  • Botanical drawing of a Rustlepip


    The Amphorafonia domestica, but let’s use its common name: the rustlepip, is a plant that can do with very little water or soil to obtain nutrition, only in the early growing stages it needs soil to grow on until the airroots are developed so that it can lift itself of the ground and stand on these roots. This plant needs sound as a source of energy. Through a process called phonosynthesis it transforms soundwaves into a starch like substance that can be stored inside various parts of the plant.
    Some of the access energy is stored inside little hardened pellets made up from the same starch and collect in the hollow bulky stem where they can roll around when the plant is moved. By moving the plant, the pellets called rustlepips, make a rustling sound and release some of their energy. This energy can even spread to the person that is moving the plant, giving the person a slight euphoric feeling.

    Little is known of the organisms that use sound to synthesize their own food from inorganic substances like carbon dioxide. We can find information about: photoautotrophs, chemoautotrophs etc. but scarcely any information about phonoautotrophs.
    Since I grow plants that are phonoautotroph, the Amphorafonia domestica also known as Rustlepip, it seemed helpful to share some information about this process of synthesizing food from inorganic substances using sound as an energy source.

    The process that phonoautotrophic plants use for the conversion of carbon dioxide to organic compounds is called phonosynthesis. So, carbon assimilation can take place in the absence of sunlight, like in chemosynthesis which is also a form of carbon assimilation. This gives the phonoautotroph an advantage, it can process food day and night. It also means that they can live in environments where sunlight is completely absent, like in cave systems. As long as there is sound, they can grow and prosper. The slightest sounds will do, like soft whispering draught or the flutter of batwings. Because most phonoautotrophs prefer a dry environment over a wet one, they can not be found in caves that are moist or get flooded occasionally.  The plants that I grow are completely domesticated and can not be found living in the wild. However, I am convinced that the wild variety can be found in remote and desolate parts of our planet.

    Because its independence of sunlight it is thought possible that phonoautotrophs like the wild variety of Amphorafonia domestica, might be capable of living on other planets that are to far from any sun in the galaxy. So, a question arises: do they originate from a different planet to begin with? But to that question I have no answer, hopefully we can learn more in the future when deep space probes travel further into the unknown. Maybe the first living organisms that we encounter on a remote and dark planet, will be the ancestors of the Rustlepip!

    Medal from the society of Amphorafonia d. owners

    Founder of the society of Amphorafonia owners

    Palaeontologist Prof. Walter K. Leysius was born on March 11, 1921, son of Kornelis Leysius and Antje Dekker. His father was a schoolteacher in Blokzijl, a town in the province Overijssel.
    Kornelis was an enthusiastic amateur biologist, after the example of Jac. P. Thijsse who also was a teacher. The deep love from his father of the natural world and al things growing, was an inspiration to the young Walter. A study of biology would have been a good choice, but palaeontology was the way forward for Walter. Funny fact that later in his life, the discovery of two fossilised rustlepips would make him take up a botanic study. The fossils where found in the chalk quarry of Winterswijk in the year 1966.
    This discovery changed his life. He had to know everything about this strange fossilised specimen and so he started his research. In 1972 he founded the society of Amphorafonia owners where members would be able to share their knowledge and expertise and to undertake educational daytrips. He even had designed a medal to be presented to the member that had made a special contribution to the society. Its sad to say that the society was no success. In total there only have ever been seven members and in 1978 the society was dissolved. One of the medals, the one that Walter reserved for himself, is now in my possession.

    Pieter Ruyschhaer, botanist

    In the book “Cruydeboeck der byzondere ende seltsaame ghewassen” from author Pieter Ruyschhaer is a description of a most peculiar plant by the name: Amphorafonia domestica.
    The book is about five hundred years old, written by Pieter Ruyschhaer, a botanist who lived from 1458 until 1524 in the province Gelderland, the Netherlands. Ruyschhaer first discovered the Amphorafonia when someone showed him a woodprint depicting two noble ladies exchanging an Amphorafonia.
    This inspired him to study the plant. His research took him to the tiny city of Bredevoort where, according to rumours, a man lived who was growing strange rustling plants. And indeed, there on the edge of a large forest surrounding the city he found a small cottage filled with rustlepips. The cottage belonged to a recluse, a man of few words but with a look of eternal bliss in his green eyes.  Probably the good man was in a constant state of euphoria due to the powerful energy that his plants where radiating. For Pieter Ruischhaer this was the beginning of a lifelong addiction to the Amphorafonia domestica, and with a beautiful specimen carefully wrapped in his cloak he travelled back to his home in Zutphen.
