri Lanka, as well as in East and East-Southern regions of Asia. Yes, plants do move. Available from: International Journal for Pharmaceutical Sciences and Research at ijpsr.com. Dancing Plant, Telegraph Plant, Semaphore Plant, • Bengali: Nageswar, Ban chandal • Hindi: Dudli • Tamil: Thozhuganni. Add to Wish List. They also move to follow gravity such as roots knowing to move downward into moist soil. Abstract The minute‐range up and down movements of the lateral leaflets of Desmodium gyrans have been studied after exposure to pulses of DC current. There is much resemblance between such semi-automatic phenomena in Biophytum and the well-known instance of spontaneous movements exhibited by Desmodium gyrans, the successive mechanical responses of which exhibit all the peculiarities of multiple response as seen in Biophytum. Desmodium gyrans were tested for the antimicrobial and wound healing properties. Believe it or not, there is a plant that also enjoys grooving to the beat.” (funflowerfacts.com 2013). But Codariocalyx motorius or Desmodium roylei or Meibomia gyrans, or whatever you choose to call it, actually dances. The Telegraph plant--also called Codariocalyx motorius, Desmodium gyrans, dancing plant, or semaphore plant--is often listed as one of the top 10 most unusual plants in existence. A preliminary screening of the medicinal plant. Flowers with movement, dancing plants, carnivorous plants, mimosa pudica, codariocalyx motorius, venus flytrap. I started watching the BBC documentary. It is most hypothesized that the movement is to obtain optimum sunlight for the larger leaves. Some other common names include the dancing plant or telegraph plant. The arch described by each of them is roughly 50°. Aside from reacting to sound the dancing plant also has some other interesting features. What’s really sending folks on a dance is that Codariocalyx motorius moves when stimulated by sound and we don’t know why! also known as the ‘dancing’ plant, telegraph plant, or semaphore plant, belongs to the Fabaceae family. Springer. The leaves of Desmodium gyrans (L.F.) DC show circadian movements in the terminal and ultradian movements of the lateral leaflets. Raven, Peter. The leaves of Desmodium gyrans (L.F.) DC show circadian movements in the terminal and ultradian movements of the lateral leaflets. The Thai botanist in the Youtube allegedly spent a small fortune and 7+ years growing strains. Much like Jack was astonished by the plant that germinated in the fairytale, I was completely intrigued that a bean could grow such a marvelous plant. As the water landed on its pointed little leaflets, it set the plant twitching, and Darwin measured the movements. 2004. It is used medicinally and is usually listed among the more unusual plants in the world. Networks of these telegraphs were strewn all over Europe and communication was much quicker than by horseback. Autonomous movements are similar to seis-monasties. (2) Movements of Growth: Due to unequal growth on different sides of an organ, the growing organ shows movements … International Journal for Pharmaceutical Sciences and Research. Ileperuma, C. V. K.. 2015. These movements occur in jumps. Many alkaloids are present in these parts that are used medicinally. 2008. Ohashi. It comes mainly from the grasslands of Asia. Movement of the bracteoles occurs continuously and is sufficiently rapid to be discernible with the naked eye. http://www.newyorker.com/magazine/2013/12/23/the-intelligent-plant. 2013. Young Researchers’ Forum – PGIS [Internet]. And we’re not talking about animals. Plant Electrophysiology: Signaling and Responses. During day time, the two lateral leaflets exhibit peculiar and interesting movements. It seems as if the mystery remains as to why C. motorius reacts with rapid motion to sound. In a study with a similar rapidly moving Fabaceae, Mimosa pudica, it was hypothesized plants have an “animal-like” learning behavior. Nyctinastic “night closure” movements of C. motorius. These movements occur due to periodic variations in the turgidity of cells of an organ. The Enigmatic Fast Leaflet Rotation in Desmodium motorium. Generally they move to to follow light. Available from: International Journal for Pharmaceutical Sciences and Research at ijpsr.com. It is proposed that the ultradian rhythms of the lateral leaflets are the outcome of the processes involved in the shrinking and expanding of the motor cells. Alkaloids are secondary metabolites, plant chemicals that help plants survive in their given environments..The dancing plant is a lovely perennial that matures two to four feet tall and produces purple flowers. Volkov, Alaxander. Believe it or not, there is a plant that also enjoys grooving to the beat.” (funflowerfacts.com 2013). Also known as the dancing plant, the telegraph plant (Codariocalyx motorius – formerly Desmodium gyrans) is a fascinating tropical plant that dances as the leaves move up and down in bright light. Raven 2004)! It is most hypothesized that the movement is to obtain optimum sunlight for the larger leaves. The electronic telegraph machines didn't appear until the mid-1800s. Perturbations of plant leaflet rhythms caused by electromagnetic radio-frequency radiation. Each bract rises and falls alternately. Unfortunately my plans and hopes for germinating seeds in time to record my own observations for this blog were unfruitful because shipping took a while. It seems that many people are more hopeful optimists rather than bringing up supporting evidence and solid facts. [cited 19 Jan 2017]; Avaliable from: pgis.lk (, http://www.pgis.lk/yrf/sci2015/cvk_ileperuma.pdf. It is prevalent in many processes in functions of plants. http://www.tandfonline.com/doi/full/10.4161/psb.24473?scroll=top&needAccess=true. The ‘dancing’ plant: (Houtt.) They also move to follow gravity such as roots knowing to move downward into moist soil. (Linn .F) DC for its antimicrobial, phytochemical and wound healing properties. It is native to Southeast Asia. Darwin called the plant Hedysarum; modern botanists call it either Desmodium gyrans, or more correctly these days, Codariocalyx motorius. It is native to Southeast Asia. As I began to delve further into the realm of C. motorius, I found you can order seeds! These ions diffuse auxin through the cells. The moving object is recorded by a video camera, digitized by a frame grabber of a computer … http://link.springer.com/chapter/10.1007/978-3-642-29110-4_4. I still plan to germinate in the near future and you can try it our yourself from Etsy! Ohashi. 21.2). For example, in the Indian telegraph plant (Des-modium gyrans) the compound leaf consists of a large blade and two smaller lateral blades that rise and fall like a semaphore. Typically found thriving and jiving in many tropical countries such as Bangladesh, India, Laos, Thailand, Sri Lanka and more (Kalirajan 2012). A. Ranjit Singh* . Fortunately no cows were lost during this transaction. It is a sensitive tropical plant that has the particularity of dancing, moving to the sound of music. A preliminary screening of the medicinal plant Desmodium gyrans (Linn .F) DC for its antimicrobial, phytochemical and wound healing properties. What has held the fascination of botany and plant physiology communities is not the medicinal properties, the life cycle of the plant or flowering habits. Board of Study in Plant Sciences Codariocalyx motorius(or Desmodium gyrans(L.f.) DC.) Scientists still don’t have answers. It is also suggested that the reaction to sound could occur to mimic butterfly movement or general winged arthropod mimicry to attract or deter other species (Lev-Yadun 2013).The leaflets of the dancing plant visibly move in an elliptical fashion when exposed to high pitch (high frequency) sound waves (Ellingsurd 1993). a film by Jacques Mitsch. Codariocalyx motorius), also known as telegraph plant. Pub Med Central. 20 http://onlinelibrary.wiley.com/doi/10.1002/bem.2250140309/abstract.
